2.4.2.2

The OBM team is proud to announce the availability of OBM version 2.4.2.2.

Following is a summary of what changed:

## OPush

This version fixes two crucial bugs :

1. Since 2.4.2.0, we store more sensitive information into EHCache and expect it to be persistent. Unfortunately, it doesn't work as expected for various reasons and every server restart makes this information disappear. It's now fixed into 2.4.2.2.
2. Some phones had a hard time doing initial synchronization, so we are now more forgiving about protocol respect to make it work smoothly.
