In case you missed it, the official Mastodon Android app has been updated to include hashtag following and Mastodon's Lists feature! 🎉

The latest version of the app is v2.2.0.

Also, a reminder that you don't need to use the official app at all, you can get most features a lot sooner on third-party apps (e.g. Tusky, Fedilab, Megalodon, Subway Tooter etc).

Third-party apps for all platforms are listed on Mastodon's official site at https://joinmastodon.org/apps (scroll down past the official app).
