2009. The first public version of the DRI2 protocol (2.0) was announced in April 2009. Since then there has been several revisions, being the most recent the version 2.8 from July 2012. Due to several limitations of DRI2, a new extension called DRI-Next was proposed by Keith Packard and Emma Anholt at the X.Org Developer's Conference 2012. The extension was proposed again as DRI3000 at Linux.conf.au 2013. DRI3 and Present extensions were developed during 2013 and merged into the X.Org Server 1.15 release from December 2013. The first and only version of the DRI3 protocol (1.0) was released in November 2013.
