Build 44 Looks good. The swipe up for caps is working again. The swipe down and hold brings up the menu and nothing else. Personally I like the two finger swipe up better. The keyboard is stable and responsive.
I still do not hear anything when deleting partial words. I may be in the minority, but I would rather hear gibberish then nothing, at least I would have an idea where the cursor is. Otherwise, I like it!
