This is a maintenance release to fix a critical bug; we urge all users to upgrade.

Looking at the release notes, I don't understand which of the changes fixes a critical bug. Is this one of the OS X specific changes, or is it about a bug that affects all platforms? What is the impact of the bug?

The blockchain getting corrupted and the program crashing when you start it or when you send money are kind of annoying...
