Eventlet

=====
* GreenPipe is now a context manager (thanks, quad)
* tpool.Proxy supports iterators properly
* bug fixes in eventlet.green.os (thanks, Benoit)
* much code cleanup from Tavis
* a few more example apps
* multitudinous improvements in Py3k compatibility from amajorek

=====
* new EVENTLET_HUB environment variable allows you to select a hub without code
* improved GreenSocket and GreenPipe compatibility with stdlib
* bugfixes on GreenSocket and GreenPipe objects
* code coverage increased across the board
* Queue resizing
* internal DeprecationWarnings largely eliminated
* tpool is now reentrant (i.e., can call tpool.execute(tpool.execute(foo)))
* more reliable access to unpatched modules reduces some race conditions when monkeypatching
* completely threading-compatible corolocal implementation, plus tests and enthusiastic adoption
* tests stomp on each others' toes less
* performance improvements in timers, hubs, greenpool
* Greenlet-aware profile module courtesy of CCP
* support for select26 module's epoll
* better PEP-8 compliance and import cleanup
* new eventlet.serve convenience function for easy TCP servers

=====
* support psycopg in db_pool
* smart patcher that does the right patching when importing without needing to understand plumbing of patched module
* patcher.monkey_patch() method replacing util.wrap_*
* monkeypatch threading support
* removed api.named
* imported timeout module from gevent, replace exc_after and with_timeout()
* replace call_after with spawn_after; this is so that users don't see the Timer class
* added cancel() method to GreenThread to support the semantic of "abort if not already in the middle of something"
* eventlet.green.os with patched read() and write(), etc
* moved stuff from wrap_pipes_with_coroutine_pipe into green.os
* eventlet.green.subprocess instead of eventlet.processes
* improve patching docs, explaining more about patcher and why you'd use eventlet.green
* better documentation on greenpiles
* deprecate api.py completely
* deprecate util.py completely
* deprecate saranwrap
* performance improvements in the hubs
* much better documentation overall
* new convenience functions: eventlet.connect and eventlet.listen. Thanks, Sergey!

=====
* Deprecated coros.Queue and coros.Channel (use queue.Queue instead)
* Added putting and getting methods to queue.Queue.
* Added eventlet.green.Queue which is a greened clone of stdlib Queue, along with stdlib tests.
* Changed __init__.py so that the version number is readable even if greenlet's not installed.
* Bugfixes in wsgi, greenpool

=====

* Moved primary api module to __init__ from api. It shouldn't be necessary to import eventlet.api anymore; import eventlet should do the same job.
* Proc module deprecated in favor of greenthread
* New module greenthread, with new class GreenThread.
* New GreenPool class that replaces pool.Pool.
* Deprecated proc module (use greenthread module instead)
* tpooled gethostbyname is configurable via environment variable EVENTLET_TPOOL_GETHOSTBYNAME
* Removed greenio.Green_fileobject and refactored the code therein to be more efficient. Only call makefile() on sockets now; makeGreenFile() is deprecated. The main loss here is that of the readuntil method. Also, Green_fileobjects used to be auto-flushing; flush() must be called explicitly now.
* Added epoll support
* Improved documentation across the board.
* New queue module, API-compatible with stdlib Queue
* New debug module, used for enabling verbosity within Eventlet that can help debug applications or Eventlet itself.
* Bugfixes in tpool, green.select, patcher
* Deprecated coros.execute (use eventlet.spawn instead)
* Deprecated coros.semaphore (use semaphore.Semaphore or semaphore.BoundedSemaphore instead)
* Moved coros.BoundedSemaphore to semaphore.BoundedSemaphore
* Moved coros.Semaphore to semaphore.Semaphore
* Moved coros.event to event.Event
* Deprecated api.tcp_listener, api.connect_tcp, api.ssl_listener
* Moved get_hub, use_hub, get_default_hub from eventlet.api to eventlet.hubs
* Renamed libevent hub to pyevent.
* Removed previously-deprecated features tcp_server, GreenSSL, erpc, and trap_errors.
* Removed saranwrap as an option for making db connections nonblocking in db_pool.

=====

* Bugfix for wsgi.py where it was improperly expecting the environ variable to be a constant when passed to the application.
* Tpool.py now passes its tests on Windows.
* Fixed minor performance issue in wsgi.
