Tencent and PUBG Corp. have rolled out a new update for the mobile version of PlayerUnknown's Battlegrounds. Update 0.3.3 is now available on both iOS and Android, although it's a fairly minor one in terms of the changes it brings to the game.

Along with some unspecified bug fixes, update 0.3.3 makes compatibility improvements on both platforms. On iOS, the update improves the game's performance on a range of already-supported devices, specifically iPhone 5s, iPad Air, iPad Mini 2, and iPad Mini 3. The Android version, meanwhile, adds support for more devices, although the patch notes don't specify which ones.
