Release Notes: A lot of small improvements were made across all modules and also to Microsoft ActiveSync support, so you can sync with any phone that supports ActiveSync. The link browser and management of newsletters were improved a lot. The new advanced search in the addressbook lets you select any dataset from the addressbook and save that search.
Release Notes: Performance was improved. Compression is used on the files, so the startup time of Group-Office is much faster. Enhancements were made to the permissions system to deliver much better overall performance on large installations. New features include resource management, an enhanced project manager, a module for tickets or helpdesk functionality, and a lot of small enhancements everywhere in the system. Upgrading is recommended.
