-Version 
-------------
+Version 1.0 ( )
+-------------------------------
+
+- (Dec 20 2008) Based on Alexander Lamaison's patch, there's now a new
+  function called libssh2_sftp_tell64() that returns the 64 bit file offset,
+  as the existing libssh2_sftp_tell() only returns a size_t.
+
+- (Dec 18 2008) Markus Moeller fixed the issue also reported by Alexander
+  Lamaison which caused SFTP reads with large buffers to fail.
+
+- Several flaws were fixed that prevented at least SFTP to work reliably
+
+- Vlad Grachov brought the new function called
+  libssh2_session_block_directions() which returns a bitmask for what
+  directions the connection blocks. It is to be used applications that use
+  non-blocking sockets and when a libssh2 function returns
+  LIBSSH2_ERROR_EAGAIN this function can be used to figure out in which
+  direction the socket would block and thus it can wait for the socket to
+  again be ready for communication in that direction before it calls libssh2
+  again.
+
+- Vincent Jaulin brought the new libssh2_channel_request_pty_size_ex()
+  function.
+
+- Carlo Bramini fixed the build for msys+mingw. Bug #1943976.
+
+- Neil Gierman provided improved Visual Studio 2008 code in bug #1946268
+
+- Bug #1862727 fixed libssh2_poll() to work on windows (by defining
+  HAVE_SELECT).
+
+- Based on bug #1815692, we introduce libssh2_sftp_seek64() that allows
+  seeking beyond the 2GB margin even on 32bit machines.
+
+- Based on a patch in bug #1878059 by Steven Ayre libssh2 now parses >2GB file
+  sizes when downloading SCP files.
+
+- Bug #2064371 pointed out that the SSH2 banner may not use dash
+  ('-'). Reported by Bjorn Stenborg.
+
+- Sean Peterson fixed a key re-exchange bug:
+  http://daniel.haxx.se/projects/libssh2/mail/libssh2-devel-archive-2008-06/0002.shtml
+
+- Mike Protts filed the bug report #1908724 that identified and fixed a problem
+  with SFTP stat on files >4GB in size. Previously it used 32bit math only.
+
+- Removed a stderr debug message that was accidentally left in (bug #1863153)
+
+- OpenSSL and libz detection changed to make cross-compiling to Mingw
+  work.  See README for parameters to use if the auto-detection does
+  not work for you.  From Simon Josefsson.
+
+- Simon Josefsson added a self-test that uses libssh2 to connect to a
+  local sshd (only enabled if if OpenSSH is installed).
+
+Version 0.18 (November 11 2007)
+-------------------------------
+
+- Various changes that improve non-blocking operations and prevent stalls.
+  Especially noticable on Windows since libssh2 just didn't work properly
+  non-blocking on Windows before.
+
+- Peter O'Gorman reported how a SCP transfer would hang for him, and it was
+  fairly easy reproducable. One bug was in the transport layer, ignoring to
+  read more data while there was data left even though it couldn't decrypt the
+  data that was left due to it being too little... The other bug was in the
+  channel layer, where the libssh2_channel_receive_window_adjust() function
+  missed to set the state variables at times and thus this function would
+  misbehave on repeated invokes.
+
+- Changed the signature of libssh2_channel_setenv_ex to add const to the
+  "varname" parameter (Dan Fandrich)
+
+- Satish Mittal and David J Sullivan fixed an infinit recv() loop in
+  libssh2_banner_receive()
+
+Version 0.17 (August 6 2007)
+----------------------------
+Changes since previous version include:
+
+   o Re-indented the source code with this GNU indent setup:
+

+      --braces-after-struct-decl-line
+      --space-after-cast

+      --space-after-if
+      --space-after-while
+      --no-space-after-function-call-names
+
+Version 0.16 (August 6 2007)
+----------------------------
+Changes since previous version include:
+
+   o CRLF stripping fix for PEM reading
+   o libssh2_scp_recv() error message fix
+   o added HACKING as an initial attempt to describe our source code format
+   o new public defines in include/libssh2.h to allow applictions to figure out
+     version number etc
+   o new script (maketgz) to build releases with
+   o updated files for building with MSVC and mingw
+   o keyboard-interactive would always fail due to claimed memory problem
+   o a few minor memory leaks fixed
+   o libssh2_poll() no longer relies on C99 features
+   o AIX 4 and 5 now supports non-blocking sockets
+   o large file magic checks in configure
+   o LIBSSH2_APINO was removed from the public header file
+
+This release would not have been possible without these friendly contributors:
+
+   James Housley, Simon Josefsson, Dan Fandrich, Guenter Knauf and I too did
+   some poking. (Sorry if I forgot anyone I should've mentioned here.)
+
+Of course we would have nothing without the great work by Sara Golemon that 
+we're extending and building upon.

+This function is deemed DEPRECATED and will be removed from libssh2 in a

+
+Decode a base64 chunk and store it into a newly allocated buffer. 'dest_len'
+will be set to hold the length of the returned buffer that '*dest' will point
+to.
+
+The returned buffer is allocated by this function, but it is not clear how to

+The memory that *dest points to is allocated by the malloc function libssh2
+uses, but there's no way for an appliction to free this data in a safe and
+reliable way!

-Identify the current offset of the file handle's internal pointer. Note

-libssh2 implements this using a localized file pointer which is updated 
-with each read/write call.

+\fIsession\fP - Session instance as returned by 
+.BR libssh2_session_init(3)
+
+\fIusername\fP - Name of user to attempt plain password authentication for.
+
+\fIusername_len\fP - Length of username parameter.
+
+\fIresponse_callback\fP - As authentication proceeds, host issues several (1 or more) challenges and requires responses. This callback will be called at this moment. Callback is responsible to obtain responses for the challenges, fill the provided data structure and then return control. Responses will be sent to the host. String values will be free(3)ed by the library.
+
+Attempts keyboard-interactive (challenge/response) authentication.
+
+Note that many SSH servers will always issue single "password" challenge,
+requesting actual password as response, but it is not required by the protocol,
+and various authentication schemes, such as smartcard authentication may use
+keyboard-interactive authentication type too.
+
+.SH RETURN VALUE
+Return 0 on success or negative on failure.  It returns
+LIBSSH2_ERROR_EAGAIN when it would otherwise block. While
+LIBSSH2_ERROR_EAGAIN is a negative number, it isn't really a failure per se.
+
+.SH ERRORS
+\fILIBSSH2_ERROR_ALLOC\fP -  An internal memory allocation call failed.
+
+\fILIBSSH2_ERROR_SOCKET_SEND\fP - Unable to send data on socket.
