Today we released version 

Preparing the projectdoc Toolbox worked for all integration aspects almost out-of-the-box. The main challenge was to cope with the increased performance requirements under heavy load. Another important amount of work was required to establish the test environment to cope with Atlassians requirements to accept the projectdoc Toolbox for data center on their Marketplace.

Well, finally, it's done! 

Since this is a major release expect many breaking changes. One of the most relevant for your upgrade is the new database structure the projectdoc Toolbox establishes. Since the projectdoc tables did not store any information that cannot derived from the Confluence pages, you simply need to rebuild the table data from scratch. Unfortunately this requires, especially for large installation quite a lot of time. We recommend to check the upgrade process in a test environment on real data.
