Notable changes
===============

This release solves an issue where nodes that did not follow the Heartwood activation on testnet (by running a version prior to v2.1.2) but then upgraded to v2.1.2 or later would be incapable of rolling back and following the Heartwood activation without performing a reindex operation.

Changelog
