+Version 7.14.0 (16 May 2005)
+
+Daniel (13 May 2005)
+- Grigory Entin reported that curl's configure detects a fine poll() for Mac
+  OS X 10.4 (while 10.3 or later detected a "bad" one), but the executable
+  doesn't work as good as if built without poll(). I've adjusted the configure
+  to always skip the fine-poll() test on Mac OS X (darwin).
+
+Daniel (12 May 2005)
+- When doing a second request (after a disconnect) using the same easy handle,
+  over a proxy that uses NTLM authentication, libcurl failed to use NTLM again
+  properly (the auth method was accidentally reset to the same as had been set
+  for host auth, which defaults to Basic). Bug report #1200661 identified the
+  the problem and the fix.
+
+- If -z/--time-cond is used with an invalid date syntax, this is no longer
+  silently discarded. Instead a proper warning message is diplayed that
+  informs about it. But it still continues without the condition.
+
+Version 7.14.0-pre2 (11 May 2005)
+
+Daniel (11 May 2005)
+- Starting now, libcurl sends a little different set of headers in its default
+  HTTP requests:
+  
+  A) Normal non-proxy HTTP:
+    - no more "Pragma: no-cache" (this only makes sense to proxies)
+
+  B) Non-CONNECT HTTP request over proxy:
+    - "Pragma: no-cache" is used (like before)
+    - "Proxy-Connection: Keep-alive" (for older style 1.0-proxies)
+
+  C) CONNECT HTTP request over proxy:
+    - "Host: [name]:[port]"
+    - "Proxy-Connection: Keep-alive"
+
+  The A) case is mostly to reduce the default header size and remove a
+  pointless header.
+
+  The B) is to address (rare) problems with HTTP 1.0 proxies
+
+  The C) headers are both to address (rare) problems with some proxies. The
+  code in libcurl that deals with CONNECT requests need a rewrite, but it
+  feels like a too big a job for me to do now. Details are added in the code
+  comments for now.
+
+  Updated a large amount of test cases to reflect the news.
+
+Daniel (10 May 2005)
+- Half-baked attempt to bail out if select() returns _only_ errorfds when the
+  transfer is in progress. An attempt to fix Allan's problem. See
+  http://curl.haxx.se/mail/lib-2005-05/0073.html and the rest of that thread
+  for details.
+
+  I'm still not sure this is the right fix, but...
+
+Version 7.14.0-pre1 (9 May 2005)
+
+Daniel (2 May 2005)
+- Sort of "fixed" KNOWN_BUGS #4: curl now builds IPv6 enabled on AIX 4.3. At
+  least it should no longer cause a compiler error. However, it does not have
+  AI_NUMERICHOST so we cannot getaddrinfo() any numerical addresses with it
+  (we use that for FTP PORT/EPRT)! So, I modified the configure check that
+  checks if the getaddrinfo() is working, to use AI_NUMERICHOST since then
+  it'll fail on AIX 4.3 and it will automatically build with IPv6 support
+  disabled.
+
+- Added --trace-time that when used adds a time stamp to each trace line that
+  --trace, --trace-ascii and --verbose output. I also made the '>' display
+  separate each line on the linefeed so that HTTP requests etc look nicer in
+  the -v output.
+
+- Made curl recognize the environment variables Lynx (and others?) support for
+  pointing out the CA cert path/file: SSL_CERT_DIR and SSL_CERT_FILE. If
+  CURL_CA_BUNDLE is not set, they are checked afterwards.
+
+  Like before: on windows if none of these are set, it checks for the ca cert
+  file like this:
+
+  1. application's directory
+  2. current working directory
+  3. Windows System directory (e.g. C:\windows\system32)
+  4. Windows Directory (e.g. C:\windows)
+  5. all directories along %PATH%
+
+Daniel (1 May 2005)
+- The runtests.pl script now starts test servers by doing fork() and exec()
+  instead of the previous approach. This is less complicated and should
+  hopefully lead to less "leaked" servers (servers that aren't stopped
+  properly when the tests are stopped).
+
+- Alexander Zhuravlev found a case when you did "curl -I [URL]" and it
+  complained on the chunked encoding, even though a HEAD should never return a
+  body and thus it cannot be a chunked-encoding problem!
+
+Daniel (30 April 2005)
+- Alexander Zhuravlev found out that (lib)curl SIGSEGVed when using
+  --interface on an address that can't be bound.
+
+Daniel (28 April 2005)
+- Working on fixing up test cases to mark sections as 'mode=text' for things
+  that curl writes as text files, since then they can get different line
+  endings depending on OS. Andr<64>s Garc<72>a helps me work this out.
+
+  Did lots of other minor tweaks on the test scripts to work better and more
+  reliably find test servers and also kill test servers.
+
+- Dan Fandrich pointed out how the runtests.pl script killed the HTTP server
+  instead of the HTTPS server when closing it down.
+
+Daniel (27 April 2005)
+- Paul Moore made curl check for the .curlrc file (_curlrc on windows) on two
+  more places. First, CURL_HOME is a new environment variable that is used
+  instead of HOME if it is set, to point out where the default config file
+  lives. If there's no config file in the dir pointed out by one of the
+  environment variables, the Windows version will instead check the same
+  directory the executable curl is located in.
+
+Daniel (26 April 2005)
+- Cory Nelson's work on nuking compiler warnings when building on x64 with
+  VS2005.
+
+Daniel (25 April 2005)
+- Fred New reported a bug where we used Basic auth and user name and password
+  in .netrc, and when following a Location: the subsequent requests didn't
+  properly use the auth as found in the netrc file. Added test case 257 to
+  verify my fix.
+
+- Based on feedback from Cory Nelson, I added some preprocessor magic in
+  */setup.h and */config-win32.h to build fine with VS2005 on x64.
+
+Daniel (23 April 2005)
+- Alex Suykov made the curl tool now assume that uploads using HTTP:// or
+  HTTPS:// are the only ones that show output and thus motivates a switched
+  off progress meter if the output is sent to the terminal. This makes FTP
+  uploads without '>', -o or -O show the progress meter.
+
+Daniel (22 April 2005)
+- Dave Dribin's MSVC makefile fix: set CURL_STATICLIB when it builds static
+  library variants.
+
+- Andres Garcia fixed configure to set the proper define when building static
+  libcurl on windows.
+
+- --retry-delay didn't work.
+
+Daniel (18 April 2005)
+- Olivier reported that even though he used CURLOPT_PORT, libcurl clearly
+  still used the default port. He was right. I fixed the problem and added the
+  test cases 521, 522 and 523 to verify the fix.
+
+- Toshiyuki Maezawa reported that when doing a POST with a read callback,
+  libcurl didn't properly send an Expect: 100-continue header. It does now.
+
+- I committed by mig change in the test suite's FTP server that moves out all
+  socket/TCP code to a separate C program named sockfilt. And added 4 new
+  test cases for FTP over IPv6.
+
+Daniel (8 April 2005)
+- Cory Nelson reported a problem with a HTTP server that responded with a 304
+  response containing an "illegal" Content-Length: header, which was not
+  properly ignored by libcurl. Now it is. Test case 249 verifies.
+
+Daniel (7 April 2005)
+- Added ability to build and run with GnuTLS as an alternative to OpenSSL for
+  the secure layer. configure --with-gnutls enables with. Note that the
+  previous OpenSSL check still has preference and if it first detects OpenSSL,
+  it will not check for GnuTLS. You may need to explictly diable OpenSSL with
+  --without-ssl.
+
+  This work has been sponsored by The Written Word.
+
+Daniel (5 April 2005)
+- Christophe Legry fixed the post-upload check for FTP to not complain if the
+  upload was skipped due to a time-condition as set with
+  CURLOPT_TIMECONDITION. I added test case 247 and 248 to verify.
+

   Changelog for the c-ares project
 
+* May 14
+
+- Added an inet_ntop function from BIND for systems that do not have it.
+
+* April 9
+
+- Made sortlist support IPv6 (this can probably use some testing).
+
+- Made sortlist support CIDR matching for IPv4.
+
+* April 8
+
+- Added preliminary IPv6 support to ares_gethostbyname. Currently, sortlist
+  does not work with IPv6. Also provided an implementation of bitncmp from
+  BIND for systems that do not supply this function. This will be used to add
+  IPv6 support to sortlist.
+
+- Made ares_gethostbyaddr support IPv6 by specifying AF_INET6 as the family.
+  The function can lookup IPv6 addresses both from files (/etc/hosts) and
+  DNS lookups.

+  pure numbers, such as 127.0.0.1 or ::1.
+
+  5.10 How do I prevent libcurl from writing the response to stdout?
+
+  libcurl provides a default built-in write function that writes received data
+  to stdout. Set a WRITEFUNCTION to receive the data, or possibly set
+  WRITEDATA to a different FILE * handle.
+
+  5.11 How do I make libcurl not receive the whole HTTP response?
+
+  You make the write callback (or progress callback) return an error and
+  libcurl will then abort the transfer.
+
+  5.12 Can I make libcurl fake or hide my real IP address?
+
+  No. libcurl operates on a higher level than so. Besides, faking IP address
+  would imply sending IP packages with a made-up source address, and then you
+  normally get a problem with intercepting the packages sent back as they
+  would then not be routed to you!
+
+  If you use a proxy to access remote sites, the sites will not see your local
+  IP address but instead the address of the proxy.
+
+  Also note that on many networks NATs or other IP-munging techniques are used
+  that makes you see and use a different IP address locally than what the
+  remote server will see you coming from.

+This option determines whether curl verifies the authenticity of the

+
+When negotiating an SSL connection, the server sends a certificate
+indicating its identity.  Curl verifies whether the certificate is
+authentic, i.e. that you can trust that the server is who the
+certificate says it is.  This trust is based on a chain of digital
+signatures, rooted in certification authority (CA) certificates you
+supply.  As of 7.10, curl installs a default bundle of CA certificates
+and you can specify alternate certificates with the
+\fICURLOPT_CAINFO\fP option or the \fICURLOPT_CAPATH\fP option.
+
+When \fICURLOPT_SSL_VERIFYPEER\fP is nonzero, and the verification
+fails to prove that the certificate is authentic, the connection
+fails.  When the option is zero, the connection succeeds regardless.
+
+Authenticating the certificate is not by itself very useful.  You

+ *          curl_multi_socket_all() instead.
+ *
+ *          curl_multi_perform() is thus the equivalent of calling
+ *          curl_multi_socket_all(handle, NULL, NULL);
+ *
+ *          IMPLEMENTATION: libcurl will need an internal hash table to map
+ *          socket numbers to internal easy handles for the cases when 'easy'
+ *          is set to CURL_EASY_NONE.
+ *
+ *          Regarding the timeout argument in the callback: it is the timeout
+ *          (in milliseconds) for waiting on action on this socket (and the
+ *          given time period starts when the callback is called) until you
+ *          should call curl_multi_socket() with the timeout stuff mentioned
+ *          above. If "actions" happens on the socket before the timeout
+ *          happens, remember that the timout timer keeps ticking until told
+ *          otherwise.
+ *
+ *          The "what" argument has one of five values:
+ *
+ *            0 CURL_POLL_NONE (0)   - register, not interested in readiness
+ *            1 CURL_POLL_IN         - register, interested in read readiness
+ *            2 CURL_POLL_OUT        - register, interested in write readiness
+ *            3 CURL_POLL_INOUT      - register, interested in both
+ *            4 CURL_POLL_REMOVE     - deregister

+Things to fix for the GnuTLS support
+====================================
+
+* make the configure --with-ssl option first check for OpenSSL and then for
+  GnuTLS if OpenSSL wasn't detected.
+
+* Get NTLM working using the functions provided by libgcrypt, since GnuTLS
+  already depends on that to function. Not strictly SSL/TLS related, but
+  hey... Another option is to get available DES and MD4 source code from the

+  SRP for TLS

+* Work out a common method with Peter Sylvester's OpenSSL-patch for SRP
