Phaser 2.4.2, version "Altara" was released today. This is a small point release that contains a number of important Pointer and Input related fixes, specifically on Linux and Cordova platforms.
If you were experiencing any problems with touch or button events not working in Phaser 2.4 (or 2.4.1) then please upgrade to 2.4.2 immediately. There are no API changes in this release, so it's a safe replacement.
