Ask HN: What should I verify before releasing a P2P messenger?

I’m releasing 1.0 of an open-source desktop P2P messenger tomorrow - Realman78/Kiyeovo on GitHub. In short, it's a feature rich messenger with clearnet “Fast mode” and an optional Tor-routed “Anonymous mode.” Before the "release" tomorrow, I want to catch anything I might have missed.

For people who have shipped tools from this domain (privacy/messaging/security): what would you verify now that you have less than 24 hours?
