+---------------------
+ * added SSH-agent support (for posix) from john rochester
+ * added chdir() and getcwd() to SFTPClient, to emulate a "working directory"

+ to die on all platforms except osx
+ * added a potential workaround for windows to let Channel.fileno() (and
+ therefore the select module) work!
+ * changed API for subsystem handlers (sorry!) to pass more info and make it
+ easier to write a functional SFTP server
+
+v1.2 (lapras) 28feb05
+---------------------
+ * added SFTPClient.listdir_attr() for fetching a list of files and their
+ attributes in one call
+ * added Channel.recv_exit_status() and Channel.send_exit_status() for
+ manipulating the exit status of a command from either client or server
+ mode
+ * moved check_global_request into ServerInterface, where it should've been
+ all along (oops)
+ * SFTPHandle's default implementations are fleshed out more
+ * made logging a bit more consistent, and started logging thread ids

+ * fixed bug where closing a Channel could end up killing the entire
+ Transport
+ * actually include demo_windows.py this time (oops!)

+ would generate the wrong hash (and therefore fail the initial handshake)
+ * server-mode subsystem handler is a bit more flexible
+
+v0.9 (ivysaur) 22oct04
+----------------------
+ * new ServerInterface class for implementing server policy, so it's no
+ longer necessary to subclass Transport or Channel -- server code will
+ need to be updated to follow this new API! (see demo_server.py)
+ * some bugfixes for re-keying an active session
+ * Transport.get_security_options() allows fine-tuned control over the
+ crypto negotiation on a new session
+ * Transport.connect() takes a single hostkey object now instead of two
+ string parameters

+ success or False on failure

+ class to be subclassed: SubsystemHandler)

+ * now imports UTF-8 encodings explicitly as a hint to "freeze" utilities
+ * no longer rejects older SFTP servers
+ * default packet size bumped to 8kB
+ * fixed deadlock in closing a channel
+ * Transport.connect() -- fixed bug where it would always fail when given a
+ host key to verify
+
+v0.9 (fearow) 23apr04
+---------------------
+ * Transport.send_ignore() -- send random ignored bytes
+ * RSAKey/DSSKey added from_private_key_file() as a factory constructor;
+ write_private_key_file() & generate() to create and save ssh2 keys;
+ get_base64() to retrieve the exported public key
+ * Transport added global_request() [client] and check_global_request()
+ [server]
+ * Transport.get_remove_server_key() now returns a PKey object instead of a
