My Constraint Programming Blog: Global Constraint Catalog, update

I have completely missed to blog about the update of the great online Global Constraint Catalog. It was done 2009-04-03 and had the following changes:

gccat_systems.xml: references to global constraints implemented within the constraint systems Choco and Gecode. (For now, the references appear in this XML file only; they will soon be integrated within the catalog.)
gccat_schema.xml: the XML Schema of the catalog schema.xsd with a stylesheet
navigation bar (prev/next) added
google tools added: search and analytics

I really like the comparison of the constraint names in Choco and Gecode, it's very helpful. Maybe other systems will be added later, say JaCoP, MiniZinc and Comet?
