Differnce in between Android 4.2.2 and 4.2.1 Just updated my HTC One X from cm-10.1-20130119 to cm-10.1-20130304-EXPERIMENTAL.

The only difference I noticed is my android is now on 4.2.2 from 4.2.1.

Can anyone list me difference in between them ?
As far as Android is concerned, 4.2.1 to 4.2.2 contained only a few things. They include:


Show remaining time for downloads from the Play Store
Provide a system notification sound when wireless charging begins
Allows long-pressing on certain tiles in Quick Settings


In reality, since you have a device that doesn't support wireless charging, the second point obviously doesn't apply to you. And since CM already heavily modified the tiles for Quick Settings and offers far more options that this update introduced, the only benefit you would get out of this update would be showing the remaining time.

But, CM has new features being added all the time that are separate of the features added by Google. If you look under Settings -> About Phone -> View Changelog, you can see a big list of all the major features that CM 10.1 adds to Google's Android 4.2.2 release.

And if you want to look at all the specific changes (usually around 10-50 per day, although, some are new features, some are bug fixes for devices not related to yours, and some are new/updated translations), you can see it online at http://changelog.bbqdroid.org and clicking on your device and CM version. You can browse through the changes for each nightly there, and although some of the subjects can be cryptic, you can still usually make out what new features are being introduced.
