-Daniel (28 December 1999):
- - Tim Verhoeven correctly identified that curl
-   doesn't support URL formatted file names when getting ftp. Now, there's a
-   problem with getting very weird file names off FTP servers. RFC 959 defines
-   that the file name syntax to use should be the same as in the native OS of
-   the server. Since we don't know the peer server system we currently just
-   translate the URL syntax into plain letters. It is still better and with
-   the solaris 2.6-supplied ftp server it works with spaces in the file names.
-
-Daniel (27 December 1999):
- - When curl parsed cookies straight off a remote site, it corrupted the input
-   data, which, if the downloaded headers were stored made very odd characters
-   in the saved data. Correctly identified and reported by Paul Harrington.
-
-Daniel (13 December 1999):
- - General cleanups in the library interface. There had been some bad kludges
-   added during times of stress and I did my best to clean them off. It was
-   both regarding the lib API as well as include file confusions.
-
-Daniel (3 December 1999):
- - A small --stderr bug was reported by Eetu Ojanen...
-
- - who also brought the suggestion of extending the -X flag to ftp list as
-   well. So, now it is and the long option is now --request instead. It is
-   only for ftp list for now (and the former http stuff too of course).
-
-Lars J. Aas (24 November 1999):
- - Patched curl to compile and build under BeOS. Doesn't work yet though!
-
- - Corrected the Makefile.am files to allow putting object files in
-   different directories than the sources.
-
-Version 6.3.1
-
-Daniel (23 November 1999):
- - I've had this major disk crash. My good old trust-worthy source disk died
-   along with the machine that hosted it. Thank goodness most of all the
-   things I've done are either backed up elsewhere or stored in this CVS
-   server!
-
- - Michael S. Steuer pointed out a bug in the -F handling
-   that made curl hang if you posted an empty variable such as '-F name='. It
-   was one of those old bugs that never have worked properly...
-
- - Jason Baietto pointed out a general flaw in the HTTP
-   download. Curl didn't complain if it was prematurely aborted before the
-   entire download was completed. It does now.
-
-Daniel (19 November 1999):
- - Chris Maltby very accurately criticized the lack of
-   return code checks on the fwrite() calls. I did a thorough check for all
-   occurrences and corrected this.
-
-Daniel (17 November 1999):
- - Paul Harrington pointed out that the -m/--max-time option
-   doesn't work for the slow system calls like gethostbyname()... I don't have
-   any good fix yet, just a slightly less bad one that makes curl exit hard
-   when the timeout is reached.
-
- - Bjorn Reese helped me point out a possible problem that might be the reason
-   why Thomas Hurst experience problems in his Amiga version.
-
- Daniel (12 November 1999):
- - I found a crash in the new cookie file parser. It crashed when you gave
-   a plain http header file as input...
-
-Version 6.3
-
- Daniel (10 November 1999):
- - I kind of found out that the HTTP time-conditional GETs (-z) aren't always
-   respected by the web server and the document is therefore sent in whole
-   again, even though it doesn't match the requested condition. After reading
-   section 13.3.4 of RFC 2616, I think I'm doing the right thing now when I do
-   my own check as well. If curl thinks the condition isn't met, the transfer
-   is aborted prematurely (after all the headers have been received).
-
- - After comments from Robert Linden I also rewrote some parts of the man page
-   to better describe how the -F works.
-
- - Michael Anti put up a new curl download mirror in
-   China:  http://www.pshowing.com/curl/
-
- - I added the list of download mirrors to the README file
-
- - I did add more explanations to the man page
-
- Daniel (8 November 1999):
- - I made the -b/--cookie option capable of reading netscape formatted cookie
-   files as well as normal http-header files. It should be able to
-   transparently figure out what kind of file it got as input.
-
- Daniel (29 October 1999):
- - Another one of Sebastiaan van Erk's ideas (that has been requested before
-   but I seem to have forgotten who it was), is to add support for ranges in
-   FTP downloads. As usual, one request is just a request, when they're two
-   it is a demand. I've added simple support for X-Y style fetches. X has to
-   be the lower number, though you may omit one of the numbers. Use the -r/
-   --range switch (previously HTTP-only).
-
- - Sebastiaan van Erk suggested that curl should be
-   able to show the file size of a specified file. I think this is a splendid
-   idea and the -I flag is now working for FTP. It displays the file size in
-   this manner:
-        Content-Length: XXXX
-   As it resembles normal headers, and leaves us the opportunity to add more
-   info in that display if we can come up with more in the future! It also
-   makes sense since if you access ftp through a HTTP proxy, you'd get the
-   file size the same way.
-
-   I changed the order of the QUOTE command executions. They're now executed
-   just after the login and before any other command. I made this to enable
-   quote commands to run before the -I stuff is done too.
-
- - I found out that -D/--dump-header and -V/--version weren't documented in
-   the man page.
-
- - Many HTTP/1.1 servers do not support ranges. Don't ask me why. I did add
-   some text about this in the man page for the range option. The thread in
-   the mailing list that started this was initiated by Michael Anti.
-
- - I get reports about nroff crashes on solaris 2.6+ when displaying the curl
-   man page. Switch to gnroff instead, it is reported to work(!). Adam Barclay
-   reported and brought the suggestion.
-
- - In a dialogue with Johannes G. Kristinsson we came
-   up with the idea to let -H/--header specified headers replace the
-   internally generated headers, if you happened to select to add a header
-   that curl normally uses by itself. The advantage with this is not entirely
-   obvious, but in Johannes' case it means that he can use another Host: than
-   the one curl would set.
-
- Daniel (27 October 1999):
- - Jongki Suwandi brought a nice patch for (yet another) crash when following
-   a location:. This time you had to follow a https:// server's redirect to
-   get the core.
-
-Version 6.2
-
- Daniel (21 October 1999):
- - I think I managed to remove the suspicious (nil) that has been seen just
-   before the "Host:" in HTTP requests when -v was used.
- - I found out that if you followed a location: when using a proxy, without
-   having specified http:// in the URL, the protocol part was added once again
-   when moving to the next URL! (The protocol part has to be added to the
-   URL when going through a proxy since it has no protocol-guessing system
-   such as curl has.)
- - Benjamin Ritcey reported a core dump under solaris 2.6
-   with OpenSSL 0.9.4. It turned out this was due to a bad free() in main.c
-   that occurred after the download was done and completed.
- - Benjamin found ftp downloads to show the first line of the download meter
-   to get written twice, and I removed that problem. It was introduced with
-   the multiple URL support.
- - Dan Zitter correctly pointed out that curl 6.1 and earlier versions didn't
-   honor RFC 2616 chapter 4 section 2, "Message Headers": "...Field names are
-   case-insensitive..."  HTTP header parsing assumed a certain casing. Dan
-   also provided me with a patch that corrected this, which I took the liberty
-   of editing slightly.
- - Dan Zitter also provided a nice patch for config.guess to better recognize
-   the Mac OS X
- - Dan also corrected a minor problem in the lib/Makefile that caused linking
-   to fail on OS X.
-
- Daniel (19 October 1999):
- - Len Marinaccio came up with some problems with curl.  Since Windows has a
-   crippled shell, it can't redirect stderr and that causes trouble. I added
-   --stderr today which allows the user to redirect the stderr stream to a
-   file or stdout.
-
- Daniel (18 October 1999):
- - The configure script now understands the '--without-ssl' flag, which now
-   totally disable SSL/https support. Previously it wasn't possible to force
-   the configure script to leave SSL alone. The previous functionality has
-   been retained. Troy Engel helped test this new one.
-
-Version 6.1
-
- Daniel (17 October 1999):
- - I ifdef'ed or commented all the zlib stuff in the sources and configure
-   script. It turned out we needed to mock more with zlib than I initially
-   thought, to make it capable of downloading compressed HTTP documents and
-   uncompress them on the fly. I didn't mean the zlib parts of curl to become
-   more than minor so this means I halt the zlib expedition for now and wait
-   until someone either writes the code or zlib gets updated and better
-   adjusted for this kind of usage.  I won't get into details here, but a
-   short a summary is suitable:
-   - zlib can't automatically detect whether to use zlib or gzip
-     decompression methods.
-   - zlib is very neat for reading gzipped files from a file descriptor,
-     although not as nice for reading buffer-based data such as we would
-     want it.
-   - there are still some problems with the win32 version when reading from
-     a file descriptor if that is a socket
-
- Daniel (14 October 1999):
- - Moved the (external) include files for libcurl into a subdirectory named
-   curl and adjusted all #include lines to use <curl/XXXX> to maintain a
-   better name space and control of the headers. This has been requested.
-
- Daniel (12 October 1999):
- - I modified the 'maketgz' script to perform a 'make' too before a release
-   archive is put together in an attempt to make the time stamps better and
-   hopefully avoid the double configure-running that use to occur.
-
- Daniel (11 October 1999):
- - Applied J<>rn's patches that fixes zlib for mingw32 compiles as well as
-   some other missing zlib #ifdef and more text on the multiple URL docs in
-   the man page.
-
-Version 6.1beta
-
- Daniel (6 October 1999):
- - Douglas E. Wegscheid sent me a patch that made the exact same thing as I
-   just made: the -d switch is now capable of reading post data from a named
-   file or stdin.  Use it similarly to the -F. To read the post data from a
-   given file:
-
-        curl -d @path/to/filename www.postsite.com
-
-   or let curl read it out from stdin:
-
-        curl -d @- www.postit.com
-
- J<>rn Hartroth (3 October 1999):
- - Brought some more patches for multiple URL functionality. The MIME
-   separation ideas are almost scrapped now, and a custom separator is being
-   used instead. This is still compile-time "flagged".
-
- Daniel
- - Updated curl.1 with multiple URL info.
-
- Daniel (30 September 1999):
- - Felix von Leitner brought openssl-check fixes for configure.in to work
-   out-of-the-box when the openssl files are installed in the system default
-   dirs.
-
- Daniel (28 September 1999)
- - Added libz functionality. This should enable decompressing gzip, compress
-   or deflate encoding HTTP documents. It also makes curl send an accept that
-   it accepts that kind of encoding. Compressed contents usually shortens
-   download time. I *need* someone to tell me a site that uses compressed HTTP
-   documents so that I can test this out properly.
-
- - As a result of the adding of zlib awareness, I changed the version string
-   a little. I plan to add openldap version reporting in there too.
-
- Daniel (17 September 1999)
- - Made the -F option allow stdin when specifying files. By using '-' instead
-   of file name, the data will be read from stdin.
-
-Version 6.0
-
- Daniel (13 September 1999)
- - Added -X/--http-request <request> to enable any HTTP command to be sent.
-   Do not that your server has to support the exact string you enter. This
-   should possibly a string like DELETE or TRACE.
-
- - Applied Douglas' mingw32-fixes for the makefiles.
-
- Daniel (10 September 1999)
- - Douglas E. Wegscheid pointed out a problem. Curl didn't check the FTP
-   servers return code properly after the --quote commands were issued. It
-   took anything non 200 as an error, when all 2XX codes should be accepted as
-   OK.
-
- - Sending cookies to the same site in multiple lines like curl used to do
-   turned out to be bad and breaking the cookie specs. Curl now sends all
-   cookies on a single Cookie: line. Curl is not yet RFC 2109 compliant, but I
-   doubt that many servers do use that syntax (yet).
-
- Daniel (8 September 1999)
- - J<>rn helped me make sure it still compiles nicely with mingw32 under win32.
-
- Daniel (7 September 1999)
- - FTP upload through proxy is now turned into a HTTP PUT. Requested by
-   Stefan Kanthak.
-
- - Added the ldap files to the .m32 makefile.
-
- Daniel (3 September 1999)
- - Made cookie matching work while using HTTP proxy.
-
- Bjorn Reese (31 August 1999)
- - Passed his ldap:// patch. Note that this requires the openldap shared
-   library to be installed and that LD_LIBRARY_PATH points to the
-   directory where the lib will be found when curl is run with a
-   ldap:// URL.
-
- J<>rn Hartroth (31 August 1999)
- - Made the Mingw32 makefiles into single files.
- - Made file:// work for Win32. The same code is now used for unix as well for
-   performance reasons.
-
- Douglas E. Wegscheid (30 August 1999)
- - Patched the Mingw32 makefiles for SSL builds.
-
- Matthew Clarke (30 August 1999)
- - Made a cool patch for configure.in to allow --with-ssl to specify the
-   root dir of the openssl installation, as in
-
-        ./configure --with-ssl=/usr/ssl_here
-
- - Corrected the 'reconf' script to work better with some shells.
-
- J<>rn Hartroth (26 August 1999)
- - Fixed the Mingw32 makefiles in lib/ and corrected the file.c for win32
-   compiles.
-
-Version 5.11
-
- Daniel (25 August 1999)
- - John Weismiller pointed out a bug in the header-line
-   realloc() system in download.c.
-
- - I added lib/file.[ch] to offer a first, simple, file:// support. It
-   probably won't do much good on win32 system at this point, but I see it
-   as a start.
-
- - Made the release archives get a Makefile in the root dir, which can be
-   used to start the compiling/building process easier. I haven't really
-   changed any INSTALL text yet, I wanted to get some feed-back on this
-   first.
-
- Daniel (17 August 1999)
- - Another Location: bug. Curl didn't do proper relative locations if the
-   original URL had cgi-parameters that contained a slash. Nusu's page
-   again.
-
- - Corrected the NO_PROXY usage. It is a list of substrings that if one of
-   them matches the tail of the host name it should connect to, curl should
-   not use a proxy to connect there. Pointed out to me by Douglas
-   E. Wegscheid.  I also changed the README text a little regarding this.
-
- Daniel (16 August 1999)
- - Fixed a memory bug with http-servers that sent Location: to a Location:
-   page. Nusu's page showed this too.
-
- - Made cookies work a lot better. Setting the same cookie name several times
-   used to add more cookies instead of replacing the former one which it
-   should've. Nusu <nus at intergorj.ro> brought me an URL that made this
-   painfully visible...
-
- Troy (15 August 1999)
- - Brought new .spec files as well as a patch for configure.in that lets the
-   configure script find the openssl files better, even when the include
-   files are in /usr/include/openssl
-
-Version 5.10
-
- Daniel (13 August 1999)
- - SSL_CTX_set_default_passwd_cb() has been modified in the 0.9.4 version of
-   OpenSSL. Now why couldn't they simply add a *new* function instead of
-   modifying the parameters of an already existing function? This way, we get
-   a compiler warning if compiling with 0.9.4 but not with earlier. So, I had
-   to come up with a #if construction that deals with this...
-
- - Made curl output the SSL version number get displayed properly with 0.9.4.
-
- Troy (12 August 1999)
- - Added MingW32 (GCC-2.95) support under Win32. The INSTALL file was also
-   a bit rearranged.
- 
- Daniel (12 August 1999)
- - I had to copy a good <arpa/telnet.h> include file into the curl source
-   tree to enable the silly win32 systems to compile. The distribution rights
-   allows us to do that as long as the file remains unmodified.
-
- - I corrected a few minor things that made the compiler complain when
-   -Wall -pedantic was used.
-
- - I'm moving the official curl web page to http://curl.haxx.nu. I think it
-   will make it easier to remember as it is a lot shorter and less cryptic.
-   The old one still works and shows the same info.
-
- Daniel (11 August 1999)
- - Albert Chin-A-Young mailed me another correction for NROFF in the
-   configure.in that is supposed to be better for IRIX users.
-
- Daniel (10 August 1999)
- - Albert Chin-A-Young helped me with some stupid Makefile things, as well as
-   some fiddling with the getdate.c stuff that he had problems with under
-   HP-UX v10. getdate.y will now be compiled into getdate.c if the appropriate
-   yacc or bison is found by the configure script. Since this is slightly new,
-   we need to test the output getdate.c with win32 systems to make sure it
-   still compiles there.
-
- Daniel (5 August 1999)
- - I've just setup a new mailing list with the intention to keep discussions
-   around libcurl development in it. I mainly expect it to be for thoughts and
-   brainstorming around a "next generation" library, rather than nitpicking
-   about the current implementation or details in the current libcurl.
-
-   To join our happy bunch of future-looking geeks, enter 'subscribe
-   <address>' in the body of a mail and send it to
-   libcurl-request@listserv.fts.frontec.se.  Curl bug reports, the usual curl
-   talk and everything else should still be kept in this mailing list. I've
-   started to archive this mailing list and have put the libcurl web page at
-   www.fts.frontec.se/~dast/libcurl/.
-
- - Stefan Kanthak contacted me regarding a few problems in the configure
-   script which he discovered when trying to make curl compile and build under
-   Siemens SINIX-Z V5.42B2004!
-
- - Marcus Klein very accurately informed me that src/version.h was not present
-   in the CVS repository. Oh, how silly...
-
- - Linus Nielsen rewrote the telnet:// part and now curl offers limited telnet
-   support. If you run curl like 'curl telnet://host' you'll get all output on
-   the screen and curl will read input from stdin. You'll be able to login and
-   run commands etc, but since the output is buffered, expect to get a little
-   weird output.
-
-   This is still in its infancy and it might get changed. We need your
-   feed-back and input in how this is best done.
-
-   WIN32 NOTE: I bet we'll get problems when trying to compile the current
-   lib/telnet.c on win32, but I think we can sort them out in time.
-
- - David Sanderson reported that FORCE_ALLOCA_H or HAVE_ALLOCA_H must be
-   defined for getdate.c to compile properly on HP-UX 11.0. I updated the
-   configure script to check for alloca.h which should make it.
-
- Daniel (4 August 1999)
- - I finally got to understand Marcus Klein's ftp download resume problem,
-   which turns out to be due to different outputs from different ftp
-   servers. It makes ftp download resuming a little trickier, but I've made
-   some modifications I really believe will work for most ftp servers and I do
-   hope you report if you have problems with this!
-
- - Added text about file transfer resuming to README.curl.
-
- Daniel (2 August 1999)
- - Applied a progress-bar patch from Lars J. Aas. It offers
-   a new styled progress bar enabled with -#/--progress-bar. 
-
- T. Yamada <tai at imasy.or.jp> (30 July 1999)
- - It breaks with segfault when 1) curl is using .netrc to obtain
-   username/password (option '-n'), and 2) is automatically redirected to
-   another location (option '-L').
-
-   There is a small bug in lib/url.c (block starting from line 641), which
-   tries to take out username/password from user- supplied command-line
-   argument ('-u' option). This block is never executed on first attempt since
-   CONF_USERPWD bit isn't set at first, but curl later turns it on when it
-   checks for CONF_NETRC bit. So when curl tries to redo everything due to
-   redirection, it segfaults trying to access *data->userpwd.
-
-Version 5.9.1
-
- Daniel (30 July 1999)
- - Steve Walch pointed out that there is a memory leak in the formdata
-   functions. I added a FormFree() function that is now used and supposed to
-   correct this flaw.
-
- - Mark Wotton reported:
-   'curl -L https://www.cwa.com.au/' core dumps.  I managed to cure this by
-   correcting the cleanup procedure. The bug seems to be gone with my OpenSSL
-   0.9.2b, although still occurs when I run the ~100 years old SSLeay 0.8.0. I
-   don't know whether it is curl or SSLeay that is to blame for that.
-
- - Marcus Klein:
-   Reported an FTP upload resume bug that I really can't repeat nor understand.
-   I leave it here so that it won't be forgotten.
-
- Daniel (29 July 1999)
- - Costya Shulyupin suggested support for longer URLs when following Location:
-   and I could only agree and fix it!
-
- - Leigh Purdie found a problem in the upload/POST department. It turned out
-   that http.c accidentaly cleared the pointer instead of the byte counter
-   when supposed to.
-
- - Costya Shulyupin pointed out a problem with port numbers and Location:. If
-   you had a server at a non-standard port that redirected to an URL using a
-   standard port number, curl still used that first port number.
-
- - Ralph Beckmann pointed out a problem when using both CONF_FOLLOWLOCATION
-   and CONF_FAILONERROR simultaneously. Since the CONF_FAILONERROR exits on
-   the 302-code that the follow location header outputs it will never show any
-   html on location: pages. I have now made it look for >=400 codes if
-   CONF_FOLLOWLOCATION is set.
-
- - 'struct slist' is now renamed to 'struct curl_slist' (as suggested by Ralph
-   Beckmann).
-
- - Joshua Swink and Rick Welykochy were the first to point out to me that the
-   latest OpenSSL package now have moved the standard include path. It is now
-   in /usr/local/ssl/include/openssl and I have now modified the --enable-ssl
-   option for the configure script to use that as the primary path, and I
-   leave the former path too to work with older packages of OpenSSL too.
-
- Daniel (9 June 1999)
- - I finally understood the IRIX problem and now it seem to compile on it!
-   I am gonna remove those #define strcasecmp() things once and for all now.
-
- Daniel (4 June 1999)
- - I adjusted the FTP reply 227 parser to make the PASV command work better
-   with more ftp servers. Appearantly the Roxen Challanger server replied
-   something curl 5.9 could deal with! :-( Reported by Ashley Reid-Montanaro
-   and Mark Butler brought a solution for it.
-
- Daniel (26 May 1999)
- - Rearranged. README is new, the old one is now README.curl and I added a
-   README.libcurl with text I got from Ralph Beckmann.
-
- - I also updated the INSTALL text.
-
- Daniel (25 May 1999)
- - David Jonathan Lowsky correctly pointed out that curl didn't properly deal
-   with form posting where the variable shouldn't have any content, as in curl
-   -F "form=" www.site.com. It was now fixed.
-
-Version 5.9
-
- Daniel (22 May 1999)
- - I've got a bug report from Aaron Scarisbrick in which he states he has some
-   problems with -L under FreeBSD 3.0. I have previously got another bug
-   report from Stefan Grether which points at an error with similar sympthoms
-   when using win32. I made the allocation of the new url string a bit faster
-   and different, don't know if it actually improves anything though...
-
- Daniel (20 May 1999)
- - Made the cookie parser deal with CRLF newlines too.
-
- Daniel (19 May 1999)
- - Download() didn't properly deal with failing return codes from the sread()
-   function. Adam Coyne found the problem in the win32 version, and Troy Engel
-   helped me out isolating it.
-
- Daniel (16 May 1999)
- - Richard Adams pointed out a bug I introduced in 5.8. --dump-header doesn't
-   work anymore! :-/ I fixed it now.
-
- - After a suggestion by Joshua Swink I added -S / --show-error to force curl
-   to display the error message in case of an error, even if -s/--silent was
-   used.
-
- Daniel (10 May 1999)
- - I moved the stuff concerning HTTP, DICT and TELNET it their own source
-   files now. It is a beginning on my clean-up of the sources to make them
-   layer all those protocols better to enable more to be added easier in the
-   future!
-
- - Leon Breedt sent me some files I've not put into the main curl
-   archive. They're for creating the Debian package thingie. He also sent me a
-   debian package that I've made available for download at the web page
-
- Daniel (9 May 1999)
- - Made it compile on cygwin too.
-
- Troy Engel (7 May 1999)
- - Brought a series of patches to allow curl to compile smoothly on MSVC++ 6
-   again!

- Daniel (6 May 1999)
- - I changed the #ifdef HAVE_STRFTIME placement for the -z code so that it
-   will be easier to discover systems that don't have that function and thus
-   can't use -z successfully. Made the strftime() get used if WIN32 is defined
-   too.
-
-Version 5.8
-
- Daniel (5 May 1999)
- - I've had it with this autoconf/automake mess. It seems to work allright
-   for most people who don't have automake installed, but for those who have
-   there are problems all over.
-
-   I've got like five different bug reports on this only the last
-   week... Claudio Neves and Federico Bianchi and root <duggerj001 at
-   hawaii.rr.com> are some of them reporting this.
-
-   Currently, I have no really good fix since I want to use automake myself to
-   generate the Makefile.in files. I've found out that the @SHELL@-problems
-   can often be fixed by manually invoking 'automake' in the archive root
-   before you run ./configure... I've hacked my maketgz script now to fiddle
-   a bit with this and my tests seem to work better than before at least!
-
- Daniel (4 May 1999)
- - mkhelp.pl has been doing badly lately. I corrected a case problem in
-   the regexes.
-
- - I've now remade the -o option to not touch the file unless it needs to.
-   I had to do this to make -z option really fine, since now you can make a
-   curl fetch and use a local copy's time when downloading to that file, as
-   in:
-
-        curl -z dump -o dump remote.site.com/file.html
-
-   This will only get the file if the remote one is newer than the local.
-   I'm aware that this alters previous behaviour a little. Some scripts out
-   there may depend on that the file is always touched...
-
- - Corrected a bug in the SSLv2/v3 selection.
-
- - Felix von Leitner requested that curl should be able to send
-   "If-Modified-Since" headers, which indeed is a fair idea.  I implemented it
-   right away! Try -z <expression> where expression is a full GNU date
-   expression or a file name to get the date from!
-
- Stephan Lagerholm (30 Apr 1999)
- - Pointed out a problem with the src/Makefile for FreeBSD. The RM variable
-   isn't set and causes the make to fail.
-
- Daniel (26 April 1999)
- - Am I silly or what? Irving Wolfe pointed out to me that the curl version
-   number was not set properly. Hasn't been since 5.6. This was due to a bug
-   in my maketgz script!
-
- David Eriksson (25 Apr 1999)
- - Found a bug in cookies.c that made it crash at times.
-
-Version 5.7.1
-
- Doug Kaufman (23 Apr 1999)
- - Brought two sunos 4 fixes. One of them being the hostip.c fix mentioned
-   below and the other one a correction in include/stdcheaders.h
-
- - Added a paragraph about compiling with the US-version of openssl to the
-   INSTALL file.
-
- Daniel
- - New mailing list address. Info updated on the web page as well as in the
-   README file
-
- Greg Onufer (20 Apr 1999)
- - hostip.c didn't compile properly on SunOS 5.5.1.
-   It needs an #include <sys/types.h>
-
-Version 5.7
-
- Daniel (Apr 20 1999)
- - Decided to upload a non-beta version right now!
-
- - Made curl support any-length HTTP headers. The destination buffer is now
-   simply enlarged every time it turns out to be too small!
-
- - Added the FAQ file to the archive. Still a bit smallish, but it is a
-   start.
-
- Eric Thelin (15 Apr 1999)
- - Made -D accept '-' instead of filename to write to stdout.
-
-Version 5.6.3beta
-
- Daniel (Apr 12 1999)
-
- - Changed two #ifdef WIN32 to better #ifdef <errorcode> when connect()ing
-   in url.c and ftp.c. Makes cygwin32 deal with them better too. We should
-   try to get some decent win32-replacement there. Anyone?
-
- - The old -3/--crlf option is now ONLY --crlf!
-
- - I changed the "SSL fix" to a more lame one, but that doesn't remove as
-   much functionality. Now I've enabled the lib to select what SSL version it
-   should try first. Appearantly some older SSL-servers don't like when you
-   talk v3 with them so you need to be able to force curl to talk v2 from the
-   start. The fix dated April 6 and posted on the mailing list forced curl to
-   use v2 at all times using a modern OpenSSL version, but we don't really
-   want such a crippled solution.
- 
- - Marc Boucher sent me a patch that corrected a math error for the
-   "Curr.Speed" progress meter.
-
- - Eric Thelin sent me a patch that enables '-K -' to read a config file from
-   stdin.
-
- - I found out we didn't close the file properly before so I added it!
-
- Daniel (Apr 9 1999)
- - Yu Xin pointed out a problem with ftp download resume.  It didn't work at
-   all! ;-O
-
- Daniel (Apr 6 1999)
- - Corrected the version string part generated for the SSL version.
-
- - I found a way to make some other SSL page work with openssl 0.9.1+ that
-   previously didn't (ssleay 0.8.0 works with it though!). Trying to get
-   some real info from the OpenSSL guys to see how I should do to behave the
-   best way. SSLeay 0.8.0 shouldn't be that much in use anyway these days!
-
-Version 5.6.2beta
-
- Daniel (Apr 4 1999)
- - Finally have curl more cookie "aware". Now read carefully. This is how
-   it works.
-   To make curl read cookies from an already existing file, in plain header-
-   format (like from the headers of a previous fetch) invoke curl with the
-   -b flag like:
-
-        curl -b file http://site/foo.html
-
-   Curl will then use all cookies it finds matching. The old style that sets
-   a single cookie with -b is still supported and is used if the string
-   following -b includes a '=' letter, as in "-b name=daniel".
-
-   To make curl read the cookies sent in combination with a location: (which
-   sites often do) point curl to read a non-existing file at first (i.e
-   to start with no existing cookies), like:
-
-        curl -b nowhere http://site/setcookieandrelocate.html
-
- - Added a paragraph in the TODO file about the SSL problems recently
-   reported. Evidently, some kind of SSL-problem curl may need to address.
-
- - Better "Location:" following.
-
- Douglas E. Wegscheid (Tue, 30 Mar 1999)
- - A subsecond display patch.
-
- Daniel (Mar 14 1999)
- - I've separated the version number of libcurl and curl now. To make
-   things a little easier, I decided to start the curl numbering from
-   5.6 and the former version number known as "curl" is now the one
-   set for libcurl.
-
- - Removed the 'enable-no-pass' from configure, I doubt anyone wanted
-   that.
-
- - Made lots of tiny adjustments to compile smoothly with cygwin under
-   win32. It's a killer for porting this to win32, bye bye VC++! ;-)
-   Compiles and builds out-of-the-box now. See the new wordings in
-   INSTALL for details.
-
- - Beginning experiments with downloading multiple document from a http
-   server while remaining connected.
-
-Version 5.6beta
-
- Daniel (Mar 13 1999)
- - Since I've changed so much, I thought I'd just go ahead and implement the
-   suggestion from Douglas E. Wegscheid. -D or --dump-header is now storing
-   HTTP headers separately in the specified file.
-
- - Added new text to INSTALL on what to do to build this on win32 now.
-
- - Aaargh. I had to take a step back and prefix the shared #include files
-   in the sources with "../include/" to please VC++...
-
- Daniel (Mar 12 1999)
- - Split the url.c source into many tiny sources for better readability
-   and smaller size.
-
- Daniel (Mar 11 1999)
- - Started to change stuff for a move to make libcurl and a more separate
-   curl application that uses the libcurl. Made the libcurl sources into
-   the new lib directory while the curl application will remain in src as
-   before. New makefiles, adjusted configure script and so.
-
-   libcurl.a built quickly and easily. I better make a better interface to
-   the lib functions though.
-
-   The new root dir include/ is supposed to contain the public information
-   about the new libcurl. It is a little ugly so far :-)
-
-
- Daniel (Mar 1 1999)
- - Todd Kaufmann sent me a good link to Netscape's cookie spec as well as the
-   info that RFC 2109 specifies how to use them.  The link is now in the
-   README and the RFC in the RESOURCES.
-
- Daniel (Feb 23 1999)
- - Finally made configure accept --with-ssl to look for SSL libs and includes
-   in the "standard" place /usr/local/ssl...
-
- Daniel (Feb 22 1999)
- - Verified that curl linked fine with OpenSSL 0.9.1c which seems to be
-   the most recent.
-
- Henri Gomez (Fri Feb  5 1999)
- - Sent in an updated curl-ssl.spec. I still miss the script that builds an
-   RPM automatically...
-
-Version 5.5.1
-
- Mark Butler (27 Jan 1999)
- - Corrected problems in Download().
-
- Danitel Stenberg (25 Jan 1999)
- - Jeremie Petit pointed out a few flaws in the source that prevented it from
-   compile warning free with the native compiler under Digital Unix v4.0d.
-
-Version 5.5
-
- Daniel Stenberg (15 Jan 1999)
- - Added Bjorns small text to the README about the DICT protocol.
-
- Daniel Stenberg (11 Jan 1999)
- - <jswink at softcom.net> reported about the win32-versioin: "Doesn't use
-   ALL_PROXY environment variable". Turned out to be because of the static-
-   buffer nature of the win32 environment variable calls!
-
- Bjorn Reese (10 Jan 1999)
- - I have attached a simple addition for the DICT protocol (RFC 2229).
-   It performs dictionary lookups. The output still needs to be better
-   formatted.
-
-   To test it try (the exact format, and more examples are described in
-   the RFC)
-
-        dict://dict.org/m:hello
-        dict://dict.org/m:hello::soundex
-
-
- Vicente Garcia (10 Jan 1999)
- - Corrected the progress meter for files larger than 20MB.
-
- Daniel Stenberg (7 Jan 1999)
- - Corrected the -t and -T help texts. They claimed to be FTP only.
-
-Version 5.4
-
- Daniel Stenberg
- (7 Jan 1999)
- - Irving Wolfe reported that curl -s didn't always supress the progress
-   reporting. It was the form post that autoamtically always switched it on
-   again. This is now corrected!
-
- (4 Jan 1999)
- - Andreas Kostyrka suggested I'd add PUT and he helped me out to test it. If
-   you use -t or -T now on a http or https server, PUT will be used for file
-   upload.
-
-   I removed the former use of -T with HTTP. I doubt anyone ever really used
-   that.
-
- (4 Jan 1999)
- - Erik Jacobsen found a width bug in the mprintf() function.  I corrected it
-   now.
-
- (4 Jan 1999)
- - As John V. Chow pointed out to me, curl accepted very limited URL sizes. It
-   should now accept path parts that are up to at least 4096 bytes.
-
- - Somehow I screwed up when applying the AIX fix from Gilbert Ramirez, so
-   I redid that now.

 This release includes the following changes:
  
- o Support for SCP and SFTP were added (powered by libssh2)
- o CURLOPT_CLOSEPOLICY is now deprecated
- o --ftp-ssl-ccc and CURLOPT_FTP_SSL_CCC were added
- o HTTP support for non-ASCII platforms
- o --libcurl was added
+ o support for OS/400 Secure Sockets Layer library
+ o curl_easy_setopt() now allocates strings passed to it
+ o SCP and SFTP support now requires libssh2 0.16 or later
+ o LDAP libraries are now linked "regularly" and not with dlopen
+ o HTTP transfers have the download size info "available" earlier
+ o FTP transfers have the download size info "available" earlier
+ o builds and runs on OS/400
+ o several error codes and options were marked as obsolete and subject to
+   future removal (set CURL_NO_OLDIES to see if your application is using them)
+ o SFTP errors can return more specific error codes 
 
 This release includes the following bugfixes:
 
- o proxy close during CONNECT authentication is now dealt with nicely
- o the CURLOPT_DEBUGFUNCTION was sometimes called even when CURLOPT_VERBOSE
-   was not enabled
- o multiple TFTP transfers on the same (easy or multi) handle could cause a
-   crash
- o SIGSEGV when disconnecting on a transfer on a re-used handle when the
-   host name didn't resolve
- o stack overwrite on 64bit Windows in the chunked decoding department
- o HTTP responses on persistent connections without Content-Length nor chunked
-   encoding are now considered to be without response body
- o Content-Range: header parsing improved
- o CPU 100% load when HTTP upload connection broke
- o active FTP didn't work with multi interface
- o curl_getdate() could be off one hour for TZ time zones with DST, on windows
- o CURLOPT_FORBID_REUSE works again
- o CURLOPT_MAXCONNECTS set to zero caused libcurl to SIGSEGV
- o rate limiting works better
- o getting FTP response code errors when using the multi-interface caused
-   libcurl to leak memory
- o no more SIGPIPE when GnuTLS is used
- o FTP downloading 2 zero byte files in a row
- o using proxy and URLs without protocol prefixes
- o first using a proxy and then accessing a site that 'no_proxy' matched,
-   would still make libcurl use the proxy...
- o curl_easy_duphandle() now makes a handle that is valid for the multi
-   interface since the magic number is set fine

- o CURLOPT_COOKIELIST set to "ALL" crash
- o easy handle removal from multi handle before completion
- o TFTP upload memory leak
- o curl_easy_reset() now resets the CA bundle path correctly
- o two User-Agent headers in CONNECT requests with custom User-Agent

   Changelog for the c-ares project
 
-* November 22
+* July 14 2007 (Daniel Stenberg)
+
+- Vlad Dinulescu fixed two outstanding valgrind reports:
+
+ 
+  1. In ares_query.c , in find_query_by_id we compare q->qid (which is a short
+  int variable) with qid, which is declared as an int variable.  Moreover,
+  DNS_HEADER_SET_QID is used to set the value of qid, but DNS_HEADER_SET_QID
+  sets only the first two bytes of qid. I think that qid should be declared as
+  "unsigned short" in this function.
+
+  2. The same problem occurs in ares_process.c, process_answer() .  query->qid
+  (an unsigned short integer variable) is compared with id, which is an
+  integer variable. Moreover, id is initialized from DNS_HEADER_QID which sets
+  only the first two bytes of id. I think that the id variable should be
+  declared as "unsigned short" in this function.
+
+  Even after declaring these variables as "unsigned short", the valgrind
+  errors are still there. Which brings us to the third problem.
+
+  3. The third problem is that Valgrind assumes that query->qid is not
+  initialised correctly. And it does that because query->qid is set from
+  DNS_HEADER_QID(qbuf); Valgrind says that qbuf has unitialised bytes. And
+  qbuf has uninitialised bytes because of channel->next_id . And next_id is
+  set by ares_init.c:ares__generate_new_id() . I found that putting short r=0
+  in this function (instead of short r) makes all Valgrind warnings go away.
+  I have studied ares__rc4() too, and this is the offending line:
+
+        buffer_ptr[counter] ^= state[xorIndex];   (ares_query.c:62)
+
+  This is what triggers Valgrind.. buffer_ptr is unitialised in this function,
+  and by applying ^= on it, it remains unitialised.
+
+Version 1.4.0 (June 8, 2007)
+
+* June 4 2007 (Daniel Stenberg)
+
+- James Bursa reported a major memory problem when resolving multi-IP names
+  and I found and fixed the problem. It was added by Ashish Sharma's patch
+  two days ago.
+
+  When I then tried to verify multiple entries in /etc/hosts after my fix, I
+  got another segfault and decided this code was not ripe for inclusion and I
+  reverted the patch.
+
+* June 2 2007
+
+- Brad Spencer found and fixed three flaws in the code, found with the new
+  gcc 4.2.0 warning: -Waddress
+
+- Brad House fixed VS2005 compiler warnings due to time_t being 64bit.
+  He also made recent Microsoft compilers use _strdup() instead of strdup().
+
+- Brad House's man pages for ares_save_options() and ares_destroy_options()
+  were added.
+
+- Ashish Sharma provided a patch for supporting multiple entries in the
+  /etc/hosts file. Patch edited for coding style and functionality by me
+  (Daniel).
+
+* May 30 2007
+
+- Shmulik Regev brought cryptographically secure transaction IDs:
+
+  The c-ares library implementation uses a DNS "Transaction ID" field that is
+  seeded with a pseudo random number (based on gettimeofday) which is
+  incremented (++) between consecutive calls and is therefore rather
+  predictable. In general, predictability of DNS Transaction ID is a well
+  known security problem (e.g.
+  http://bak.spc.org/dms/archive/dns_id_attack.txt) and makes a c-ares based
+  implementation vulnerable to DNS poisoning. Credit goes to Amit Klein
+  (Trusteer) for identifying this problem.
+
+  The patch I wrote changes the implementation to use a more secure way of
+  generating unique IDs. It starts by obtaining a key with reasonable entropy
+  which is used with an RC4 stream to generate the cryptographically secure
+  transaction IDs.
+
+  Note that the key generation code (in ares_init:randomize_key) has two
+  versions, the Windows specific one uses a cryptographically safe function
+  provided (but undocumented :) by the operating system (described at
+  http://blogs.msdn.com/michael_howard/archive/2005/01/14/353379.aspx).  The
+  default implementation is a bit naive and uses the standard 'rand'
+  function. Surely a better way to generate random keys exists for other
+  platforms.
+
+  The patch can be tested by using the adig utility and using the '-s' option.
+
+- Brad House added ares_save_options() and ares_destroy_options() that can be
+  used to keep options for later re-usal when ares_init_options() is used.
+  
+  Problem: Calling ares_init() for each lookup can be unnecessarily resource
+         intensive.  On windows, it must LoadLibrary() or search the registry
+         on each call to ares_init().  On unix, it must read and parse
+         multiple files to obtain the necessary configuration information.  In
+         a single-threaded environment, it would make sense to only
+         ares_init() once, but in a heavily multi-threaded environment, it is
+         undesirable to ares_init() and ares_destroy() for each thread created
+         and track that.
+
+  Solution: Create ares_save_options() and ares_destroy_options() functions to
+         retrieve and free options obtained from an initialized channel.  The
+         options populated can be used to pass back into ares_init_options(),
+         it should populate all needed fields and not retrieve any information
+         from the system.  Probably wise to destroy the cache every minute or
+         so to prevent the data from becoming stale.
+
+- Daniel S added ares_process_fd() to allow applications to ask for processing
+  on specific sockets and thus avoiding select() and associated
+  functions/macros.  This function will be used by upcoming libcurl releases
+  for this very reason. It also made me export the ares_socket_t type in the
+  public ares.h header file, since ares_process_fd() uses that type for two of
+  the arguments.
+
+* May 25 2007
+
+- Ravi Pratap fixed a flaw in the init_by_resolv_conf() function for windows
+  that could cause it to return a bad return code.
+
+* April 16 2007
+
+- Yang Tse: Provide ares_getopt() command-line parser function as a source
+  code helper function, not belonging to the actual c-ares library.
+
+* February 19 2007
+
+- Vlad Dinulescu added ares_parse_ns_reply().
+
+* February 13 2007
+
+- Yang Tse: Fix failure to get the search sequence of /etc/hosts and
+  DNS from /etc/nsswitch.conf, /etc/host.conf or /etc/svc.conf when
+  /etc/resolv.conf did not exist or was unable to read it.

+.TH ARES_PARSE_NS_REPLY 3 "10 February 2007"
+.SH NAME
+ares_parse_ns_reply \- Parse a reply to a DNS query of type NS into a hostent
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_parse_ns_reply(const unsigned char *\fIabuf\fP, int \fIalen\fP,
+.B 	struct hostent **\fIhost\fP);
+.fi
+.SH DESCRIPTION
+The
+.B ares_parse_ns_reply
+function parses the response to a query of type NS into a
+.BR "struct hostent" .
+The parameters
+.I abuf
+and
+.I alen
+give the contents of the response.  The result is stored in allocated
+memory and a pointer to it stored into the variable pointed to by
+.IR host . 
+The nameservers are stored into the 
+.BR aliases 
+field of the 
+.IR host 
+structure. 
+It is the caller's responsibility to free the resulting host structure
+using
+.BR ares_free_hostent (3)
+when it is no longer needed.
+.SH RETURN VALUES
+.B ares_parse_ns_reply
+can return any of the following values:
+.TP 15
+.B ARES_SUCCESS
+The response was successfully parsed.
+.TP 15
+.B ARES_EBADRESP
+The response was malformatted.
+.TP 15
+.B ARES_ENODATA
+The response did not contain an answer to the query.
+.TP 15
+.B ARES_ENOMEM
+Memory was exhausted.
+.SH SEE ALSO
+.BR ares_query (3),
+.BR ares_free_hostent (3)

+.SH NAME
+ares_save_options \- Save configuration values obtained from initialized ares_channel
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B void ares_save_options(ares_channel \fIchannel\fP, struct ares_options *\fIoptions\fP, int *\fIoptmask\fP)
+.fi
+.SH DESCRIPTION
+The
+.B ares_save_options
+function saves the channel data identified by
+.IR channel ,
+into the options struct identified by
+.IR options ,
+and saves the mask of options which are set to the integer
+pointer (passed by reference) identified by
+.IR optmask .
+
+The resultant options and optmask are then able to be
+passed directly to ares_init_options.  When the options
+are no longer needed, ares_destroy_options should be called
+to free any associated memory.

-Fixing the Only Problem
-
- The only problem is thus for distributions that want to offer libcurl
- versions built with more than one SSL/TLS library.
-
- Since multiple libcurl binaries using different names are ruled out, we need
- to come up with a way to have one single libcurl that someone uses different
- underlying libraries. The best(?) approach currently suggested involves this:
-
- A new intermediate library (named lib2 so far in the discussions) with the
- single purpose of providing libcurl with SSL/TLS capabilities. It would have
- a unified API and ABI no matter what underlying library it would use.
-
- There would be one lib2 binary provided for each supported SSL/TLS library.
- For example: lib2-openssl, lib2-gnutls, lib2-yassl, lib2-matrixssl and
- lib2-nossl. Yes, take note of the last one that provides the lib2 ABI but
- that lacks the actual powers.
-
- When libcurl is built and linked, it will be linked against a lib2 with the
- set ABI.
-
- When you link an app against libcurl, it would also need to provide one of
- the (many) lib2 libs to decide what approach that fits the app. An app that
- doesn't want SSL at all would still need to link with the lib2-nossl lib.
-
- GPL apps can pick the lib2-gnutls, others may pick the lib2-openssl.
-
- This concept works equally well both for shared and static libraries.
-
- A positive side effect of this approach could be a more generic "de facto"
- standard API for SSL/TLS libraries.
-
-When Will This Happen
-
- This is not a problem in curl, it doesn't solve any actual technical problems
- in our project. Don't hold your breath for this to happen very soon (if at
- all) unless you step forward and contribute.
-
- The suggestion that is outlined above is still only a suggestion. Feel free
- to bring a better idea!
-
- Also, to keep in mind: I don't want this new concept to have too much of an
- impact on the existing code. Preferably it should be possible to build the
- code like today (without the use of lib2), should you decide to ignore the
- problems outlined in this document.

+  4.15 FTPS doesn't work
+
+  curl supports FTPS (sometimes known as FTP-SSL) both implicit and explicit
+  mode.
+
+  When a URL is used that starts with FTPS://, curl assumes implicit SSL on
+  the control connection and will therefore immediately connect and try to
+  speak SSL. FTPS:// connections default to port 990.
+
+  To use explicit FTPS, you use a FTP:// URL and the --ftp-ssl option (or one
+  of its related flavours). This is the most common method, and the one
+  mandated by RFC4217. This kind of connection then of course uses the
+  standard FTP port 21 by default.
