On behalf of the RelStorage contributors, I am pleased to announce the release of RelStorage 2.0.
RelStorage is a scalable backend for ZODB (an object-oriented database for Python that provides transparent object persistence) that allows you to use MySQL, PostgreSQL or Oracle to store your object data. For more, please see http://relstorage.readthedocs.io/
This major release of RelStorage brings full support for Python 3, ZODB/ZEO 4 and 5, PyPy and gevent.
This release also removes support for Python 2.6 and ZODB3. RelStorage 1.6.3 (2016-09-30) is the most recent release supporting these legacy platforms.
The complete list of changes is available at http://relstorage.readthedocs.io/en/latest/changelog.html
Although RelStorage's internals have been substantially changed, most users just relying on documented ZODB behaviour should find RelStorage 2.0 to be a drop-in replacement for 1.6 on supported platforms.
