 ChangeLog
===========

.. note:: It is strongly recommended you upgrade to Python 3.7, which
   fixes bugs in asyncio that caused an ever-growing open file count
   and memory consumption whilst serving clients.  Those problems
   should not occur with Python 3.7.


Version 1.11.0 (18 Apr 2019)
============================

* require aiorpcX 0.15.x
* require aiohttp 3.3 or higher; earlier versions had a problematic bug

  :func:`blockchain.transaction.get_merkle`

  variables :envvar:`COST_SOFT_LIMIT`, :envvar:`COST_HARD_LIMIT`, :envvar:`REQUEST_SLEEP`,

  with which they share some of their costs.  Prior cost is remembered across reconnects.
