• Windows/Python 3: Finish porting the gevent.subprocess module, fixing a large number of failing tests. Examples of failures are in issue #668 and issue #669 reported by srossross.
• Python 3: The SSLSocket class should return an empty bytes object on an EOF instead of a str. Fixed in pull request #674 by Dahoon Kim.
• Python 2: Workaround a buffering bug in the stdlib io module that caused FileObjectPosix to be slower than necessary in some cases. Reported in issue #675 by WGH-.
• PyPy: Fix a crash. Reported in issue #676 by Jay Oster.
  Caution There are some remaining, relatively rare, PyPy crashes, but their ultimate cause is unknown (gevent, CFFI, greenlet, the PyPy GC?). PyPy users can contribute to issue #677 to help track them down.
  PyPy: Exceptions raised while handling an error raised by a loop callback function behave like the CPython implementation: the exception is printed, and the rest of the callbacks continue processing.
• If a Hub object with active watchers was destroyed and then another one created for the same thread, which itself was then destroyed with destroy_loop=True, the process could crash. Documented in issue #237 and fix based on pull request #238, both by Jan-Philip Gehrcke.
• Python 3: Initializing gevent’s hub for the first time in a native background thread created during import could fail with AttributeError and ImportError. Reported in issue #687 by Gregory Petukhov.
