Version **2.5.3** is now available for free download and free upgrade. It replaces version 2.5.2 or any older major version.
# What's new in this release ?
## Improvements
* [PHPCas](https://wiki.jasig.org/display/CASC/phpCAS) has been upgraded to the latest version which is 1.3.2
* obm-autoconf is now packaged for Red Hat and CentOS
##### Smartphone synchronization via Opush
* Opush now manages its in-memory datastore based on object size to prevent overloading JVM memory. It allows a strict split of the memory between data and query processing. See [ehcache](http://www.obm.org/content/opush-ehcache) for more details
* As an added bonus, we made everything configurable because users have different needs and administrators can monitor the datastore behaviour with their beloved [CRaSH](http://www.obm.org/content/crash) shell
* Finally, be aware that this version will process a live migration when starting, as described [here](http://www.obm.org/wiki/migration)
## Bug fixed
##### Web based user interface
* A contact where the company name contains a single quote is now correctly saved and not truncated
* Contact company with a single quote is retrieved in an auto completion process
* Very long first or last contact names are saved without errors
* A resource can be added in a private group
* The list of mobile devices doesn't retrieve devices of all domains anymore
* List of custom calendar views has been improved: no more brackets, better refresh of the list
