+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.

+- 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().

+CURLMcode curl_multi_assign(CURLM *multi_handle, curl_socket_t sockfd,
+                            void *sockptr);
+.SH DESCRIPTION
+This function assigns an association in the multi handle between the given
+socket and a private pointer of the application. This is (only) useful for
+\fIcurl_multi_socket(3)\fP uses.
+
+When set, the \fIsockptr\fP pointer will be passed to all future socket
+callbacks for the specific \fIsockfd\fP socket.
+
+If the given \fIsockfd\fP isn't already in use by libcurl, this function will
+return an error.
+
+libcurl only keeps one single pointer associated with a socket, so calling
+this function several times for the same socket will make the last set pointer
+get used.
+
+The idea here being that this association (socket to private pointer) is
+something that just about every application that uses this API will need and
+then libcurl can just as well do it since it already has an internal hash
+table lookup for this.
+.SH "RETURN VALUE"
+The standard CURLMcode for multi interface error codes.
+.SH "TYPICAL USAGE"
+In a typical application you allocate a struct or at least use some kind of
+semi-dynamic data for each socket that we must wait for action on when using
+the \fIcurl_multi_socket(3)\fP approach.
+
+When our socket-callback get called by libcurl and we get to know about yet
+another socket to wait for, we can use \fIcurl_multi_assign(3)\fP to point out
+the particular data so that when we get updates about this same socket again,
+we don't have to find the struct associated with this socket by ourselves.

+Doing HTTP Pipelining with libcurl
+==================================
+
+Background
+
+Since pipelining implies that one or more requests are sent to a server before
+the previous response(s) have been received, it cannot be implemented easily
+into libcurl's easy interface due to its synchronous nature. We therefore only
+aim on adding it for multi interface use.
+
+Considerations
+
+When using the multi interface, you create one easy handle for each transfer.
+Bascially any number of handles can be created, added and used with the multi
+interface - simultaneously. It is an interface designed to allow many
+simultaneous transfers while still using a single thread.
+
+Pipelining however, will force us to allow apps to somehow "connect" two (or
+more) easy handles that are added to a multi handle. The first one sends a
+request and receives a response, just as normal, while the second (and
+subsequent) ones need to be attached to the first handle so that it can send
+its request on the same connection and then sit and wait until its response
+comes.
+
+API
+
+We add a new option to curl_multi_setopt() called CURLMOPT_PIPELINING that
+enables "attempted pipelining" and then all easy handles used on that handle
+will attempt to use an existing pipeline.
+
+Decisions Already Made
+
+- A pipeline is only created if a previous connection exists to the same IP
+  address that the new request is being made to use.
+
+- Pipelines are only supported for HTTP(S) as no other currently supported
+  protocol has features resemembling this, but we still name this feature
+  plain 'pipelining' to possibly one day support it for other protocols as
+  well.
+
+- HTTP Pipelining is for GET and HEAD requests only.
+
+- When a pipeline is in use, we must take precautions so that when used easy
+  handles (i.e those who still wait for a response) are removed from the multi
+  handle, we must deal with the outstanding response nicely.
+
+- Explicitly asking for pipelining handle X and handle Y won't be supported.
+  It isn't easy for an app to do this association. The lib should probably
+  still resolve the second one properly to make sure that they actually _can_
+  be considered for pipelining. Also, asking for explicit pipelining on handle
+  X may be tricky when handle X get a closed connection.
+
+To Ponder About
+
+- We need options to control max pipeline length, and probably how to behave
+  if we reach that limit. As was discussed on the list, it can probably be
+  made very complicated, so perhaps we can think of a way to pass all
+  variables involved to a callback and let the application decide how to act
+  in specific situations. Either way, these fancy options are only interesting
+  to work on when everything is working and we have working apps to test with.
+
+- Currently (before pipelining) we do not have any code or concept that lets
+  multiple handles share the same physical connection. We need to carefully
+  make sure that each easy handle knows exactly what they can do and when, on
+  the shared connection.
+
+- We need to keep a linked list of each handle that is part of a single pipe
+  so that if it breaks, we know which handles that need to resend their
+  requests. The pipe linked-lists could very well be "held" in the multi
+  handle struct so that they won't "belong" to a particular easy handle that
+  happens to be part of the pipeline during a certain period.
