+Version 7.16.1 (29 January 2007)
+
+Daniel (29 January 2007)
+- Michael Wallner reported that when doing a CONNECT with a custom User-Agent
+  header, you got _two_ User-Agent headers in the CONNECT request...! Added
+  test case 287 to verify the fix.
+
+Daniel (28 January 2007)
+- curl_easy_reset() now resets the CA bundle path correctly.
+
+- David McCreedy fixed the Curl command line tool for HTTP on non-ASCII
+  platforms.
+
+Daniel (25 January 2007)
+- Added the --libcurl [file] option to curl. Append this option to any
+  ordinary curl command line, and you will get a libcurl-using source code
+  written to the file that does the equivalent operation of what your command
+  line operation does!
+
+Dan F (24 January 2007)
+- Fixed a dangling pointer problem that prevented the http_proxy environment
+  variable from being properly used in many cases (and caused test case 63
+  to fail).
+
+Daniel (23 January 2007)
+- David McCreedy did NTLM changes mainly for non-ASCII platforms:
+
+  #1
+  There's a compilation error in http_ntlm.c if USE_NTLM2SESSION is NOT
+  defined.  I noticed this while testing various configurations.  Line 867 of
+  the current http_ntlm.c is a closing bracket for an if/else pair that only
+  gets compiled in if USE_NTLM2SESSION is defined.  But this closing bracket
+  wasn't in an #ifdef so the code fails to compile unless USE_NTLM2SESSION was
+  defined.  Lines 198 and 140 of my patch wraps that closing bracket in an
+  #ifdef USE_NTLM2SESSION.
+
+  #2
+  I noticed several picky compiler warnings when DEBUG_ME is defined.  I've
+  fixed them with casting.  By the way, DEBUG_ME was a huge help in
+  understanding this code.
+
+  #3
+  Hopefully the last non-ASCII conversion patch for libcurl in a while.  I
+  changed the "NTLMSSP" literal to hex since this signature must always be in
+  ASCII.
+
+  Conversion code was strategically added where necessary.  And the
+  Curl_base64_encode calls were changed so the binary "blobs" http_ntlm.c
+  creates are NOT translated on non-ASCII platforms.
+
+Dan F (22 January 2007)
+- Converted (most of) the test data files into genuine XML.  A handful still
+  are not, due mainly to the lack of support for XML character entities
+  (e.g. & => & ).  This will make it easier to validate test files using
+  tools like xmllint, as well as to edit and view them using XML tools.
+
+Daniel (16 January 2007)
+- Armel Asselin improved libcurl to behave a lot better when an easy handle
+  doing an FTP transfer is removed from a multi handle before completion. The
+  fix also fixed the "alive counter" to be correct on "premature removal" for
+  all protocols.
+
+Dan F (16 January 2007)
+- Fixed a small memory leak in tftp uploads discovered by curl's memory leak
+  detector.  Also changed tftp downloads to URL-unescape the downloaded
+  file name.
+
+Daniel (14 January 2007)
+- David McCreedy provided libcurl changes for doing HTTP communication on
+  non-ASCII platforms. It does add some complexity, most notably with more
+  #ifdefs, but I want to see this supported added and I can't see how we can
+  add it without the extra stuff added.
+
+- Setting CURLOPT_COOKIELIST to "ALL" when no cookies at all was present,
+  libcurl would crash when trying to read a NULL pointer.
+
+Daniel (12 January 2007)
+- Toby Peterson found a nasty bug that prevented (lib)curl from properly
+  downloading (most) things that were larger than 4GB on 32 bit systems.  Matt
+  Witherspoon helped as narrow down the problem.
+
+Daniel (5 January 2007)
+- Linus Nielsen Feltzing introduced the --ftp-ssl-ccc command line option to
+  curl that uses the new CURLOPT_FTP_SSL_CCC option in libcurl. If enabled, it
+  will make libcurl shutdown SSL/TLS after the authentication is done on a
+  FTP-SSL operation.
+
+Daniel (4 January 2007)
+- David McCreedy made changes to allow base64 encoding/decoding to work on
+  non-ASCII platforms.
+
+Daniel (3 January 2007)
+- Matt Witherspoon fixed the flaw which made libcurl 7.16.0 always store
+  downloaded data in two buffers, just to be able to deal with a special HTTP
+  pipelining case. That is now only activated for pipelined transfers. In
+  Matt's case, it showed as a considerable performance difference,
+
+Daniel (2 January 2007)
+- Victor Snezhko helped us fix bug report #1603712
+  (http://curl.haxx.se/bug/view.cgi?id=1603712) (known bug #36) --limit-rate
+  (CURLOPT_MAX_SEND_SPEED_LARGE and CURLOPT_MAX_RECV_SPEED_LARGE) are broken
+  on Windows (since 7.16.0, but that's when they were introduced as previous
+  to that the limiting logic was made in the application only and not in the
+  library). It was actually also broken on select()-based systems (as apposed
+  to poll()) but we haven't had any such reports. We now use select(), Sleep()
+  or delay() properly to sleep a while without waiting for anything input or
+  output when the rate limiting is activated with the easy interface.
+
+- Modified libcurl.pc.in to use Libs.private for the libs libcurl itself needs
+  to get built static. It has been mentioned before and was again brought to
+  our attention by Nathanael Nerode who filed debian bug report #405226
+  (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=405226).
+
+Daniel (29 December 2006)
+- Make curl_easy_duphandle() set the magic number in the new handle.
+
+Daniel (22 December 2006)
+- Robert Foreman provided a prime example snippet showing how libcurl would
+  get confused and not acknowledge the 'no_proxy' variable properly once it
+  had used the proxy and you re-used the same easy handle. I made sure the
+  proxy name is properly stored in the connect struct rather than the
+  sessionhandle/easy struct.
+
+- David McCreedy fixed a bad call to getsockname() that wrongly used a size_t
+  variable to point to when it should be a socklen_t.
+
+- When setting a proxy with environment variables and (for example) running
+  'curl [URL]' with a URL without a protocol prefix, curl would not send a
+  correct request as it failed to add the protocol prefix.
+
+Daniel (21 December 2006)
+- Robson Braga Araujo reported bug #1618359
+  (http://curl.haxx.se/bug/view.cgi?id=1618359) and subsequently provided a
+  patch for it: when downloading 2 zero byte files in a row, curl 7.16.0
+  enters an infinite loop, while curl 7.16.1-20061218 does one additional
+  unnecessary request.
+
+  Fix: During the "Major overhaul introducing http pipelining support and
+  shared connection cache within the multi handle." change, headerbytecount
+  was moved to live in the Curl_transfer_keeper structure. But that structure
+  is reset in the Transfer method, losing the information that we had about
+  the header size. This patch moves it back to the connectdata struct.
+
+Daniel (16 December 2006)
+- Brendan Jurd provided a fix that now prevents libcurl from getting a SIGPIPE
+  during certain conditions when GnuTLS is used.
+
+Daniel (11 December 2006)
+- Alexey Simak found out that when doing FTP with the multi interface and
+  something went wrong like it got a bad response code back from the server,
+  libcurl would leak memory. Added test case 538 to verify the fix.
+
+  I also noted that the connection would get cached in that case, which
+  doesn't make sense since it cannot be re-use when the authentication has
+  failed. I fixed that issue too at the same time, and also that the path
+  would be "remembered" in vain for cases where the connection was about to
+  get closed.
+
+Daniel (6 December 2006)
+- Sebastien Willemijns reported bug #1603712
+  (http://curl.haxx.se/bug/view.cgi?id=1603712) which is about connections
+  getting cut off prematurely when --limit-rate is used. While I found no such
+  problems in my tests nor in my reading of the code, I found that the
+  --limit-rate code was severly flawed (since it was moved into the lib, since
+  7.15.5) when used with the easy interface and it didn't work as documented
+  so I reworked it somewhat and now it works for my tests.
+
+Daniel (5 December 2006)
+- Stefan Krause pointed out a compiler warning with a picky MSCV compiler when
+  passing a curl_off_t argument to the Curl_read_rewind() function which takes
+  an size_t argument. Curl_read_rewind() also had debug code left in it and it
+  was put in a different source file with no good reason when only used from
+  one single spot.
+
+- Sh Diao reported that CURLOPT_CLOSEPOLICY doesn't work, and indeed, there is
+  no code present in the library that receives the option. Since it was not
+  possible to use, we know that no current users exist and thus we simply
+  removed it from the docs and made the code always use the default path of
+  the code.
+
+- Jared Lundell filed bug report #1604956
+  (http://curl.haxx.se/bug/view.cgi?id=1604956) which identified setting
+  CURLOPT_MAXCONNECTS to zero caused libcurl to SIGSEGV. Starting now, libcurl
+  will always internally use no less than 1 entry in the connection cache.
+
+- Sh Diao reported that CURLOPT_FORBID_REUSE no works, and indeed it broke in
+  the 7.16.0 release.
+
+- Martin Skinner brought back bug report #1230118 to haunt us once again.
+  (http://curl.haxx.se/bug/view.cgi?id=1230118) curl_getdate() did not work
+  properly for all input dates on Windows. It was mostly seen on some TZ time
+  zones using DST. Luckily, Martin also provided a fix.
+
+- Alexey Simak filed bug report #1600447
+  (http://curl.haxx.se/bug/view.cgi?id=1600447) in which he noted that active
+  FTP connections don't work with the multi interface. The problem is here
+  that the multi interface state machine has a state during which it can wait
+  for the data connection to connect, but the active connection is not done in
+  the same step in the sequence as the passive one is so it doesn't quite work
+  for active. The active FTP code still use a blocking function to allow the
+  remote server to connect.
+
+  The fix (work-around is a better word) for this problem is to set the
+  boolean prematurely that the data connection is completed, so that the "wait
+  for connect" phase ends at once.
+
+  The proper fix, left for the future, is of course to make the active FTP
+  case to act in a non-blocking way too.
+
+- Matt Witherspoon fixed a problem case when the CPU load went to 100% when a
+  HTTP upload was disconnected:
+
+  "What appears to be happening is that my system (Linux 2.6.17 and 2.6.13) is
+  setting *only* POLLHUP on poll() when the conditions in my previous mail
+  occur. As you can see, select.c:Curl_select() does not check for POLLHUP. So
+  basically what was happening, is poll() was returning immediately (with
+  POLLHUP set), but when Curl_select() looked at the bits, neither POLLERR or
+  POLLOUT was set. This still caused Curl_readwrite() to be called, which
+  quickly returned. Then the transfer() loop kept continuing at full speed
+  forever."
+
+Daniel (1 December 2006)
+- Toon Verwaest reported that there are servers that send the Content-Range:
+  header in a third, not suppported by libcurl, format and we agreed that we
+  could make the parser more forgiving to accept all the three found
+  variations.
+
+Daniel (25 November 2006)
+- Venkat Akella found out that libcurl did not like HTTP responses that simply
+  responded with a single status line and no headers nor body. Starting now, a
+  HTTP response on a persistent connection (i.e not set to be closed after the
+  response has been taken care of) must have Content-Length or chunked
+  encoding set, or libcurl will simply assume that there is no body.
+
+  To my horror I learned that we had no less than 57(!) test cases that did bad
+  HTTP responses like this, and even the test http server (sws) responded badly
+  when queried by the test system if it is the test system. So although the
+  actual fix for the problem was tiny, going through all the newly failing test
+  cases got really painful and boring.
+
+Daniel (24 November 2006)
+- James Housley did lots of work and introduced SFTP downloads.
+
+Daniel (13 November 2006)
+- Ron in bug #1595348 (http://curl.haxx.se/bug/view.cgi?id=1595348) pointed
+  out a stack overwrite (and the corresponding fix) on 64bit Windows when
+  dealing with HTTP chunked encoding.
+
+Daniel (9 November 2006)
+- Nir Soffer updated libcurl.framework.make:
+  o fix symlinks, should link to Versions, not to ./Versions
+  o indentation improvments
+
+- Dmitriy Sergeyev found a SIGSEGV with his test04.c example posted on 7 Nov
+  2006. It turned out we wrongly assumed that the connection cache was present
+  when tearing down a connection.
+
+- Ciprian Badescu found a SIGSEGV when doing multiple TFTP transfers using the
+  multi interface, but I could also repeat it doing multiple sequential ones
+  with the easy interface. Using Ciprian's test case, I could fix it.
+
+Daniel (8 November 2006)
+- Bradford Bruce reported that when setting CURLOPT_DEBUGFUNCTION without
+  CURLOPT_VERBOSE set to non-zero, you still got a few debug messages from the
+  SSL handshake. This is now stopped.
+
+Daniel (7 November 2006)
+- Olaf fixed a leftover problem with the CONNECT fix of his that would leave a
+  wrong error message in the error message buffer.
+
+Daniel (3 November 2006)
+- Olaf Stueben provided a patch that I edited slightly. It fixes the notorious
+  KNOWN_BUGS #25, which happens when a proxy closes the connection when
+  libcurl has sent CONNECT, as part of an authentication negotiation. Starting
+  now, libcurl will re-connect accordingly and continue the authentication as
+  it should.
+
+Daniel (2 November 2006)
+- James Housley brought support for SCP transfers, based on the libssh2 library
+  for the actual network protocol stuff.
+
+  Added these new curl_easy_setopt() options:
+
+    CURLOPT_SSH_AUTH_TYPES
+    CURLOPT_SSH_PUBLIC_KEYFILE
+    CURLOPT_SSH_PRIVATE_KEYFILE
+
+Version 7.16.0 (30 October 2006)
+
+Daniel (25 October 2006)
+- Fixed CURLOPT_FAILONERROR to return CURLE_HTTP_RETURNED_ERROR even for the
+  case when 401 or 407 are returned, *IF* no auth credentials have been given.
+  The CURLOPT_FAILONERROR option is not possible to make fool-proof for 401
+  and 407 cases when auth credentials is given, but we've now covered this
+  somewhat more.
+
+  You might get some amounts of headers transferred before this situation is
+  detected, like for when a "100-continue" is received as a response to a
+  POST/PUT and a 401 or 407 is received immediately afterwards.
+
+  Added test 281 to verify this change.
+
+Daniel (23 October 2006)
+- Ravi Pratap provided a major update with pipelining fixes. We also no longer
+  re-use connections (for pipelining) before the name resolving is done.
+
+Daniel (21 October 2006)
+- Nir Soffer made the tests/libtest/Makefile.am use a proper variable for all
+  the single test applications' link and dependences, so that you easier can
+  override those from the command line when using make.
+
+- Armel Asselin separated CA cert verification problems from problems with
+  reading the (local) CA cert file to let users easier pinpoint the actual
+  problem. CURLE_SSL_CACERT_BADFILE (77) is the new libcurl error code.
+
+Daniel (18 October 2006)
+- Removed the "protocol-guessing" for URLs with host names starting with FTPS
+  or TELNET since they are practically non-existant. This leaves us with only
+  three different prefixes that would assume the protocol is anything but
+  HTTP, and they are host names starting with "ftp.", "dict." or "ldap.".
+
+Daniel (17 October 2006)
+- Bug report #1579171 pointed out code flaws detected with "prefast", and they
+  were 1 - a too small memory clear with memset() in the threaded resolver and
+  2 - a range of potentially bad uses of the ctype family of is*() functions
+  such as isdigit(), isalnum(), isprint() and more. The latter made me switch
+  to using our own set of these functions/macros using uppercase letters, and
+  with some extra set of crazy typecasts to avoid mistakingly passing in
+  negative numbers to the underlying is*() functions.
+
+- With Jeff Pohlmeyer's help, I fixed the expire timer when using
+  curl_multi_socket() during name resolves with c-ares and the LOW_SPEED
+  options now work fine with curl_multi_socket() as well.
+
+Daniel (16 October 2006)
+- Added a check in configure that simply tries to run a program (not when
+  cross-compiling) in order to detect problems with run-time libraries that
+  otherwise would occur when the sizeof tests for curl_off_t would run and
+  thus be much more confusing to users. The check of course should run after
+  all lib-checks are done and before any other test is used that would run an
+  executable built for testing-purposes.
+
+Dan F (13 October 2006)
+- The tagging of application/x-www-form-urlencoded POST body data sent
+  to the CURLOPT_DEBUGFUNCTION callback has been fixed (it was erroneously
+  included as part of the header).  A message was also added to the
+  command line tool to show when data is being sent, enabled when
+  --verbose is used.
+
+Daniel (12 October 2006)
+- Starting now, adding an easy handle to a multi stack that was already added
+  to a multi stack will cause CURLM_BAD_EASY_HANDLE to get returned.
+
+- Jeff Pohlmeyer has been working with the hiperfifo.c example source code,
+  and while doing so it became apparent that the current timeout system for
+  the socket API really was a bit awkward since it become quite some work to
+  be sure we have the correct timeout set.
+
+  Jeff then provided the new CURLMOPT_TIMERFUNCTION that is yet another
+  callback the app can set to get to know when the general timeout time
+  changes and thus for an application like hiperfifo.c it makes everything a
+  lot easier and nicer. There's a CURLMOPT_TIMERDATA option too of course in
+  good old libcurl tradition.
+
+  Jeff has also updated the hiperfifo.c example code to use this news.
+
+Daniel (9 October 2006)
+- Bogdan Nicula's second test case (posted Sun, 08 Oct 2006) converted to test
+  case 535 and it now runs fine. Again a problem with the pipelining code not
+  taking all possible (error) conditions into account.
+
+Daniel (6 October 2006)
+- Bogdan Nicula's hanging test case (posted Wed, 04 Oct 2006) was converted to
+  test case 533 and the test now runs fine.
+
+Daniel (4 October 2006)
+- Dmitriy Sergeyev provided an example source code that crashed CVS libcurl
+  but that worked nicely in 7.15.5. I converted it into test case 532 and
+  fixed the problem.
+
+Daniel (29 September 2006)
+- Removed a few other no-longer present options from the header file.
+
+- Support for FTP third party transfers was removed. Here's why:
+
+  o The recent multi interface changes broke it and the design of the 3rd party
+    transfers made it very hard to fix the problems
+  o It was still blocking and thus nasty for the multi interface
+  o It was a lot of extra code for a very rarely used feature
+  o It didn't use the same code as for "plain" FTP transfers, so it didn't work
+    fine for IPv6 and it didn't properly re-use connections and more
+  o There's nobody around who's willing to work on and improve the existing
+    code
+
+  This does not mean that third party transfers are banned forever, only that
+  they need to be done better if they are to be re-added in the future.
+
+  The CURLOPT_SOURCE_* options are removed from the lib and so are the --3p*
+  options from the command line tool. For this reason, I also bumped the
+  version info for the lib.
+
+Daniel (28 September 2006)
+- Reported in #1561470 (http://curl.haxx.se/bug/view.cgi?id=1561470), libcurl
+  would crash if a bad function sequence was used when shutting down after
+  using the multi interface (i.e using easy_cleanup after multi_cleanup) so
+  precautions have been added to make sure it doesn't any more - test case 529
+  was added to verify.
+
+Daniel (27 September 2006)
+- The URL in the cookie jar file is now changed since it was giving a 404.
+  Reported by Timothy Stone. The new URL will take the visitor to a curl web
+  site mirror with the document.
+
+Daniel (24 September 2006)
+- Bernard Leak fixed configure --with-gssapi-libs.
+
+- Cory Nelson made libcurl use the WSAPoll() function if built for Windows
+  Vista (_WIN32_WINNT >= 0x0600)
+
+Daniel (23 September 2006)
+- Mike Protts added --ftp-ssl-control to make curl use FTP-SSL, but only
+  encrypt the control connection and use the data connection "plain".
+
+- Dmitriy Sergeyev provided a patch that made the SOCKS[45] code work better
+  as it now will read the full data sent from servers. The SOCKS-related code
+  was also moved to the new lib/socks.c source file.
+
+Daniel (21 September 2006)
+- Added test case 531 in an attempt to repeat bug report #1561470
+  (http://curl.haxx.se/bug/view.cgi?id=1561470) that is said to crash when an
+  FTP upload fails with the multi interface. It did not, but I made a failed
+  upload still assume the control connection to be fine.
+
+Daniel (20 September 2006)
+- Armel Asselin fixed problems when you gave a proxy URL with user name and
+  empty password or no password at all. Test case 278 and 279 were added to
+  verify.
+
+Daniel (12 September 2006)
+- Added docs/examples/10-at-a-time.c by Michael Wallner
+
+- Added docs/examples/hiperfifo.c by Jeff Pohlmeyer
+
+Daniel (11 September 2006)
+- Fixed my breakage from earlier today so that doing curl_easy_cleanup() on a
+  handle that is part of a multi handle first removes the handle from the
+  stack.
+
+- Added CURLOPT_SSL_SESSIONID_CACHE and --no-sessionid to disable SSL
+  session-ID re-use on demand since there obviously are broken servers out
+  there that misbehave with session-IDs used.
+
+- Jeff Pohlmeyer presented a *multi_socket()-using program that exposed a
+  problem with it (SIGSEGV-style). It clearly showed that the existing
+  socket-state and state-difference function wasn't good enough so I rewrote
+  it and could then re-run Jeff's program without any crash. The previous
+  version clearly could miss to tell the application when a handle changed
+  from using one socket to using another.
+
+  While I was at it (as I could use this as a means to track this problem
+  down), I've now added a 'magic' number to the easy handle struct that is
+  inited at curl_easy_init() time and cleared at curl_easy_cleanup() time that
+  we can use internally to detect that an easy handle seems to be fine, or at
+  least not closed or freed (freeing in debug builds fill the area with 0x13
+  bytes but in normal builds we can of course not assume any particular data
+  in the freed areas).
+
+Daniel (9 September 2006)
+- Michele Bini fixed how the hostname is put in NTLM packages. As servers
+  don't expect fully qualified names we need to cut them off at the first dot.
+
+- Peter Sylvester cleaned up and fixed the getsockname() uses in ftp.c. Some
+  of them can be completetly removed though...
+
+Daniel (6 September 2006)
+- Ravi Pratap and I have implemented HTTP Pipelining support. Enable it for a
+  multi handle using CURLMOPT_PIPELINING and all HTTP connections done on that
+  handle will be attempted to get pipelined instead of done in parallell as
+  they are performed otherwise.
+
+  As a side-effect from this work, connections are now shared between all easy
+  handles within a multi handle, so if you use N easy handles for transfers,
+  each of them can pick up and re-use a connection that was previously used by
+  any of the handles, be it the same or one of the others.
+
+  This separation of the tight relationship between connections and easy
+  handles is most noticable when you close easy handles that have been used in
+  a multi handle and check amount of used memory or watch the debug output, as
+  there are times when libcurl will keep the easy handle around for a while
+  longer to be able to close it properly. Like for sending QUIT to close down
+  an FTP connection.
+
+  This is a major change.
+  
+Daniel (4 September 2006)
+- Dmitry Rechkin (http://curl.haxx.se/bug/view.cgi?id=1551412) provided a
+  patch that while not fixing things very nicely, it does make the SOCKS5
+  proxy connection slightly better as it now acknowledges the timeout for
+  connection and it no longer segfaults in the case when SOCKS requires
+  authentication and you did not specify username:password.
+
+Daniel (31 August 2006)
+- Dmitriy Sergeyev found and fixed a multi interface flaw when using asynch
+  name resolves. It could get stuck in the wrong state.
+
+Gisle (29 August 2006)
+- Added support for other MS-DOS compilers (desides djgpp). All MS-DOS
+  compiler now uses the same config.dos file (renamed to config.h by
+  make). libcurl now builds fine using Watcom and Metaware's High-C
+  using the Watt-32 tcp/ip-stack.
+
+Daniel (29 August 2006)
+- David McCreedy added CURLOPT_SOCKOPTFUNCTION and CURLOPT_SOCKOPTDATA to
+  allow applications to set their own socket options.
+
+Daniel (25 August 2006)
+- Armel Asselin reported that the 'running_handles' counter wasn't updated
+  properly if you removed a "live" handle from a multi handle with
+  curl_multi_remove_handle().
+
+Daniel (22 August 2006)
+- David McCreedy fixed a remaining mistake from the August 19 TYPE change.
+
+- Peter Sylvester pointed out a flaw in the AllowServerConnect() in the FTP
+  code when doing pure ipv6 EPRT connections.
+
+Daniel (19 August 2006)
+- Based on a patch by Armel Asselin, the FTP code no longer re-issues the TYPE
+  command on subsequent requests on a re-used connection unless it has to.
+
+- Armel Asselin fixed a crash in the FTP code when using SINGLECWD mode and
+  files in the root directory.
+
+- Andrew Biggs pointed out a "Expect: 100-continue" flaw where libcurl didn't
+  send the whole request at once, even though the Expect: header was disabled
+  by the application. An effect of this change is also that small (< 1024
+  bytes) POSTs are now always sent without Expect: header since we deem it
+  more costly to bother about that than the risk that we send the data in
+  vain.
+
+Daniel (9 August 2006)
+- Armel Asselin made the CURLOPT_PREQUOTE option work fine even when
+  CURLOPT_NOBODY is set true. PREQUOTE is then run roughly at the same place
+  in the command sequence as it would have run if there would've been a
+  transfer.
+
+Daniel (8 August 2006)
+- Fixed a flaw in the "Expect: 100-continue" treatment. If you did two POSTs
+  on a persistent connection and allowed the first to use that header, you
+  could not disable it for the second request.
+
+Daniel (7 August 2006)
+- Domenico Andreolfound a quick build error which happened because
+  src/config.h.in was not a proper duplcate of lib/config.h.in which it
+  should've been and this was due to the maketgz script not doing the cp
+  properly.
+
+Version 7.15.5 (7 August 2006)
+
+Daniel (2 August 2006)
+- Mark Lentczner fixed how libcurl was not properly doing chunked encoding
+  if the header "Transfer-Encoding: chunked" was set by the application.
+  http://curl.haxx.se/bug/view.cgi?id=1531838
+
+Daniel (1 August 2006)
+- Maciej Karpiuk fixed a crash that would occur if we passed Curl_strerror()
+  an unknown error number on glibc systems.
+  http://curl.haxx.se/bug/view.cgi?id=1532289
+
+Daniel (31 July 2006)
+- *ALERT* curl_multi_socket() and curl_multi_socket_all() got modified
+  prototypes: they both now provide the number of running handles back to the
+  calling function. It makes the functions resemble the good old
+  curl_multi_perform() more and provides a nice way to know when the multi
+  handle goes empty.
+
+  ALERT2: don't use the curl_multi_socket*() functionality in anything
+  production-like until I say it's somewhat settled, as I suspect there might
+  be some further API changes before I'm done...
+
+Daniel (28 July 2006)
+- Yves Lejeune fixed so that replacing Content-Type: when doing multipart
+  formposts work exactly the way you want it (and the way you'd assume it
+  works).
+
+Daniel (27 July 2006)
+- David McCreedy added --ftp-ssl-reqd which makes curl *require* SSL for both
+  control and data connection, as the existing --ftp-ssl option only requests
+  it.
+
+- [Hiper-related work] Added a function called curl_multi_assign() that will
+  set a private pointer added to the internal libcurl hash table for the
+  particular socket passed in to this function:
+
+  CURLMcode curl_multi_assign(CURLM *multi_handle,
+                              curl_socket_t sockfd,
+                              void *sockp);
+
+  'sockp' being a custom pointer set by the application to be associated with
+  this socket. The socket has to be already existing and in-use by libcurl,
+  like having already called the callback telling about its existance.
+
+  The set hashp pointer will then be passed on to the callback in upcoming
+  calls when this same socket is used (in the brand new 'socketp' argument).
+
+Daniel (26 July 2006)
+- Dan Nelson added the CURLOPT_FTP_ALTERNATIVE_TO_USER libcurl option and curl
+  tool option named --ftp-alternative-to-user. It provides a mean to send a
+  particular command if the normal USER/PASS approach fails.
+
+- Michael Jerris added magic that builds lib/curllib.vcproj automatically for
+  newer MSVC.
+
+Daniel (25 July 2006)
+- Georg Horn made the transfer timeout error message include more details.
+
+Daniel (20 July 2006)
+- David McCreedy fixed a build error when building libcurl with HTTP disabled,
+  problem added with the curl_formget() patch.
+
+Daniel (17 July 2006)
+- Jari Sundell did some excellent research and bug tracking, figured out that
+  we did wrong and patched it: When nodes were removed from the splay tree,
+  and we didn't properly remove it from the splay tree when an easy handle was
+  removed from a multi stack and thus we could wrongly leave a node in the
+  splay tree pointing to (bad) memory.
+
+Daniel (14 July 2006)
+- David McCreedy fixed a flaw where the CRLF counter wasn't properly cleared
+  for FTP ASCII transfers.
+
+Daniel (8 July 2006)
+- Ates Goral pointed out that libcurl's cookie parser did case insensitive
+  string comparisons on the path which is incorrect and provided a patch that
+  fixes this. I edited test case 8 to include details that test for this.
+
+- Ingmar Runge provided a source snippet that caused a crash. The reason for
+  the crash was that libcurl internally was a bit confused about who owned the
+  DNS cache at all times so if you created an easy handle that uses a shared
+  DNS cache and added that to a multi handle it would crash. Now we keep more
+  careful internal track of exactly what kind of DNS cache each easy handle
+  uses: None, Private (allocated for and used only by this single handle),
+  Shared (points to a cache held by a shared object), Global (points to the
+  global cache) or Multi (points to the cache within the multi handle that is
+  automatically shared between all easy handles that are added with private
+  caches).
+
+Daniel (4 July 2006)
+- Toshiyuki Maezawa fixed a problem where you couldn't override the
+  Proxy-Connection: header when using a proxy and not doing CONNECT.
+
+Daniel (24 June 2006)
+- Michael Wallner added curl_formget(), which allows an application to extract
+  (serialise) a previously built formpost (as with curl_formadd()).
+
+Daniel (23 June 2006)
+- Arve Knudsen found a flaw in curl_multi_fdset() for systems where
+  curl_socket_t is unsigned (like Windows) that could cause it to wrongly
+  return a max fd of -1.
+
+Daniel (20 June 2006)
+- Peter Silva introduced CURLOPT_MAX_SEND_SPEED_LARGE and
+  CURLOPT_MAX_RECV_SPEED_LARGE that limit tha maximum rate libcurl is allowed
+  to send or receive data. This kind of adds the the command line tool's
+  option --limit-rate to the library.
+
+  The rate limiting logic in the curl app is now removed and is instead
+  provided by libcurl itself. Transfer rate limiting will now also work for -d
+  and -F, which it didn't before.
+
+Daniel (19 June 2006)
+- Made -K on a file that couldn't be read cause a warning to be displayed.
+
+Daniel (13 June 2006)
+- Dan Fandrich implemented --enable-hidden-symbols configure option to enable
+  -fvisibility=hidden on gcc >= 4.0.  This reduces the size of the libcurl
+  binary and speeds up dynamic linking by hiding all the internal symbols from
+  the symbol table.

   Changelog for the c-ares project
 
+* November 22
+
+- Install ares_dns.h too
+
+- Michael Wallner fixed this problem: When I set domains in the options
+  struct, and there are domain/search entries in /etc/resolv.conf, the domains
+  of the options struct will be overridden.
+
+* November 6
+
+- Yang Tse removed a couple of potential zero size memory allocations.
+
+- Andreas Rieke fixed the line endings in the areslib.dsp file that I (Daniel)
+  broke in the 1.3.2 release. We should switch to a system where that file is
+  auto-generated. We could rip some code for that from curl...
+
+Version 1.3.2 (November 3, 2006)
+
+* October 12 2006
+
+- Prevent ares_getsock() to overflow if more than 16 sockets are used.
+
+* September 11 2006
+
+- Guilherme Balena Versiani: I noted a strange BUG in Win32 port
+  (ares_init.c/get_iphlpapi_dns_info() function): when I disable the network
+  by hand or disconnect the network cable in Windows 2000 or Windows XP, my
+  application gets 127.0.0.1 as the only name server. The problem comes from
+  'GetNetworkParams' function, that returns the empty string "" as the only
+  name server in that case. Moreover, the Windows implementation of
+  inet_addr() returns INADDR_LOOPBACK instead of INADDR_NONE.
+
+* August 29 2006
+
+- Brad Spencer did
+
+  o made ares_version.h use extern "C" for c++ compilers
+  o fixed compiler warnings in ares_getnameinfo.c
+  o fixed a buffer position init for TCP reads
+
+* August 3 2006
+
+- Ravi Pratap fixed ares_getsock() to actually return the proper bitmap and
+  not always zero!
+
+Version 1.3.1 (June 24, 2006)
+
+* July 23, 2006
+
+- Gisle Vanem added getopt() to the ahost program. Currently accepts
+  only [-t {a|aaaa}] to specify address family in ares_gethostbyname().
+
+* June 19, 2006
+
+- (wahern) Removed "big endian" DNS section and RR data integer parser
+  macros from ares_dns.h, which break c-ares on my Sparc64. Bit-wise
+  operations in C operate on logical values. And in any event the octets are
+  already in big-endian (aka network) byte order so they're being reversed
+  (thus the source of the breakage).
+
+* June 18, 2006
+
+- William Ahern handles EAGAIN/EWOULDBLOCK errors in most of the I/O calls
+  from area_process.c.
+
+  TODO: Handle one last EAGAIN for a UDP socket send(2) in
+  ares__send_query().

+eCos
+====
+   curl does not use the eCos build system, so you must first build eCos
+   separately, then link curl to the resulting eCos library.  Here's a sample
+   configure line to do so on an x86 Linux box targeting x86:
+
+   GCCLIB=`gcc -print-libgcc-file-name` && \
+   CFLAGS="-D__ECOS=1 -nostdinc -I$ECOS_INSTALL/include \
+    -I`dirname $GCCLIB`/include" \
+   LDFLAGS="-nostdlib -Wl,--gc-sections -Wl,-static \
+    -L$ECOS_INSTALL/lib -Ttarget.ld -ltarget" \
+   ./configure --host=i386 --disable-shared \
+    --without-ssl --without-zlib --disable-manual --disable-ldap
+
+   In most cases, eCos users will be using libcurl from within a custom
+   embedded application.  Using the standard 'curl' executable from
+   within eCos means facing the limitation of the standard eCos C
+   startup code which does not allow passing arguments in main().  To
+   run 'curl' from eCos and have it do something useful, you will need
+   to either modify the eCos startup code to pass in some arguments, or
+   modify the curl application itself to retrieve its arguments from
+   some location set by the bootloader or hard-code them.
+
+   Something like the following patch could be used to hard-code some
+   arguments.  The MTAB_ENTRY line mounts a RAM disk as the root filesystem
+   (without mounting some kind of filesystem, eCos errors out all file
+   operations which curl does not take to well).  The next section synthesizes
+   some command-line arguments for curl to use, in this case to direct curl
+   to read further arguments from a file.  It then creates that file on the
+   RAM disk and places within it a URL to download: a file: URL that
+   just happens to point to the configuration file itself.  The results
+   of running curl in this way is the contents of the configuration file
+   printed to the console.

+
+Requires glib-2.x and a (POSIX?) system that has mkfifo().
+
+This is an adaptation of libcurl's "hipev.c" and libevent's "event-test.c"
+sample programs, adapted to use glib's g_io_channel in place of libevent.
+
+When running, the program creates the named pipe "hiper.fifo"
+
+Whenever there is input into the fifo, the program reads the input as a list
+of URL's and creates some new easy handles to fetch each URL via the
+curl_multi "hiper" API.
+
+
+Thus, you can try a single URL:
+  % echo http://www.yahoo.com > hiper.fifo
+
+Or a whole bunch of them:
+  % cat my-url-list > hiper.fifo
+
+The fifo buffer is handled almost instantly, so you can even add more URL's
+while the previous requests are still being downloaded.
+
+This is purely a demo app, all retrieved data is simply discarded by the write
+callback.

+ * Example application source code using the multi socket interface to
+ * download many files at once.
+ *
+ * Written by Jeff Pohlmeyer
+
+Requires libevent and a (POSIX?) system that has mkfifo().
+
+This is an adaptation of libcurl's "hipev.c" and libevent's "event-test.c"
+sample programs.
+
+When running, the program creates the named pipe "hiper.fifo"
+
+Whenever there is input into the fifo, the program reads the input as a list
+of URL's and creates some new easy handles to fetch each URL via the
+curl_multi "hiper" API.
+
+
+Thus, you can try a single URL:
+  % echo http://www.yahoo.com > hiper.fifo
+
+Or a whole bunch of them:
+  % cat my-url-list > hiper.fifo
+
+The fifo buffer is handled almost instantly, so you can even add more URL's
+while the previous requests are still being downloaded.
+
+Note:
+  For the sake of simplicity, URL length is limited to 1023 char's !
+
+This is purely a demo app, all retrieved data is simply discarded by the write
+callback.

+This function assigns an association in the multi handle between the given

+When set, the \fIsockptr\fP pointer will be passed to all future socket

 .SH DESCRIPTION
-Alternative versions of \fIcurl_multi_perform()\fP that allows the application
-to pass in one of the file descriptors/sockets that have been detected to have
-\&"action" on them and let libcurl perform. This allows libcurl to not have to
-scan through all possible file descriptors to check for action. When the
-application has detected action on a socket handled by libcurl, it should call
-\fIcurl_multi_perform()\fP with the \fBsockfd\fP argument set to the socket
-with the action.

+still running easy handles within the multi handle. When this number reaches
+zero, all transfers are complete/done. Note that when you call
+\fIcurl_multi_socket(3)\fP on a specific socket and the counter decreases by
+one, it DOES NOT necessarily mean that this exact socket/transfer is the one
+that completed. Use \fIcurl_multi_info_read(3)\fP to figure out which easy
+handle that completed.
+
+The curl_multi_socket functions inform the application about updates in the
+socket (file descriptor) status by doing none, one or multiple calls to the
+socket callback function set with the CURLMOPT_SOCKETFUNCTION option to
 \fIcurl_multi_setopt(3)\fP. They update the status with changes since the
 previous time this function was called.

-\fBcurl_multi_socket_all(3)\fP instead.

+.SH "CALLBACK DETAILS"
 
 The socket \fBcallback\fP function uses a prototype like this
 .nf
 
-     int curl_socket_callback(CURL *easy,      /* easy handle */
-                              curl_socket_t s, /* socket */

+  int curl_socket_callback(CURL *easy,      /* easy handle */
+                           curl_socket_t s, /* socket */
+                           int action,      /* see values below */
+                           void *userp,    /* private callback pointer */
+                           void *socketp); /* private socket pointer */
 
 .fi
 The callback MUST return 0.
 
-The \fIaction\fP (third) argument to the callback has one of five values:
+The \fIeasy\fP argument is a pointer to the easy handle that deals with this
+particular socket. Note that a single handle may work with several sockets
+simultaneously.
+
+The \fIs\fP argument is the actual socket value as you use it within your
+system.

+The \fIsocketp\fP argument is a private pointer you have previously set with
