What's New in This Release: [ read full changelog ]

New features:
· The "health-check" functionality is now capable of fixing damaged document-sets of collections.
· The sync_commit configuration property is now set by default.

Bug fixes:
· A defect in Collection cache could occasionally lead to invalid document-set properties of collections.
· fixed a memory management issue: a cache used for database storage read-access should have been shared but was not, resulting in an excessive memory consumption. This was a problem only when managing a large number of XML Libraries (100 or more).
