* (February 15 2010) Daniel Stenberg:
- Added 46 new man pages for public convenience macros. The man pages are
just short redirects to the actual underlying function. The were all
initially created by a script.
- Committed the patch by Yoichi Iwaki in bug #2929647, which fixed a memory
leak when an 'outbuf' was still allocated when a session was freed.

servers (configured with a positive ClientAliveInterval) would
terminate connections against libssh2 clients because libssh2 did
not respond properly to the request. By Simon Josefsson.
Version 1.2.2 (November 16, 2009)
* This release includes the following changes:
o Fix crash when server sends an invalid SSH_MSG_IGNORE message.
Reported by Bob Alexander <balexander@expressor-software.com> in
<http://thread.gmane.org/gmane.network.ssh.libssh2.devel/2530>.
By Simon Josefsson.
o Support for the "aes128-ctr", "aes192-ctr", "aes256-ctr" ciphers
as per RFC 4344 for libgcrypt and OpenSSL. They are now the
preferred ciphers. By Simon Josefsson.
o Support for the "arcfour128" cipher as per RFC 4345 for libgcrypt
and OpenSSL. It is preferred over the normal "arcfour" cipher
which is somewhat broken. By Simon Josefsson.
o Add support for GCC visibility features. By Cristian Rodríguez.
o Fix libssh2_channel_forward_accept. By Juzna.
o Generate Win32 files correctly. By Peter Stuge.

o added gettimeofday() function for win32 for the debug trace outputs
o transport layer bug causing invalid -39 (LIBSSH2_ERROR_BAD_USE) errors
o scp examples now loop correctly over libssh2_channel_write()
* (August 29 2009) Daniel Stenberg:
- I fixed all code to use the recently added dedicated linked list functions
instead of doing the same stuff spread out all over.
- I also fixed a few cases where local variables where used to keep memory
but was used to keep state for re-invokes due to non-blocking situations
which would lead to segfaults.
Version 1.2 (August 10, 2009)
-----------------------------
* (August 02 2009) Alexander Lamaison:
- changed _libssh2_rsa_new_private and _libssh2_rsa_new_private so that they
no longer use the OpenSSL functions that take a FILE* argument. Passing
CRT-created objects across a DLL boundary causes crashes on Windows of the
DLL and the client aren't linked to the exact same verison of the CRT. Now
we pass the keys as strings to avoid this issue.
* (May 29 2009) Daniel Stenberg:
- Updated the knownhost API and there are now 9 functions, and all of them
have man pages. The libssh2.h now defines HAVE_LIBSSH2_KNOWNHOST_API to
ease things for applications to check for the correct release before trying
to use it.
* (May 23 2009) Daniel Stenberg:
- Anonymous bug report #2795816 revealed that doing subsequent
libssh2_sftp_init() calls on the same session failed.
* (May 20 2009) Daniel Stenberg:
- made libssh2_sftp_write() properly deal with huge/any sized input buffers.
- fixed libssh2_channel_write_ex() to return the correct return code, and
deal with sending off huge buffers better
* (May 7 2009) Daniel Stenberg:
- linked list code. I got a bit tired of the fact that we don't have any
generic linked-list functions within libssh2 so I wrote up the first embryo
for one that I use for this new functionality. The plan would then be to
move all existing code that uses linked lists to use this new set.
- base64 encode. I had to add a base64 encoding function which was missing
in the code base so it helps to "bloat" my patch.
- The knownhost API is currently:
_init() - init a bundle of known hosts
_add() - add a known host
_del() - delete a known host
_free() - free an entire bundle of known hosts
_check() - check if a host+key is present in the bundle
The convenience function:
_parsefile() - reads a ~/.ssh/known_hosts file and add all entries to the
given bundle
- there's no docs other than some comments in the code/headers yet
- the patch includes changes to example/simple/ssh2_exec.c that makes use of
a few of these functions. Using that I've verified that the functions in
fact can verify my localhost's key agains my ~/.ssh/known_hosts file
* (Apr 30 2009) Daniel Stenberg:
Markus posted a bug report about a bad 0-return from libssh2_channel_read:
http://libssh2.haxx.se/mail/libssh2-devel-archive-2009-04/0076.shtml
And it was indeed a bad loop that terminated too early due to a receveived
close packet.
* (Apr 14 2009) Daniel Stenberg:
libssh2_poll() and libssh2_poll_channel_read() are now considered and
documented deprecated and they will be removed at next soname bump. It also
saves us from fixing some rather quirky bugs in libssh2_poll()...
Version 1.1 (April 2, 2009)
---------------------------
- (Mar 28 2009) Daniel Stenberg:
Jean-Louis Charton found a memory leak in
libssh2_userauth_hostbased_fromfile_ex()
- (Mar 25 2009) Daniel Stenberg:
* Renamed the functions in src/transport.c to be _libssh2_transport_ prefixed
and introduced a transport.h header.
* Fixed the blocking mode to only change behavior not the actual underlying
socket mode so we now always work with non-blocking sockets. This also
introduces a new rule of thumb in libssh2 code: we don't call the
external function calls internally. We use the internal (non-blocking)
ones!
* libssh2_channel_receive_window_adjust2 was added and
libssh2_channel_receive_window_adjust is now deprecated
* Introduced "local" header files with prototypes etc for different parts
instead of cramming everything into libssh2_priv.h. channel.h is the
first.
- (Mar 19 2009) Daniel Stenberg: based on a patch by "E L" we now use errno
properly after recv() and send() calls (that internally are now known as
_libssh2_recv() and _libssh2_send()) so that the API and more works fine on
windows too!
- (Mar 17 2009) Simon Josefsson:
Added a Libtool -export-symbols-regex flag to reduce the number of
exported symbols in shared libraries. Reported by Mikhail Gusarov.
- (Mar 16 2009) Daniel Stenberg:
I renamed a few man pages to match the exact name of the functions they
describe. I also added template versions for the 13 functions that
previously lacked man pages. While these don't contain any docs just yet, it
will now be easier to add the info as the foundation is there!
- (Mar 15 2009) Daniel Stenberg:
* libssh2_channel_read_ex() was simplified and enhanced. It now adjusts the
window less frequent and uses much larger window that now allows MUCH
faster transfers.
* SCP send/recv now allow file names with whitespaces etc, thanks to a patch
by Heiner Steven
- (Mar 13 2009) Daniel Stenberg: Cleanups, that do seem to have boosted SFTP
download performance up to 300% in some tests:
* cut off "_ex" from several internal function names
* corrected some log outputs
* simplified libssh2_channel_read_ex() and made it much faster in the process
* cut out {{{ and }}} comments that were incorrect anyway
* fixed sftp_packet_ask() to return the correct packet by using memcmp() and
not strncmp()
* fixed mkdir()'s wait for packet to use the correct request_id - it
semi-worked previously because strncmp() in sftp_packet_ask() made it
match far too easily.
* took away the polling functionality from sftp_packet_ask() since it wasn't
used
- (Mar 7 2009) Olivier Hervieu pointed out a flaw in the
libssh2_channel_x11_req_ex() function that made it produce a crappy random
chunk of data. Peter Stuge improved the fix to not do out-of-boundary
writes. I (Daniel Stenberg) replaced the snprintf() with a plain sprintf()
since the size argument wasn't adding anything anyway.
- (Feb 23 2009) Added libssh2_version()
- (Feb 20 2009) libssh2_channel_direct_tcpip_ex() bug #1902169 fixed, which
caused it to fail when called a second time.
- (Feb 12 2009) Romain Bondue extended Markus Moeller fix from Feb 8, based on
a previous (uncommitted) patch by Erik Brossler. It improves
libssh2_channel_write_ex in blocking situations when the socket is set non-
blocking.
- (Feb 8 2009) Markus Moeller fixed a flaw in libssh2_channel_write_ex() that
would occur on EAGAIN situations.
Version 1.0 (December 26 2008)
------------------------------
- (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()

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.

Fixed KEX_INIT cookie and packet padding to use actual random data
Added DESTDIR support to makefiles (Adam Go³êbiowski -- I hope that
character set translates right)

and libssh2_channel_forward_accept().
Added ./configure option '--disable-gex-new' to allow using the older
group-exchange format
Added MAC methods hmac-md5 and hmac-md5-96.
Version 0.4
-----------
Fixed crash when trying to free sftp_dirhandle data from a filehandle struct.
Fixed leak in sftp_open_ex(), handle->handle not freed in handle_close().

Version 0.2
-----------
Changed extended data ignorance mechanism:
libssh2_channel_ignore_extended_data() changed to libssh2_channel_handle_extended_data()
Macro introduced for backward compatability during beta phase.
*** THE LIBSSH2_CHANNEL_IGNORE_EXTENDED_DATA() MACRO WILL BE REMOVED PRIOR TO 1.0 RELEASE ***
libssh2_channel_handle_extended_data() may be passed one of three "ignore_mode" constants
LIBSSH2_CHANNEL_EXTENDED_DATA_NONE Default behavior, queue ED packets and return them with read_ex
LIBSSH2_CHANNEL_EXTENDED_DATA_IGNORE Equivalent to libssh2_channel_ignore_extended_data()
IGNORE will implicitly flush the extended data stream(s)
LIBSSH2_CHANNEL_EXTENDED_DATA_MERGE Calls to channel_read() will check both the standard data stream
and the extended data stream(s) for the first available packet
Changed libssh2_session_disconnect_ex() to return an error code when alloc fails
Added libssh2_channel_flush_ex() and basic macros: ..._flush() ..._flush_stderr()
flush_ex accepts either the streamid (0 for standard data, 1 for stderr) or one of the two following constants:
LIBSSH2_CHANNEL_FLUSH_ALL Flush all streams
LIBSSH2_CHANNEL_FLUSH_EXTENDED_DATA Flush all streams EXCEPT the standard data stream
