 are impossible to fix once merged. Please rebase your branch on
 zeromq/libzmq master instead of merging it.

-```
 git remote add upstream git@github.com:zeromq/libzmq.git
 git fetch upstream
 git rebase upstream/master
 git push -f
-```

 In case you already merged instead of rebasing you can drop the merge commit.

-```
 git rebase -i HEAD~10
-```

 Now, find your merge commit and mark it as drop and save. Finally rebase!

+                      GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+		         GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions. 
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version. 
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.
+
+--------------------------------------------------------------------------------
+
+           SPECIAL EXCEPTION GRANTED BY COPYRIGHT HOLDERS
+
+As a special exception, copyright holders give you permission to link this
+library with independent modules to produce an executable, regardless of
+the license terms of these independent modules, and to copy and distribute
+the resulting executable under terms of your choice, provided that you also
+meet, for each linked independent module, the terms and conditions of
+the license of that module. An independent module is a module which is not
+derived from or based on this library. If you modify this library, you must
+extend this exception to your version of the library.

+of this license, and section 6 of the GNU General Public License.

-become effective for each Contribution on the date the Contributor first
-distributes such Contribution.
-
-2.3. Limitations on Grant Scope
-
-The licenses granted in this Section 2 are the only rights granted under
-this License. No additional rights or licenses will be implied from the
-distribution or licensing of Covered Software under this License.
-Notwithstanding Section 2.1(b) above, no patent license is granted by a
-Contributor:
-
-(a) for any code that a Contributor has removed from Covered Software;
-    or
-
-(b) for infringements caused by: (i) Your and any other third party's
-    modifications of Covered Software, or (ii) the combination of its
-    Contributions with other software (except as part of its Contributor
-    Version); or
-
-(c) under Patent Claims infringed by Covered Software in the absence of
-    its Contributions.
-
-This License does not grant any rights in the trademarks, service marks,
-or logos of any Contributor (except as may be necessary to comply with
-the notice requirements in Section 3.4).
-
-2.4. Subsequent Licenses
-
-No Contributor makes additional grants as a result of Your choice to
-distribute the Covered Software under a subsequent version of this
-License (see Section 10.2) or under the terms of a Secondary License (if
-permitted under the terms of Section 3.3).

-Contributions are its original creation(s) or it has sufficient rights
-to grant the rights to its Contributions conveyed by this License.
-
-2.6. Fair Use

-applicable copyright doctrines of fair use, fair dealing, or other
-equivalents.
-
-2.7. Conditions

-Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
-in Section 2.1.
-
-3. Responsibilities
-------------------
-
-3.1. Distribution of Source Form
-
-All distribution of Covered Software in Source Code Form, including any
-Modifications that You create or to which You contribute, must be under
-the terms of this License. You must inform recipients that the Source
-Code Form of the Covered Software is governed by the terms of this
-License, and how they can obtain a copy of this License. You may not
-attempt to alter or restrict the recipients' rights in the Source Code
-Form.
-
-3.2. Distribution of Executable Form
-
-If You distribute Covered Software in Executable Form then:
-
-(a) such Covered Software must also be made available in Source Code
-    Form, as described in Section 3.1, and You must inform recipients of
-    the Executable Form how they can obtain a copy of such Source Code
-    Form by reasonable means in a timely manner, at a charge no more
-    than the cost of distribution to the recipient; and
-
-(b) You may distribute such Executable Form under the terms of this
-    License, or sublicense it under different terms, provided that the
-    license for the Executable Form does not attempt to limit or alter
-    the recipients' rights in the Source Code Form under this License.
-
-3.3. Distribution of a Larger Work
-
-You may create and distribute a Larger Work under terms of Your choice,
-provided that You also comply with the requirements of this License for
-the Covered Software. If the Larger Work is a combination of Covered
-Software with a work governed by one or more Secondary Licenses, and the
-Covered Software is not Incompatible With Secondary Licenses, this
-License permits You to additionally distribute such Covered Software
-under the terms of such Secondary License(s), so that the recipient of
-the Larger Work may, at their option, further distribute the Covered
-Software under the terms of either this License or such Secondary
-License(s).
-
-3.4. Notices
-
-You may not remove or alter the substance of any license notices
-(including copyright notices, patent notices, disclaimers of warranty,
-or limitations of liability) contained within the Source Code Form of
-the Covered Software, except that You may alter any license notices to
-the extent required to remedy known factual inaccuracies.
-
-3.5. Application of Additional Terms
-
-You may choose to offer, and to charge a fee for, warranty, support,
-indemnity or liability obligations to one or more recipients of Covered
-Software. However, You may do so only on Your own behalf, and not on
-behalf of any Contributor. You must make it absolutely clear that any
-such warranty, support, indemnity, or liability obligation is offered by
-You alone, and You hereby agree to indemnify every Contributor for any
-liability incurred by such Contributor as a result of warranty, support,
-indemnity or liability terms You offer. You may include additional
-disclaimers of warranty and limitations of liability specific to any
-jurisdiction.
-
-4. Inability to Comply Due to Statute or Regulation
---------------------------------------------------
-
-If it is impossible for You to comply with any of the terms of this
-License with respect to some or all of the Covered Software due to
-statute, judicial order, or regulation then You must: (a) comply with
-the terms of this License to the maximum extent possible; and (b)
-describe the limitations and the code they affect. Such description must
-be placed in a text file included with all distributions of the Covered
-Software under this License. Except to the extent prohibited by statute
-or regulation, such description must be sufficiently detailed for a
-recipient of ordinary skill to be able to understand it.
-
-5. Termination
--------------
-
-5.1. The rights granted under this License will terminate automatically
-if You fail to comply with any of its terms. However, if You become
-compliant, then the rights granted under this License from a particular
-Contributor are reinstated (a) provisionally, unless and until such
-Contributor explicitly and finally terminates Your grants, and (b) on an
-ongoing basis, if such Contributor fails to notify You of the
-non-compliance by some reasonable means prior to 60 days after You have
-come back into compliance. Moreover, Your grants from a particular
-Contributor are reinstated on an ongoing basis if such Contributor
-notifies You of the non-compliance by some reasonable means, this is the
-first time You have received notice of non-compliance with this License
-from such Contributor, and You become compliant prior to 30 days after
-Your receipt of the notice.
-
-5.2. If You initiate litigation against any entity by asserting a patent
-infringement claim (excluding declaratory judgment actions,
-counter-claims, and cross-claims) alleging that a Contributor Version
-directly or indirectly infringes any patent, then the rights granted to
-You by any and all Contributors for the Covered Software under Section
-2.1 of this License shall terminate.
-
-5.3. In the event of termination under Sections 5.1 or 5.2 above, all
-end user license agreements (excluding distributors and resellers) which
-have been validly granted by You or Your distributors under this License
-prior to termination shall survive termination.

----------------
-
-This License represents the complete agreement concerning the subject
-matter hereof. If any provision of this License is held to be
-unenforceable, such provision shall be reformed only to the extent
-necessary to make it enforceable. Any law or regulation which provides

-10. Versions of the License
---------------------------
-
-10.1. New Versions
-
-Mozilla Foundation is the license steward. Except as provided in Section

-* Relicensing from LGPL-3.0+ (with custom exceptions) to MPL-2.0 is now complete.
-  libzmq is now distributed under the Mozilla Public License 2.0. Relicensing
-  grants have been collected from all relevant authors, and some functionality
-  has been clean-room reimplemented where that was not possible. In layman terms,
-  the new license provides the same rights and obligations as before. Source
-  files are now tagged using the SPDX license identifier format.
-  Details of the relicensing process can be seen at:
-  https://github.com/zeromq/libzmq/issues/2376

-0MQ version 4.3.3 stable, released on 2020/09/07
-================================================
-
-* Security advisories:
-  * CVE-2020-15166: Denial-of-Service on CURVE/ZAP-protected servers by
-    unauthenticated clients.
-    If a raw TCP socket is opened and connected to an endpoint that is fully
-    configured with CURVE/ZAP, legitimate clients will not be able to exchange
-    any message. Handshakes complete successfully, and messages are delivered to
-    the library, but the server application never receives them.
-    For more information see the security advisory:
-    https://github.com/zeromq/libzmq/security/advisories/GHSA-25wp-cf8g-938m
-  * Stack overflow on server running PUB/XPUB socket (CURVE disabled).
-    The PUB/XPUB subscription store (mtrie) is traversed using recursive
-    function calls. In the remove (unsubscription) case, the recursive calls are
-    NOT tail calls, so even with optimizations the stack grows linearly with the
-    length of a subscription topic. Topics are under the control of remote
-    clients - they can send a subscription to arbitrary length topics. An
-    attacker can thus cause a server to create an mtrie sufficiently large such
-    that, when unsubscribing, traversal will cause a stack overflow.
-    For more information see the security advisory:
-    https://github.com/zeromq/libzmq/security/advisories/GHSA-qq65-x72m-9wr8
-  * Memory leak in PUB server induced by malicious client(s) without CURVE/ZAP.
-    Messages with metadata are never processed by PUB sockets, but the metadata
-    is kept referenced in the PUB object and never freed.
-    For more information see the security advisory:
-    https://github.com/zeromq/libzmq/security/advisories/GHSA-4p5v-h92w-6wxw
-  * Memory leak in client induced by malicious server(s) without CURVE/ZAP.
-    When a pipe processes a delimiter and is already not in active state but
-    still has an unfinished message, the message is leaked.
-    For more information see the security advisory:
-    https://github.com/zeromq/libzmq/security/advisories/GHSA-wfr2-29gj-5w87
-  * Heap overflow when receiving malformed ZMTP v1 packets (CURVE disabled).
-    By crafting a packet which is not valid ZMTP v2/v3, and which has two
-    messages larger than 8192 bytes, the decoder can be tricked into changing
-    the recorded size of the 8192 bytes static buffer, which then gets overflown
-    by the next message. The content that gets written in the overflown memory
-    is entirely decided by the sender.
-    For more information see the security advisory:
-    https://github.com/zeromq/libzmq/security/advisories/GHSA-fc3w-qxf5-7hp6
-
-* Note for packagers: an external, self-contained sha1 library is now
-  included in the source tree under external/sha1/ - it is licensed
-  under BSD-3-Clause and thus it is fully compatible with libzmq's
-  license.
-  It is only used if WebSockets support is enabled, and if neither GnuTLS nor
-  NSS are available.
-
-* Note for packagers: an internal reimplementation of strlcpy is now included,
-  for wider platform compatibility.
-  libbsd can be used and is enabled by default if available instead of the
-  internal implementation, for better security maintenance in distros.
-
-* Note for packagers: ZeroMQConfig.cmake is now installed in the arch-dependent
-  subdirectory - eg: /usr/lib/x86_64-linux-gnu/cmake/
-
-* New DRAFT (see NEWS for 4.2.0) socket type:
-  - ZMQ_CHANNEL is a thread-safe alternative to ZMQ_PAIR.
-  See doc/zmq_socket.txt for details.
-
-* New DRAFT (see NEWS for 4.2.0) socket option:
-  - ZMQ_ONLY_FIRST_SUBSCRIBE will cause only the first part of a multipart
-    message to be processed as a subscribe/unsubscribe message, and the rest
-    will be forwarded as user data to the application.
-  - ZMQ_RECONNECT_STOP will cause a connecting socket to stop trying to
-    reconnect in specific circumstances. See the manpage for details.
-  - ZMQ_HELLO_MSG to set a message that will be automatically sent to a new
-    connection.
-  - ZMQ_DISCONNECT_MSG to set a message that will be automatically received when
-    a peer disconnects.
-  See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
-
-* New DRAFT (see NEWS for 4.2.0) zmq_ctx_get_ext/zmq_ctx_set_ext APIs were added
-  to allow enhancing the context options with variable data inputs.
-  See doc/zmq_ctx_get_ext.txt and doc/zmq_ctx_set_ext.txt for details.
-
-* New DRAFT (see NEWS for 4.2.0) transport options WS and WSS added for support
-  of WebSockets (and secure WebSockets via TLS) via the ZWS 2.0 protocol.
-  WSS requires the GnuTLS library for TLS support. ZMQ_WSS_ specific socket
-  options were added to support TLS.
-  WebSockets support is disabled by default if DRAFT APIs are disabled.
-
-* New DRAFT (see NEWS for 4.2.0) socket type, PEER, which is thread safe and a
-  related zmq_connect_peer function which atomically and thread-safely connects
-  and returns a routing-id.
-
-* New DRAFT (see NEWS for 4.2.0) zmq_msg_init_buffer API was added to allow
-  the construction of a message by copying from an existing buffer.
-
-* New DRAFT (see NEWS for 4.2.0) zmq_poller_size API was added to allow querying
-  the number of sockets/fds registered in a zmq_poller.
-
-* ZMTP 3.1 peers will receive subscribe/cancel on PUB/SUB via commands rather
-  than using the first byte of the payload.
-
-* zmq_z85_decode now checks that the input string's length is at least 5 characters
-  and always a multiple of 5 as per API specification.
-
-* Fixed #3566 - malformed CURVE message can cause memory leak

-0MQ version 4.3.2 stable, released on 2019/07/08
-================================================
-
-* CVE-2019-13132: a remote, unauthenticated client connecting to a
-  libzmq application, running with a socket listening with CURVE
-  encryption/authentication enabled, may cause a stack overflow and
-  overwrite the stack with arbitrary data, due to a buffer overflow in
-  the library. Users running public servers with the above configuration
-  are highly encouraged to upgrade as soon as possible, as there are no
-  known mitigations. All versions from 4.0.0 and upwards are affected.
-  Thank you Fang-Pen Lin for finding the issue and reporting it!
-
-* New DRAFT (see NEWS for 4.2.0) zmq_socket_monitor_versioned API that supports
-  a versioned monitoring events protocol as a parameter. Passing 1 results in
-  the same behaviour as zmq_socket_monitor.
-  Version 2 of the events protocol allows new events, new metadata, different
-  socket types for the monitors and more. It is described in details in
-  doc/zmq_socket_monitor_versioned.txt
-
-* New DRAFT (see NEWS for 4.2.0) zmq_socket_monitor_pipes_stats that triggers
-  a new ZMQ_EVENT_PIPES_STATS to be delivered via zmq_socket_monitor_versioned
-  v2 API, which contains the current status of all the queues owned by the
-  monitored socket. See doc/zmq_socket_monitor_versioned.txt for details.
-
-* New DRAFT (see NEWS for 4.2.0) zmq_poller_fd that returns the FD of a thread
-  safe socket. See doc/zmq_poller.txt for details.
-
-* New DRAFT (see NEWS for 4.2.0) socket options:
-  - ZMQ_XPUB_MANUAL_LAST_VALUE is similar to ZMQ_XPUB_MANUAL but allows to avoid
-    duplicates when using last value caching.
-  - ZMQ_SOCKS_USERNAME and ZMQ_SOCKS_PASSWORD that implement SOCKS5 proxy
-    authentication.
-  See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
-
-* Implemented background thread names for Windows, when the Visual Studio
-  debugger is being used.
-
-* Fixed #3358 - test_security_zap failing due to SIGBUS on SPARC64, hard-coded
-                IPC socket binds in tests cause race conditions
-
-* Fixed #3361 - enabling GSSAPI support (when using autools) does not work due
-                to regression introduced in 4.2.3
-
-* Fixed #3362 - remove documentation for ZMQ_THREAD_PRIORITY context option
-                getter, it's not implemented
-
-* Fixed #3363 - tests fail to build due to stricter compiler printf validation
-                in new versions of GCC
-
-* Fixed #3367 - try to infer cacheline size at build time, first with
-                getconf LEVEL1_DCACHE_LINESIZE, and then by reading
-                /sys/devices/system/cpu/cpu0/cache/index0/coherency_line_size
-                (autoconf only), and only then falling back to the previous
-                default of 64 bytes. Avoids false sharing on POWER and s390x.
-                Import ax_func_posix_memalign.m4 as a more reliable check for
-                posix_memalign presence on some unix platforms.
-                Prefer c++11 atomic primitives to compiler intrinsics, when
-                both are available, as the former is more reliable.
-                Set test_pair_ipc and test_rebind_ipc to XFAIL on GNU/Hurd due
-                to non-functioning getsockname on AF_UNIX.

-* Fixed #3385 - TCP port in ZMQ_LAST_ENDPOINT depends on global locale
-
-* Fixed #3404 - use std::condition_variable_any when possible
-
-* Fixed #3436 - reconnect interval exponential backoff and may lead to integer
-                overflows
-
-* Fixed #3440 - improve zmq_proxy performance by batching of up to 1000

-
-0MQ version 4.3.1 stable, released on 2019/01/12
-================================================
-
-* CVE-2019-6250: A vulnerability has been found that would allow attackers to
-  direct a peer to jump to and execute from an address indicated by the
-  attacker.
-  This issue has been present since v4.2.0. Older releases are not affected.
-  NOTE: The attacker needs to know in advance valid addresses in the peer's
-  memory to jump to, so measures like ASLR are effective mitigations.
-  NOTE: this attack can only take place after authentication, so peers behind
-  CURVE/GSSAPI are not vulnerable to unauthenticated attackers.
-  See https://github.com/zeromq/libzmq/issues/3351 for more details.
-  Thanks to Guido Vranken for uncovering the issue and providing the fix!
-
-* Note for packagers: as pkg-config's Requires.private is now used to properly
-  propagate dependencies for static builds, the libzmq*-dev or zeromq-devel or
-  equivalent package should now depend on the libfoo-dev or foo-devel packages
-  of all the libraries that zmq is linked against, or pkg-config --libs libzmq
-  will fail due to missing dependencies on end users machines.
-
-* Fixed #3351 - remote code execution vulnerability.
-
-* Fixed #3343 - race condition in ZMQ_PUSH when quickly disconnecting and
-                reconnecting causes last part of multi-part message to get
-                "stuck" and resent by mistake to the new socket.
-
-* Fixed #3336 - set Requires.private in generate pkg-config file.
-
-* Fixed #3334 - set TCP_NODELAY after connect() on Windows for the I/O socket.
-
-* Fixed #3326 - assert on Android when opening a socket and disabling WiFi.
-
-* Fixed #3320 - build failure on OpenBSD with GCC.
-
-0MQ version 4.3.0 stable, released on 2018/11/28
-================================================
-
-* The following DRAFT APIs have been marked as STABLE and will not change
-  anymore:
-  - ZMQ_MSG_T_SIZE context option (see doc/zmq_ctx_get.txt)
-  - ZMQ_THREAD_AFFINITY_CPU_ADD and ZMQ_THREAD_AFFINITY_CPU_REMOVE (Posix only)
-    context options, to add/remove CPUs to the affinity set of the I/O threads.
-    See doc/zmq_ctx_set.txt and doc/zmq_ctx_get.txt for details.
-  - ZMQ_THREAD_NAME_PREFIX (Posix only) context option, to add a specific
-    integer prefix to the background threads names, to easily identify them.
-    See doc/zmq_ctx_set.txt and doc/zmq_ctx_get.txt for details.
-  - ZMQ_GSSAPI_PRINCIPAL_NAMETYPE and ZMQ_GSSAPI_SERVICE_PRINCIPAL_NAMETYPE
-    socket options, for the corresponding GSSAPI features. Additional
-    definitions for principal name types:
-    - ZMQ_GSSAPI_NT_HOSTBASED
-    - ZMQ_GSSAPI_NT_USER_NAME
-    - ZMQ_GSSAPI_NT_KRB5_PRINCIPAL
-    See doc/zmq_gssapi.txt for details.
-  - ZMQ_BINDTODEVICE socket option (Linux only), which will bind the
-    socket(s) to the specified interface. Allows to use Linux VRF, see:
-    https://www.kernel.org/doc/Documentation/networking/vrf.txt
-    NOTE: requires the program to be ran as root OR with CAP_NET_RAW
-  - zmq_timers_* APIs. These functions can be used for cross-platforms timed
-    callbacks. See doc/zmq_timers.txt for details.
-  - The following socket monitor events:
-    - ZMQ_EVENT_HANDSHAKE_FAILED_NO_DETAIL: unknown errors during handshake.
-    - ZMQ_EVENT_HANDSHAKE_SUCCEEDED: Handshake completed with authentication.
-    - ZMQ_EVENT_HANDSHAKE_FAILED_PROTOCOL: Protocol errors with peers or ZAP.
-    - ZMQ_EVENT_HANDSHAKE_FAILED_AUTH: Failed authentication requests.
-    See doc/zmq_socket_monitor.txt for more details and error codes.
-  - zmq_stopwatch_intermediate which returns the time elapsed without stopping
-    the stopwatch.
-  - zmq_proxy_steerable command 'STATISTICS' to retrieve stats about the amount
-    of messages and bytes sent and received by the proxy.
-    See doc/zmq_proxy_steerable.txt for more information.
-
-* The build-time configuration option to select the poller has been split, and
-  new API_POLLER (CMake) and --with-api-poller (autoconf) options will now
-  determine what system call is used to implement the zmq_poll/zmq_poller APIs.
-  The previous POLLER and --with-poller options now only affects the
-  internal I/O thread. In case API_POLLER is not specified, the behaviour keeps
-  backward compatibility intact and will be the same as with previous releases.
-
-* The non-default "poll" poller for the internal I/O thread (note: NOT for the
-  zmq_poll/zmq_poller user APIs!) has been disabled on Windows as WSAPoll does
-  not report connection failures. For more information see:
-  - https://daniel.haxx.se/blog/2012/10/10/wsapoll-is-broken/
-  - https://curl.haxx.se/mail/lib-2012-10/0038.html
-  - https://bugs.python.org/issue16507
-
-* New epoll implementation for Windows, using the following implementation:
-  https://github.com/piscisaureus/wepoll/tree/v1.5.4
-  To use this, select "epoll" as the poller option in the build system.
-  Note for distributors: the wepoll source code is embedded and distributed.
-  It is licensed under the BSD-2-Clause and thus it is compatible with LGPL-3.0.
-  Note that, if selected at build time, the license text must be distributed
-  with the binary in accordance to the license terms. A copy can be found at:
-  external/wepoll/license.txt
-
-* The pre-made Visual Studio solutions file are deprecated, and users are
-  encouraged to use the CMake solution generation feature instead.
-
-* New DRAFT (see NEWS for 4.2.0) socket options:
-  - ZMQ_ROUTER_NOTIFY to deliver a notification when a peer connects and/or
-    disconnects in the form of a routing id plus a zero-length frame.
-  - ZMQ_MULTICAST_LOOP to control whether the data sent should be looped back
-    on local listening sockets for UDP multicast sockets (ZMQ_RADIO).
-  See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
-
-* New perf tool, perf/benchmark_radix_tree, to measure the performance of the
-  different internal implementations of the trie algorithm used to track
-  subscriptions. Requires a compiler that supports C++11.
-
-* New autoconf flag "--enable-force-CXX98-compat" which will force -std=gnu++98
-  and, if the compiler supports them (clang++ at the moment), it will also add
-  -Wc++98-compat -Wc++98-compat-pedantic so that compatibility with C++98 can
-  be tested.
-
-* Many, many coding style, duplication and static analysis improvements.
-
-* Many, many improvements to the CMake build system, especially on Windows.
-
-* Many, many improvements to unit tests.
-
-* Fixed #3036 - Compilation error when -pedantic is used.
-
-* Fixed #3028 - Failure when zmq_poller_destroy is called after zmq_ctx_term.

+This document collects grants from firms that hold copyrights in ZeroMQ. Please add new firms at the start. Each patch must be made with a GitHub handle that guarantees identity of the signatory.
+
+## iMatix Corporation
+
+This is a statement by iMatix Corporation sprl (iMatix) that grants permission to relicense its copyrights in the libzmq C++ library (ZeroMQ) under the Mozilla Public License v2 (MPLv2).
+
+1. The original ZeroMQ codebase was developed from 2007-2009 by FastMQ Inc. (FastMQ) in Slovakia, which held all copyrights in code written by its staff.
+
+2. On 2009-11-01, iMatix exercised an option to acquire FastMQ and its assets,
+including ZeroMQ. On or before 2010-01-05 the FastMQ copyrights in ZeroMQ were
+transferred to iMatix ([commit](https://github.com/zeromq/libzmq/commit/4f6baf4dde627656b63cc4e2acdb78a8577ba640)). The FastMQ legal entity was subsequently liquidated.
+
+3. Between 2009 and 2016, iMatix has continued to add contributions to ZeroMQ under the GitHub handle 'hintjens'.
+
+4. This grant therefore covers what remains of the original FastMQ codebase plus all later contributions.
+
+5. iMatix hereby grants an irrevocable, global, and fully paid-up license on all its copyrights that exist in ZeroMQ, under the MPLv2.
+

+CEO, iMatix Corporation sprl
