+    (source).
+
+  mkdir (path)
+    Creates a new directory at (path).
+
+  rename (source) (dest)
+    Moves the file or directory at (source) to (dest).
+
+  rm (path)
+    Deletes the file located at (path).
+
+  rmdir (path)
+    Deletes the directory located at (path). This command will raise an error
+    if the directory is not empty.
+
+  symlink (source) (dest)
+    Same as ln.
+
+Daniel S (1 April 2007)
+- Robert Iakobashvili made curl_multi_remove_handle() a lot faster when many
+  easy handles are added to a multi handle, by avoiding the looping over all
+  the handles to find which one to remove.
+
+- Matt Kraai provided a patch that makes curl build on QNX 6 fine again.
+
+Daniel S (31 March 2007)
+- Fixed several minor issues detected by the coverity.com scanner.
+
+- "Pixel" fixed a problem that appeared when you used -f with user+password
+  embedded in the URL.
+
+Dan F (29 March 2007)
+- Don't tear down the ftp connection if the maximum filesize was exceeded
+  and added tests 290 and 291 to check.
+
+- Added ftps upload and SSL required tests 401 and 402.
+
+- Send an EOF message before closing an SCP channel, as recommended by
+  RFC4254. Enable libssh2 tracing when ssh debugging is turned on.
+
+Yang Tse (27 March 2007)
+- Internal function Curl_select() renamed to Curl_socket_ready()
+
+  New Internal wrapper function Curl_select() around select (2), it
+  uses poll() when a fine poll() is available, so now libcurl can be
+  built without select() support at all if a fine poll() is available.
+
+Daniel S (25 March 2007)
+- Daniel Johnson fixed multi code to traverse the easy handle list properly.
+  A left-over bug from the February 21 fix.
+
+Dan F (23 March 2007)
+- Added --pubkey option to curl and made --key also work for SCP/SFTP,
+  plus made --pass work on an SSH private key as well.
+
+- Changed the test harness to attempt to gracefully shut down servers
+  before resorting to the kill -9 hammer.
+
+- Added test harness infrastructure to support scp/sftp tests, using
+  OpenSSH as the server.
+
+- Fixed a memory leak when specifying a proxy with a file: URL.
+
+Yang Tse (20 March 2007)
+- Fixed: When a signal was caught awaiting for an event using Curl_select()
+  or Curl_poll() with a non-zero timeout both functions would restart the
+  specified timeout. This could even lead to the extreme case that if a
+  signal arrived with a frecuency lower to the specified timeout neither
+  function would ever exit.
+
+  Added experimental symbol definition check CURL_ACKNOWLEDGE_EINTR in
+  Curl_select() and Curl_poll(). When compiled with CURL_ACKNOWLEDGE_EINTR
+  defined both functions will return as soon as a signal is caught. Use it
+  at your own risk, all calls to these functions in the library should be
+  revisited and checked before fully supporting this feature.
+
+Yang Tse (19 March 2007)
+- Bryan Henderson fixed the progress function so that it can get called more
+  frequently allowing same calling frecuency for the client progress callback.
+  
+Dan F (15 March 2007)
+- Various memory leaks plugged and NULL pointer fixes made in the ssh code.
+
+Daniel (15 March 2007)
+- Nick made the curl tool accept globbing ranges that only is one number, i.e
+  you can now use [1-1] without curl complaining.
+
+Daniel (10 March 2007)
+- Eygene Ryabinkin:
+
+  The problem is the following: when we're calling Curl_done and it decides to
+  keep the connection opened ('left intact'), then the caller is not notified
+  that the connection was done via the NULLifying of the pointer, so some easy
+  handle is keeping the pointer to this connection.
+
+  Later ConnectionExists can select such connection for reuse even if we're
+  not pipelining: pipeLen is zero, so the (pipeLen > 0 && !canPipeline) is
+  false and we can reuse this connection for another easy handle. But thus the
+  connection will be shared between two easy handles if the handle that wants
+  to take the ownership is not the same as was not notified of the connection
+  was done in Curl_done. And when some of these easy handles will get their
+  connection really freed the another one will still keep the pointer.
+
+  My fix was rather trivial: I just added the NULLification to the 'else'
+  branch in the Curl_done. My tests with Git and ElectricFence showed no
+  problems both for HTTP pulling and cloning. Repository size is about 250 Mb,
+  so it was a considerable amount of Curl's work.
+
+Dan F (9 March 2007)
+- Updated the test harness to add a new "crypto" feature check and updated the
+  appropriate test case to use it.  For now, this is treated the same as the
+  "SSL" feature because curl doesn't list it separately.
+
+Daniel (9 March 2007)
+- Robert Iakobashvili fixed CURLOPT_INTERFACE for IPv6.
+
+- Robert A. Monat improved the maketgz and VC6/8 generating to set the correct
+  machine type too.
+
+- Justin Fletcher fixed a file descriptor leak in the curl tool when trying to
+  upload a file it couldn't open. Bug #1676581
+  (http://curl.haxx.se/bug/view.cgi?id=1676581)
+
+Dan F (9 March 2007)
+- Updated the test harness to check for protocol support before running each
+  test, fixing KNOWN_BUGS #11.
+
+Dan F (7 March 2007)
+- Reintroduced (after a 3 year hiatus) an FTPS test case (400) into the test
+  harness.  It is very limited as it supports only ftps:// URLs with
+  --ftp-ssl-control specified, which implicitly encrypts the control
+  channel but not the data channels.  That allows stunnel to be used with
+  an unmodified ftp server in exactly the same way that the test https
+  server is set up.
+
+Dan F (7 March 2007)
+- Honour --ftp-ssl-control on ftps:// URLs to allow encrypted control and
+  unencrypted data connections.
+
+Dan F (6 March 2007)
+- Fixed a couple of improper pointer uses detected by valgrind in test
+  cases 181 & 216.
+
+Daniel (2 March 2007)
+- Robert A. Monat and Shmulik Regev helped out to fix the new */Makefile.vc8
+  makefiles that are included in the source release archives, generated from
+  the Makefile.vc6 files by the maketgz script. I also modified the root
+  Makefile to have a VC variable that defaults to vc6 but can be overridden to
+  allow it to be used for vc8 as well. Like this:
+
+    nmake VC=vc8 vc
+
+Daniel (27 February 2007)
+- Hang Kin Lau found and fixed: When I use libcurl to connect to an https
+  server through a proxy and have the remote https server port set using the
+  CURLOPT_PORT option, protocol gets reset to http from https after the first
+  request.
+ 
+  User defined URL was modified internally by libcurl and subsequent reuse of
+  the easy handle may lead to connection using a different protocol (if not
+  originally http).
+ 
+  I found that libcurl hardcoded the protocol to "http" when it tries to
+  regenerate the URL if CURLOPT_PORT is set. I tried to fix the problem as
+  follows and it's working fine so far
+
+Daniel (25 February 2007)
+- Adam D. Moss made the HTTP CONNECT procedure less blocking when used from
+  the multi interface. Note that it still does a part of the connection in a
+  blocking manner.
+
+Daniel (23 February 2007)
+- Added warning outputs if the command line uses more than one of the options
+  -v, --trace and --trace-ascii, since it could really confuse the user.
+  Clarified this fact in the man page.
+
+Daniel (21 February 2007)
+- Ravi Pratap provided work on libcurl making pipelining more robust and
+  fixing some bugs:
+  o Don't mix GET and POST requests in a pipeline
+  o Fix the order in which requests are dispatched from the pipeline
+  o Fixed several curl bugs with pipelining when the server is returning
+    chunked encoding:
+    * Added states to chunked parsing for final CRLF
+    * Rewind buffer after parsing chunk with data remaining
+    * Moved chunked header initializing to a spot just before receiving
+      headers
+
+Daniel (20 February 2007)
+- Linus Nielsen Feltzing changed the CURLOPT_FTP_SSL_CCC option to handle
+  active and passive CCC shutdown and added the --ftp-ssl-ccc-mode command
+  line option.
+
+Daniel (19 February 2007)
+- Ian Turner fixed the libcurl.m4 macro's support for --with-libcurl.
+
+- Shmulik Regev found a memory leak in re-used HTTPS connections, at least
+  when the multi interface was used.
+
+- Robson Braga Araujo made passive FTP transfers work with SOCKS (both 4 and
+  5).
+
+Daniel (18 February 2007)
+- Jeff Pohlmeyer identified two problems: first a rather obscure problem with
+  the multi interface and connection re-use that could make a
+  curl_multi_remove_handle() ruin a pointer in another handle.
+
+  The second problem was less of an actual problem but more of minor quirk:
+  the re-using of connections wasn't properly checking if the connection was
+  marked for closure.
+
+Daniel (16 February 2007)
+- Duncan Mac-Vicar Prett and Michal Marek reported problems with resetting
+  CURLOPT_RANGE back to no range on an easy handle when using FTP.
+
+Dan F (14 February 2007)
+- Fixed curl-config --libs so it doesn't list unnecessary libraries (and
+  therefore introduce unnecessary dependencies) when it's not needed.
+  Also, don't bother adding a library path of /usr/lib
+
+Daniel (13 February 2007)
+- The default password for anonymous FTP connections is now changed to be
+  "ftp@example.com".
+
+- Robert A. Monat made libcurl build fine with VC2005 - it doesn't have
+  gmtime_r() like the older VC versions. He also made use of some machine-
+  specific defines to differentiate the "OS" define.
+
+Daniel (12 February 2007)
+- Rob Crittenden added support for NSS (Network Security Service) for the
+  SSL/TLS layer. http://www.mozilla.org/projects/security/pki/nss/
+
+  This is the fourth supported library for TLS/SSL that libcurl supports!
+
+- Shmulik Regev fixed so that the final CRLF of HTTP response headers are sent
+  to the debug callback.
+
+- Shmulik Regev added CURLOPT_HTTP_CONTENT_DECODING and
+  CURLOPT_HTTP_TRANSFER_DECODING that if set to zero will disable libcurl's
+  internal decoding of content or transfer encoded content. This may be
+  preferable in cases where you use libcurl for proxy purposes or similar. The
+  command line tool got a --raw option to disable both at once.
+
+- release tarballs made with maketgz will from now on have a LIBCURL_TIMESTAMP
+  define set to hold the exact date and time of when the tarball was built, as
+  a human readable string using the UTC time zone.
+  
+- Jeff Pohlmeyer fixed a flaw in curl_multi_add_handle() when adding a handle
+  that has an easy handle present in the "closure" list pending closure.
+
+Daniel (6 February 2007)
+- Regular file downloads wiht SFTP and SCP are now done using the non-blocking
+  API of libssh2, if the libssh2 headers seem to support them. This will make
+  SCP and SFTP much more responsive and better libcurl citizens when used with
+  the multi interface etc.
+
+Daniel (5 February 2007)
+- Michael Wallner added support for CURLOPT_TIMEOUT_MS and
+  CURLOPT_CONNECTTIMEOUT_MS that, as their names suggest, do the timeouts with
+  millisecond resolution. The only restriction to that is the alarm()
+  (sometimes) used to abort name resolves as that uses full seconds. I fixed
+  the FTP response timeout part of the patch.
+
+  Internally we now count and keep the timeouts in milliseconds but it also
+  means we multiply set timeouts with 1000. The effect of this is that no
+  timeout can be set to more than 2^31 milliseconds (on 32 bit systems), which
+  equals 24.86 days.  We probably couldn't before either since the code did
+  *1000 on the timeout values on several places already.
+
+Daniel (3 February 2007)
+- Yang Tse fixed the cookie expiry date in several test cases that started to
+  fail since they used "1 feb 2007"...
+
+- Manfred Schwarb reported that socks5 support was broken and help us pinpoint
+  the problem. The code now tries harder to use httproxy and proxy where
+  apppropriate, as not all proxies are HTTP...
+
+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

   Changelog for the c-ares project
 
+* February 19
+
+- Vlad Dinulescu added ares_parse_ns_reply().
+
+* February 13
+
+- 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.
+
+* 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

+.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)

-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.

+
+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.
