Gateware v2.2 is now released.

It fixes a bug whereby a pulse was generated on startup when the board is in TTL-BAR repetition mode and with the glitch filter on. The bug was due to an issue in the first pulse inhibit logic inside the pulse generator block. This logic was de-activating one clock cycle early as compared to the trigger logic when the glitch filter is on, thus resulting in a pulse still being generated on startup.
