The main novelty of the current release is the ACIDE bundle which includes a new version 0.12 featuring a PDG panel for displaying the predicate dependency graph, and also relocatable panels to reorganize the IDE layout. With respect to DES itself, some enhancements have been added, related to an extension to RA projection and Datalog division. Also, more information has been added for unsafe rules (mode information and set variable unsafety) and SQL syntax errors. Changes include overriding the current answer ordering when an order by metapredicate or clause is involved in the query, and duplicate elimination, which works closely to SQL implementations when involving null values. The complete list of enhancements, changes and fixed bugs are listed in the Release Notes and in Section 11.1 of the User Manual.
