We've released version 22.214.171.124. The release notes for version 3.4.1 (including changes for non-Android devices) can be found here.
As far as Android specific changes go, Bluetooth keyboards should work better and we've removed the COARSE_LOCATION permission that we previously used for statistical reporting. We've also updated the Scoreloop library to a version that allows you to opt-out of online high score tracking.
Please post in the forums or e-mail us (firstname.lastname@example.org) if you have any problems with the new version.
