libssh2 - SSH2 library
======================
Version 0.9
-----------
Changed blocking_read to only block as much as necessary and not an arbitrary length of time. (Thanks Felix)
Fixed SFTP INIT/VERSION to exclude request_id and send correct maximum version number.
Fixed SFTP to be properly BC with version 1 and 2 servers.
Fixed libssh2_poll() to recognized closed sessions/channels.
Fixed libssh2_channel_write_ex() to fully block when set to blocking mode. Return actual bytes written as well. (Thanks deadem)
Added libssh2_channel_window_read_ex() and libssh2_channel_window_write_ex()
for examining the ssh transport windowing states.
Version 0.8
-----------
Fix potential segfault in compression/decompression.
Fix compatability with older versions of OpenSSL
Swapped order of none,zlib compression modes to prefer no compression by default.
Added sys/uio.h for platforms (FBSD) which need it in order to define struct iovec.
Added libssh2_poll() to check status of sockets/channels/listeners.
Removed unnecessary inclusion of stdio.h (holdover from debugging)
Version 0.7
-----------
Added libssh2_userauth_hostbased_fromfile_ex() for authenticating from hostkey.
Added configure recognition for MacOSX (Darwin) (Thanks Gabe)
Fixed extended data identification in libssh2_channel_read().
Fixed window adjust code. Hadn't acknowledged adjustments correctly.
Removed initial_window_size requirement for sending window adjust packet.
Version 0.6
-----------
Added LIBSSH2_FLAG_SIGPIPE to enable/disable SIGPIPE generated by send()/recv() calls. Default off.
Added libssh2_session_flag() to set optional session flags.
Collapsed exchanging_keys/newkeys/authenticated flags into single state attribute.
Fix zlib compression issue when internal buffer state misses partial sync.
Fix segfault when libssh2_session_methods() is called prior to session_startup().
Fixed client to server channel windowing. Pervent send queue overruns.
Swapped banner send/receive order (send first, then wait for response).
Version 0.5
-----------
*** BC Break ***
Reimplemented libssh2_session_methods() to match libssh2_session_method_pref() style
Fixed libssh2_attr2bin() (effects any setstat style call).
Fixed authenticating with encrypted private key.
Fixed authenticating via ssh-dss public key.
Fixed KEX_INIT cookie and packet padding to use actual random data
Added DESTDIR support to makefiles (Adam Go<47><6F>biowski -- I hope that character set translates right)
Added libssh2_channel_forward_listen_ex(), libssh2_channel_forward_cancel(), 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().
Fixed leak in sftp_symlink_ex(), result for READLINK and REALPATH not freed unless there was an error.
Added libssh2_banner_set(), specify an arbitrary banner to send on introduction.
Version 0.3
-----------
Fixed libssh2_channel_read_ex(). Packet loop initialized BEFORE transport polled for new packets (should have been after).
Fixed blocking issues in scp_send()/scp_recv().
Fixed degree of indirection in macerror callback.
Changed packet read mechanism to use a fixed buffer and avoid unnecessary alloc/free calls. (especially while non-block looping)
Added channel close callback.
Added SFTP support (Using its own header file: libssh2_sftp.h)
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
Added libssh2_session_callback_set() for setting ignore/debug/disconnect/macerror callbacks
Added libssh2_session_method_pref() to selectively set methods and method preferences.
Added libssh2_session_methods() to determine what methods were negotiated.
Added libssh2_session_abstract() for retreiving &session->abstract
Added libssh2_session_last_error() for retreiving error codes/messages
