The Inverse Team is pleased to announce the immediate availability of SOGo 1.3.15. This is a minor release of SOGo which focuses on improved stability over previous versions.

=== What is SOGo ===

SOGo is a free and modern scalable groupware server. It offers shared calendars, address books and emails through your favorite Web browser or by using a native client such as Mozilla Thunderbird and Lightning.

SOGo is standard-compliant and supports CalDAV, CardDAV, GroupDAV and reuses existing IMAP, SMTP and database servers - making the solution easy to deploy and interoperable with many applications.

SOGo features :

* Scalable architecture suitable for deployments from dozen to many thousand users * Rich Web-based interface that shares the look and feel, the features and the data of Mozilla Thunderbird and Lightning * Improved integration with Mozilla Thunderbird and Lightning by using the SOGo Connector and the SOGo Integrator * Two-way synchronization support with any SyncML-capable devices (BlackBerry, Palm, Windows CE, etc.) by using the Funambol SOGo Connector * Excellent integration with Apple iCal, Apple iOS and Android-based devices

and many more! SOGo and our connectors are completely free.
