Hopefully it won’t update to 0.18 at all. 0.18 doesn’t support captchas for sign ups.
0.18.1 will add them back though
Only 0.0.35 will work with 0.18 due to some breaking changes. It should be available on Google Play now.
Still beta, and it still has lots of bugs to work out. Like mods can't fully remove posts, accounts can't be deleted, 2FA is not done, and other small stuff.
