Zentyal 3.1-2 Beta, a small Linux business server that can be configured as a Gateway, Unified Threat Manager (UTM), Infrastructure Manager, Office Server, Unified Communications Server or a combination of them, has been released and it's available for testing.
Zentyal 3.1-2 Beta is the final development version before the release of the 3.2 branch, which is expected to arrive sometime in September.
In the meantime, the current version has introduced a new “Users and Computers” interface based on a Tree view, support for multiple Organizational Units for some of the modules (Samba, Proxy, Mail, Zarafa), GPO support for login/logout scripts, and a few other improvements.
A complete list of changes and updates can be found in the official announcement. Download Zentyal 3.1-2 Beta right now from Softpedia.
Remember that this is a development version and it should NOT be installed on production machines. It is intended for testing purposes only.
