v0.94.4 Hammer (draft)
======================

This Hammer point fixes several important bugs in Hammer, as well as
fixing interoperability issues that are required before an upgrade to
Infernalis. That is, all users of earlier version of Hammer or any
version of Firefly will first need to upgrade to hammer v0.94.4 or
later before upgrading to Infernalis (or future releases).

All v0.94.x Hammer users are strongly encouraged to upgrade.
