Notes:
This is the second alpha release r777 (Milestone 3) of Z-Push 2.

This version contains visible feature for Android users as it supports HTML emails for these devices.
Further this version has several stability improvements (full AS status support) in the case of errors as well as many internal improvements.
The provisioning is fully functional, but still lacks of an user interface for e.g. the remote wipe.

The combined backend was improved in this version and offers some features which were not available in alpha1.

This version implements the same functionalities as Z-Push 1.5 (which was not the case in the alpha1). 
As many implementations where changed, we still require your feedback!

The states from Z-Push 1.x or the 2.0alpha1 versions are not compatible. You should remove these states when updating.
This version implements full automatic resynchronizing of the device when states are missing or faulty.

The default state directory is /var/lib/z-push, the default log directory /var/log/z-push.
Please create these directories and make them writeable for Apache or 
change the configuration parameters to fit your needs.

Be aware that if you are using LOGLEVEL_DEBUG and LOGLEVEL_WBXML Z-Push will be quite talkative, so it is advisable to use log-rotate on the log file.

Your feedback is highly appreciated!
