libssh2 - SSH2 library
======================
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
-----------
