0.2.2 (November 24, 2015)

• Bug fix: use INSERT IGNORE INTO instead of INSERT INTO to prevent SQL errors when two concurrent processes attempt to write failback flag at the same time.
• Bug fix: use E_USER_WARNING with trigger_error().

• Show an admin notice when Redis is unavailable but is expected to be.

0.1
