Fixes a bug from v2.2.6/v2.2.7: turning off a custom format group didn't stick — the group came back on after the next sync. v2.2.8 respects your choices again. What you tick or untick is exactly what gets synced.
Sorry for the rough 24 hours. v2.2.6 and v2.2.7 went out too quickly. Thanks for the reports and patience.
