-Version 0.16
+Version 0.18
 ------------
+
+- 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()
