+Daniel (8 March 2001)
+- "Transfer-Encoding: chunked" is no longer any trouble for libcurl. I've
+  added two source files and I've run some test downloads that look fine.
+
+Daniel (5 March 2001)
+- The current 57 test cases now pass OK. It would suggest that libcurl works
+  using the old-style with one connection per handle. The test suite doesn't
+  handle multiple connections yet so there are no test cases for this.
+
+- I patched the telnet.c heavily to not use any global variables anymore. It
+  should make it a lot nicer library-wise.
+
+- The file:// support was modified slightly to use the internal connect-first-
+  then-do approach.
+
+Daniel (4 March 2001)
+- More bugs erased.
+
+Version 7.7-alpha2
+
+Daniel (4 March 2001)
+- Now, there's even a basic check that a re-used connection is still alive
+  before it is assumed so. A few first tests have proven that libcurl will
+  then re-connect instead of re-use the dead connection!
+
+Daniel (2 March 2001)
+- Now they work intermixed as well. Major coolness!
+
+- More fiddling around, my 'tiny' client I have for testing purposes now has
+  proved to download both FTP and HTTP with persistant connections. They do
+  not work intermixed yet though.
+
+Daniel (1 March 2001)
+- Wilfredo Sanchez pointed out a minor spelling mistake in a man page and that
+  curl_slist_append() should take a const char * as second argument. It does
+  now.
+
+Daniel (22 February 2001)
+- The persistant connections start to look good for HTTP. On a subsequent
+  request, it seems that libcurl now can pick an already existing connection
+  if a suitable one exists, or it opens a new one.
+
+- Douglas R. Horner mailed me corrections to the curl_formparse() man page
+  that I applied.
+
+Daniel (20 February 2001)
+- Added the docs/examples/win32sockets.c file for our windows friends.
+
+- Linus Nielsen Feltzing provided brand new TELNET functionality and
+  improvements:
+
+  * Negotiation is now passive. Curl does not negotiate until the peer does.
+  * Possibility to set negotiation options on the command line, currently only
+    XDISPLOC, TTYPE and NEW_ENVIRON (called NEW_ENV).
+  * Now sends the USER environment variable if the -u switch is used.
+  * Use -t to set telnet options (Linus even updated the man page, awesome!)
+
+- Haven't done this big changes to curl for a while. Moved around a lot of
+  struct fields and stuff to make multiple connections get connection specific
+  data in separate structs so that they can co-exist in a nice way. See the
+  mailing lists for discussions around how this is gonna be implemented. Docs
+  and more will follow.
+
+  Studied the HTTP RFC to find out better how persistant connections should
+  work. Seems cool enough.
+
+Daniel (19 February 2001)
+- Bob Schader brought me two files that help set up a MS VC++ libcurl project
+  easier. He also provided me with an up-to-date libcurl.def file.
+
+- I moved a bunch of prototypes from the public <curl/curl.h> file to the
+  library private urldata.h. This is because of the upcoming changes. The
+  low level interface is no longer being planned to become reality.
+
+Daniel (15 February 2001)
+- CURLOPT_POST is not required anymore. Just setting the POST string with
+  CURLOPT_POSTFIELDS will switch on the HTTP POST. Most other things in
+  libcurl already works this way, i.e they require only the parameter to
+  switch on a feature so I think this works well with the rest. Setting a NULL
+  string switches off the POST again.
+
+- Excellent suggestions from Rich Gray, Rick Jones, Johan Nilsson and Bjorn
+  Reese helped me define a way how to incorporate persistant connections into
+  libcurl in a very smooth way. If done right, no change may have to be made
+  to older programs and they will just start using persistant connections when
+  applicable!
+
+Daniel (13 February 2001)
+- Changed the word 'timeouted' to 'timed out' in two different error messages.
+  Suggested by Larry Fahnoe.
+
+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.

-Interfaces
-
- libcurl currently offers two different interfaces to the URL transfer
- engine. They can be seen as one low-level and one high-level, in the sense
- that the low-level one will allow you to deal with a lot more details but on
- the other hand not offer as many fancy features (such as Location:
- following). The high-level interface is supposed to be a built-in
- implementation of the low-level interface. You will not be able to mix
- function calls from the different layers.
-
- As we currently ONLY support the high-level interface, the so called easy
- interface, I will not attempt to describe any low-level functions at this
- point.
-
-Function descriptions

- The interface is meant to be very simple for very simple
- implementations. Thus, we have minimized the number of entries.

+Portability
+
+ libcurl works *exactly* the same, on any of the platforms it compiles and
+ builds on.
+
+ There's only one caution, and that is the win32 platform that may(*) require
+ you to init the winsock stuff before you use the libcurl functions. Details
+ on this are noted on the curl_easy_init() man page.
+
+ (*) = it appears users of the cygwin environment gets this done
+       automatically.
+
+Persistant Connections
+
+ With libcurl 7.7, persistant connections were added. Persistant connections
+ means that libcurl can re-use the same connection for several transfers, if
+ the conditions are right.
+
+ libcurl will *always* attempt to use persistant connections. Whenever you use
+ curl_easy_perform(), libcurl will attempt to use an existing connection to do
+ the transfer, and if none exists it'll open a new one that will be subject
+ for re-use on a possible following call to curl_easy_perform().
+
+ To allow libcurl to take full advantage of persistant connections, you should
+ do as many of your file transfers as possible using the same curl
+ handle. When you call curl_easy_cleanup(), all the possibly open connections
+ held by libcurl will be closed and forgotten.
+
+ Note that the options set with curl_easy_setopt() will be used in on every
+ repeat curl_easy_perform() call
+
+Compatibility with older libcurls
+
+ Repeated curl_easy_perform() calls on the same handle were not supported in
+ pre-7.7 versions, and caused confusion and defined behaviour.

-For the future
+ Things to do in project cURL. Please tell me what you think, contribute and
+ send me patches that improve things!
 
- Ok, this is what I wanna do with Curl. Please tell me what you think, and
- please don't hesitate to contribute and send me patches that improve this
- product! (Yes, you may add things not mentioned here, these are just a
- few teasers...)
+To do for the 7.7 release:
+
+ * Fix the random seeding. Add --egd-socket and --random-file options to the
+   curl client and libcurl curl_easy_setopt() interface.
+
+ * Support persistant connections (fully detailed elsewhere)
+
+ * Add a special connection-timeout that only goes for the connection phase.
+
+To do for the 7.8 release:
 
  * Make SSL session ids get used if multiple HTTPS documents from the same
    host is requested.
 
- * Make the curl tool support URLs that start with @ that would then mean that
-   the following is a plain list with URLs to download. Thus @filename.txt
-   reads a list of URLs from a local file. A fancy option would then be to
-   support @http://whatever.com that would first load a list and then get the
-   URLs mentioned in the list. I figure -O or something would have to be
-   implied by such an action.
+To do in a future release:
 
- * Improve the regular progress meter with --continue is used. It should be
-   noticable when there's a resume going on.
+ * Extend the test suite to include telnet and https. The telnet could just do
+   ftp or http operations (for which we have test servers) and the https would
+   probably work against/with some of the openssl tools.
 
  * Add a command line option that allows the output file to get the same time
-   stamp as the remote file. We already are capable of fetching the remote
+   stamp as the remote file. libcurl already is capable of fetching the remote
    file's date.
 
  * Make the SSL layer option capable of using the Mozilla Security Services as
    an alternative to OpenSSL:
    http://www.mozilla.org/projects/security/pki/nss/
 
- * Make sure the low-level interface works. highlevel.c should basically be
-   possible to write using that interface. Document the low-level interface
-
- * Make the easy-interface support multiple file transfers. If they're done
-   to the same host, they should use persistant connections or similar.
-   Figure out a nice design for this.
-
  * Add asynchronous name resolving, as this enables full timeout support for
    fork() systems.
 
+ * Non-blocking connect(), also to make timeouts work on windows.

  * Move non-URL related functions that are used by both the lib and the curl
    application to a separate "portability lib".

- *
- * This function asks for the particular document, file or resource that

- * just an absolute path or even a relative path. That means, if you're just
- * getting one file from the remote site, you can use the same URL as input
- * for both curl_open() as well as for this function.
- *
- * In the even there is a host name, port number, user name or password parts
- * in the URL, you can use the 'flags' argument to ignore them completely, or
- * at your choice, make the function fail if you're trying to get a URL from
- * different host than you connected to with curl_connect().
- *
- * You can only get one document at a time using the same connection. When one
- * document has been received you can although request again.
- *
- * When the transfer is done, curl_done() MUST be called.

+   The chunked encoding modifies the body of a message in order to

+
+   The chunk-size field is a string of hex digits indicating the size of
