After about 1.5 year of development, Inverse is extremely happy to announce the immediate availability of SOGo v3.0! This release is considered ready for production use.
SOGo v3.0 brings an unified device-agnostic Web interface aligned with Google Material Design guidelines. SOGo v3 shares virtually the same backend code as v2 so all the Enterprise ActiveSync features, DAV capabilities and native Outlook compatibility are present in v3 and they share the same maturity as v2. However, the new Web interface reaches new horizons:
Version 2 will continue to be maintained and it is possible to run both versions 2 and 3 concurrently on the same data set to ease the transition.
