                                History of Changes
 
+Version 7.6.1
+
+Daniel (9 February 2001)
+- Frank Reid and Cain Hopwood provided information and research around a HTTPS
+  PUT/upload problem we seem to have. No solution found yet.
+
+Daniel (8 February 2001)
+- An interesting discussion is how to specify an empty password without having
+  curl ask for it interactively? The current implmentation takes an empty
+  password as a request for a password prompt. However, I still want to
+  support a blank user field. Thus, today if you enter "-u :" (without user
+  and password) curl will prompt for the password. Tricky. How would you
+  specify you want the prompt otherwise?
+
+- Made the netrc parse result possible to use for other protocols than FTP and
+  HTTP (such as the upcoming TELNET fixes).
+
+- The previously mentioned "MSVC++ problems" turned out to be a non-issue.
+
+- Added a HTTP file upload code example in the docs/examples/ section on
+  request.
+
+- Adjusted the FTP response fix slightly.
+
+Version 7.6.1-pre3
+
+Daniel (7 February 2001)
+- SM found a flaw in the response reading function for FTP that could make
+  libcurl not get out of the loop properly when it should, if libcurl got -1
+  returned when reading the socket.
+
+- I found a similar mistake in http.c when using a proxy and reading the
+  results from the proxy connection.
+
+Daniel (6 February 2001)
+- A friendly person named "SM" (nntp at iname.com) pointed out that the VC
+  makefile in src/ needed the libpath set for the debug build to work.
+
+- Daniel Gehriger stepped in to assist with the VC++ stuff Robert Weaver
+  brought up yesterday.
+
+Daniel (5 February 2001)
+- Jun-ichiro itojun Hagino brought a big patch that brings IPv6-awareness to
+  a bunch of different areas within libcurl.
+
+- Robert Weaver told me about the problems the MS VC++ 6.0 compiler has with
+  the 'static' keyword on a number of libcurl functions. I might need to add a
+  patch that redefines static when libcurl is compiled with that compiler.
+  How do I know when VC++ compiles, anyone?
+
+Daniel (4 February 2001)
+- curl_getinfo() was extended with two new options:
+  CURLINFO_CONTENT_LENGTH_DOWNLOAD and CURLINFO_CONTENT_LENGTH_UPLOAD. They
+  return the full assumed content length of the transfer in the given
+  direction. The CURLINFO_CONTENT_LENGTH_DOWNLOAD will be the Content-Length:
+  size of a HTTP download. Added descriptions to the man page as well. This
+  was done after discussions with Bob Schader.
+
+Daniel (3 February 2001)
+- Ingo Ralf Blum provided another fix that makes curl build under the more
+  recent cygwin installations. It seems they've changed the preset defines to
+  not include WIN32 anymore.
+
+Version 7.6.1-pre2
+
+Daniel (31 January 2001)
+- Curl_read() and curl_read() now return a ssize_t for the size, as it had to
+  be able to return -1. The telnet support crashed due to this and there was a
+  possibility to weird behaviour all over. Linus Nielsen Feltzing helped me
+  find this.
+
+- Added a configure.in check for a working getaddrinfo() if IPv6 is requested.
+  I also made the configure script feature --enable-debug which sets a couple
+  of compiler options when used. It assumes gcc.
+
+Daniel (30 January 2001)
+- I finally took a stab at the long-term FIXME item I've had on myself, and
+  now libcurl will properly work when doing a HTTP range-request that follows
+  a Location:. Previously that would make libcurl fail saying that the server
+  doesn't seem to support range requests.
+
+Daniel (29 January 2001)
+- I added a test case for the HTTP PUT resume thing (test case 33).
+
+Version 7.6.1-pre1
+
+Daniel (29 January 2001)
+- Yet another Content-Range change. Ok now? Bob Schader checks from his end 
+  and it works for him.
+
+Daniel (27 January 2001)
+- So the HTTP PUT resume fix wasn't good. There should appearantly be a
+  Content-Range header when resuming a PUT.
+
+- I noticed I broke the download-check that verifies that a resumed HTTP
+  download is actually resumed. It got broke because my new 'httpreq' field
+  in the main curl struct. I should get slapped. I added a test case for
+  this now, so I won't be able to ruin this again without noticing.
+
+- Added a test case for content-length verifying when downloading HTTP.
+
+- Made the progress meter title say if the transfer is being transfered. It
+  makes the output slightly better for resumes.
+
+- When dealing with Location: and HTTP return codes, libcurl will not attempt
+  to follow the spirit of RFC2616 better. It means that when POSTing to a
+  URL that is being following to a second place, the standard will judge on
+  what to do. All HTTP codes except 303 and 305 will cause curl to make a
+  second POST operation. 303 will make a GET and 305 is not yet supported.
+
+  I also wrote two test cases for this POST/GET/Location stuff.

+  3.9 How do I use curl in PHP?
+
+  PHP4 has the ability to use libcurl as an internal module if built with that
+  option enabled. You then get a set of extra functions that can be used
+  within your PHP programs. You find all details about those functions in the
+  curl section in the PHP manual, see the online version at:
+
+        http://www.php.net/manual/ref.curl.php
+
+  PHP also offers the option to run a command line, and then you can of course
+  invoke the curl tool using a command line. This is the way to use curl if
+  you're using PHP3 or PHP4 built without curl module support.
+
+  3.10 What about SOAP, WEBDAV, XML-RPC or similar protocols over HTTP?
+
+  Curl adheres to the HTTP spec, which basically means you can play with *any*
+  protocol that is built ontop of HTTP. Protocols such as SOAP, WEBDAV and
+  XML-RPC are all such ones. You can use -X to set custom requests and -H to
+  set custom headers (or replace internally generated ones).
+
+  Using libcurl or PHP's curl modules is just as fine and you'd just use the
+  proper library options to do the same.
