@ -52,6 +52,7 @@ Changes in 2.0.3-alpha:
o Finally expose the IOCP-based bufferevent backend. It passes its unit tests, but probably still has some bugs remaining. Code by Nick Mathewson and Christopher Davis.
o Numerous other bugfixes.
o On FreeBSD and other OSes, connect can return ECONREFUSED immediately; instead of failing the function call, pretend with faileld in the callback.
o Fix a race condition in the pthreads test case; found by Nick Mathewson
Changes in 2.0.2-alpha:
o Add a new flag to bufferevents to make all callbacks automatically deferred.
