Daniel (7 March 2006)
- Markus Koetter filed debian bug report #355715 which identified a problem
  with the multi interface and multi-part formposts. The fix from February
  22nd could make the Curl_done() function get called twice on the same
  connection and it was not designed for that and thus tried to call free() on
  an already freed memory area!

- Peter Heuchert made sure the CURLFTPSSL_CONTROL setting for CURLOPT_FTP_SSL
  is used properly.

Daniel (6 March 2006)
- Lots of users on Windows have reported getting the "SSL: couldn't set
  callback" error message so I've now made the setting of that callback not be
  as critical as before. The function is only used for additional loggging/
  trace anyway so a failure just means slightly less data. It should still be
  able to proceed and connect fine to the server.

Daniel (4 March 2006)
- Thomas Klausner provided a patch written by Todd Vierling in bug report
  #1442471 that fixes a build problem on Interix.

Daniel (2 March 2006)
- FTP upload without a file name part in the URL now causes
  curl_easy_perform() to return CURLE_URL_MALFORMAT. Previously it allowed the
  upload but named the file "(nil)" (without the quotes). Test case 524
  verifies.

- Added a check for getprotobyname in configure so that it'll be used, thanks
  to Gisle Vanem's change the other day.

Daniel (28 February 2006)
- Dan Fandrich prevented curl from getting stuck in an endless loop in case we
  are out of file handles very early in curl's code where it makes sure that
  0, 1 and 2 aren't gonna be used by the lib for transfers.

Daniel (27 February 2006)
- Marty Kuhrt pointed out that there were two VMS-specific files missing in
  the release archive.

Version 7.15.2 (27 February 2006)

Daniel (22 February 2006)
- Lots of work and analysis by "xbx___" in bug #1431750
  (http://curl.haxx.se/bug/view.cgi?id=1431750) helped me identify and fix two
  different but related bugs:

  1) Removing an easy handle from a multi handle before the transfer is done
     could leave a connection in the connection cache for that handle that is
     in a state that isn't suitable for re-use. A subsequent re-use could then
     read from a NULL pointer and segfault.

  2) When an easy handle was removed from the multi handle, there could be an
     outstanding c-ares DNS name resolve request. When the response arrived,
     it caused havoc since the connection struct it "belonged" to could've
     been freed already.

  Now Curl_done() is called when an easy handle is removed from a multi handle
  pre-maturely (that is, before the transfer was complteted). Curl_done() also
  makes sure to cancel all (if any) outstanding c-ares requests.

Daniel (21 February 2006)
- Peter Su added support for SOCKS4 proxies. Enable this by setting the proxy
  type to the already provided type CURLPROXY_SOCKS4.

  I added a --socks4 option that works like the current --socks5 option but
  instead use the socks4 protocol.

Daniel (20 February 2006)
- Shmulik Regev fixed an issue with multi-pass authentication and compressed
  content when libcurl didn't honor the internal ignorebody flag.

Daniel (18 February 2006)
- Ulf Härnhammar fixed a format string (printf style) problem in the Negotiate
  code. It should however not be the cause of any troubles. He also fixed a
  few similar problems in the HTTP test server code.

Daniel (17 February 2006)
- Shmulik Regev provided a fix for the DNS cache when using short life times,
  as previously it could be holding on to old cached entries longer than
  requested.

Daniel (11 February 2006)
- Karl Moerder added the CURLOPT_CONNECT_ONLY and CURLINFO_LASTSOCKET options
  that an app can use to let libcurl only connect to a remote host and then
  extract the socket from libcurl. libcurl will then not attempt to do any
  transfer at all after the connect is done.

- Kent Boortz improved the configure check for GnuTLS to properly set LIBS
  instead of LDFLAGS.

Daniel (8 February 2006)
- Philippe Vaucher provided a brilliant piece of test code that show a problem
  with re-used FTP connections. If the second request on the same connection
  was set not to fetch a "body", libcurl could get confused and consider it an
  attempt to use a dead connection and would go acting mighty strange.

Daniel (2 February 2006)
- Make --limit-rate [num] mean bytes. It used to be that but it broke in my
  change done in November 2005.

Daniel (30 January 2006)
- Added CURLOPT_LOCALPORT and CURLOPT_LOCALPORTRANGE to libcurl. Set with the
  curl tool with --local-port. Plain and simply set the range of ports to bind
  the local end of connections to. Implemented on to popular demand.

- Based on an error report by Philippe Vaucher, we no longer count a retried
  connection setup as a follow-redirect. It turns out 1) this fails when a FTP
  connection is re-setup and 2) it does make the max-redirs counter behave
  wrong.

Daniel (24 January 2006)
- Michal Marek provided a patch for FTP that makes libcurl continue to try
  PASV even after EPSV returned a positive response code, if libcurl failed to
  connect to the port number the EPSV response said. Obviously some people are
  going through protocol-sensitive firewalls (or similar) that don't
  understand EPSV and then they don't allow the second connection unless PASV
  was used. This also called for a minor fix of test case 238.

Daniel (20 January 2006)
- Duane Cathey was one of our friends who reported that curl -P [IP]
  (CURLOPT_FTPPORT) didn't work for ipv6-enabed curls if the IP wasn't a
  "native" IP while it works fine for ipv6-disabled builds!

  In the process of fixing this, I removed the support for LPRT since I can't
  think of many reasons to keep doing it and asking on the mailing list didn't
  reveal anyone else that could either. The code that sends EPRT and PORT is
  now also a lot simpler than before (IMHO).

Daniel (19 January 2006)
- Jon Turner pointed out that doing -P [hostname] (CURLOPT_FTPPORT) with curl
  (built ipv4-only) didn't work.

Daniel (18 January 2006)
- As reported in bug #1408742 (http://curl.haxx.se/bug/view.cgi?id=1408742),
  the configure script complained about a missing "missing" script if you ran
  configure within a path whose name included one or more spaces. This is due
  to a flaw in automake (1.9.6 and earlier). I've now worked around it by
  including an "overloaded" version of the AM_MISSING_HAS_RUN script that'll
  be used instead of the one automake ships with. This kludge needs to be
  removed once we get an automake version with this problem corrected.
  Possibly we'll then need to convert this into a kludge depending on what
  automake version that is used and that is gonna be painful and I don't even
  want to think about that now...!

Daniel (17 January 2006)
- David Shaw: Here is the latest libcurl.m4 autoconf tests. It is updated with
  the latest features and protocols that libcurl supports and has a minor fix
  to better deal with the obscure case where someone has more than one libcurl
  installed at the same time.

Daniel (16 January 2006)
- David Shaw finally removed all traces of Gopher and we are now officially
  not supporting it. It hasn't been functioning for years anyway, so this is
  just finally stating what already was true. And a cleanup at the same time.

- Bryan Henderson turned the 'initialized' variable for curl_global_init()
  into a counter, and thus you can now do multiple curl_global_init() and you
  are then supposed to do the same amount of calls to curl_global_cleanup().
  Bryan has also updated the docs accordingly.

Daniel (13 January 2006)
- Andrew Benham fixed a race condition in the test suite that could cause the
  test script to kill all processes in the current process group!

Daniel (12 January 2006)
- Michael Jahn:

  Fixed FTP_SKIP_PASV_IP and FTP_USE_EPSV to "do right" when used on FTP thru
  HTTP proxy.

  Fixed PROXYTUNNEL to work fine when you do ftp through a proxy.  It would
  previously overwrite internal memory and cause unpredicted behaviour!

Daniel (11 January 2006)
- I decided to document the "secret option" here now, as I've received *NO*
  feedback at all on my mailing list requests from November 2005:

  I'm looking for feedback and comments. I added some experimental code the
  other day, that allows a libcurl user to select what method libcurl should
  use to reach a file on a FTP(S) server.

  This functionality is available in CVS code and in recent daily snapshots.

  Let me explain...

  The current name for the option is CURLOPT_FTP_FILEMETHOD (--ftp-method for
  the command line tool) and you set it to a long (there are currenly no
  defines for the argument values, just plain numericals). You can set three
  different "methods" that do this:

  1 multicwd - like today, curl will do a single CWD operation for each path
           part in the given URL. For deep hierarchies this means very many
