Jenkins User ConferenceSan Francisco, Sept 30 2012 #jenkinsconfJoin Plugin: provides concurrency join operation (last release v1.15 3-May-2012)Locks and Latches: another plugin to control parallel execution (last release v0.6 16-Apr-2010)Drools: similar to Jenkow in using graphical editor in EclipseBuild Flow: define workflow in DSL (last release v0.5 3-Sep-2012)
