and memory consumption whilst serving clients. Those problems
should not occur with Python 3.7.
Version 1.7.1 (28 Jul 2018)
============================
* switch to aiorpcX 0.5.8 which implements some curio task management
primitives on top of asyncio that make writing correct async code
much easier, as well as making it simpler to reason about
* use those primitives to restructure the peer manager, which is now
fully concurrent again, as well as the block processor and
controller
* fix `#534`_ introduced in 1.7
* minor coin tweaks (ghost43, cipig)
Version 1.7 (25 Jul 2018)
