Semantic MediaWiki 1.4.2 released: Better performance, PostgreSQL support, JSON export
Feb 11 2009. With Semantic MediaWiki 1.4.2, the Help:SMW Project provides the second update for SMW 1.4. The new version includes a number of changes such as significant performance improvements, initial PostgreSQL support, and a new JSON data export. Also, the query formats vCard and iCalendar have been moved to Extension "Semantic Result Formats" 1.4.2, so it is wise to update both extensions at the same time. Other than this, upgrade is very easy, see Installation 1.4.2 for details. Further information is found on the SMW 1.4.2 page.
