+
+Version 0.10
+------------
+
+  Added developer debugging hooks.  See --enable-debug-* options to ./configure

+
+  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)

+
+
+Version 0.6

+
+  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 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
+
