Excellent, thank you for all of the fixes and continued work on booleans!
A grammatical nitpick on booleans (from 2.2.1, still in 2.2.2): the description under Difference: "subtract objects from secondary selection" is backwards to the actual behavior. It should be more like "subtract secondary selection from objects."
