0.9.0
=====
Merged many eventlet-twisted integration patches by Denis Bilenko. It is now possible to mix eventlet-using code with twisted-using code.
Much of the core functionality has been refactored and cleaned up, including the removal of eventlet.greenlib. This means that it is now possible to use plain greenlets without modification in eventlet, and plain old subclasses of greenlet instead of the old eventlet.greenlib.GreenletContext. Calling eventlet.api.get_hub().switch() now checks to see whether the current greenlet has a "switch_out" method and calls it if so, providing the same functionality that the GreenletContext.swap_out used to. The swap_in behavior can be duplicated by overriding the switch method, and the finalize functionality can be duplicated by having a try: finally: block around the greenlet's main implementation. The eventlet.backdoor module has been ported to this new scheme, although it's signature had to change slightly so existing code that used the backdoor will have to be modified.
Monkey-patching is now no longer the default way to use eventlet. Instead, there are a series of standard library networking modules that have been patched to cooperate using the eventlet hub inside the eventlet.green module. For example, using "from eventlet.green import httplib" is equivalent to the old practice of doing "from eventlet import util; util.wrap_socket_with_coroutine_socket(); import httplib".
eventlet.httpd has been removed. Use eventlet.wsgi instead.
0.8.x
=====
Fix a CPU leak that would cause the poll hub to consume 100% CPU in certain conditions, for example the echoserver example. (Donovan Preston)
Fix the libev hub to match libev's callback signature. (Patch by grugq)
Add a backlog argument to api.tcp_listener (Patch by grugq)
0.7.x
=====
Fix a major memory leak when using the libevent or libev hubs. Timers were not being removed from the hub after they fired. (Thanks Agusto Becciu and the grugq). Also, make it possible to call wrap_socket_with_coroutine_socket without using the threadpool to make dns operations non-blocking (Thanks the grugq).
It's now possible to use eventlet's SSL client to talk to eventlet's SSL server. (Thanks to Ryan Williams)
Fixed a major CPU leak when using select hub. When adding a descriptor to the hub, entries were made in all three dictionaries, readers, writers, and exc, even if the callback is None. Thus every fd would be passed into all three lists when calling select regardless of whether there was a callback for that event or not. When reading the next request out of a keepalive socket, the socket would come back as ready for writing, the hub would notice the callback is None and ignore it, and then loop as fast as possible consuming CPU.
0.6.x
=====
Fixes some long-standing bugs where sometimes failures in accept() or connect() would cause the coroutine that was waiting to be double-resumed, most often resulting in SwitchingToDeadGreenlet exceptions as well as weird tuple-unpacking exceptions in the CoroutinePool main loop.
0.6.1: Added eventlet.tpool.killall. Blocks until all of the threadpool threads have been told to exit and join()ed. Meant to be used to clean up the threadpool on exit or if calling execv. Used by Spawning.
0.5.x
=====
"The Pycon 2008 Refactor": The first release which incorporates libevent support. Also comes with significant refactoring and code cleanup, especially to the eventlet.wsgi http server. Docstring coverage is much higher and there is new extensive documentation: http://wiki.secondlife.com/wiki/Eventlet/Documentation
The point releases of 0.5.x fixed some bugs in the wsgi server, most notably handling of Transfer-Encoding: chunked; previously, it would happily send chunked encoding to clients which asked for HTTP/1.0, which isn't legal.
0.2
=====
Initial re-release of forked linden branch.
