This is a bug fix release which has some critical fixes, especially for CalendarIntevalTrigger future date calculation and trigger's next fires not being processed in a timely fashion when AdoJobStore is used with DisallowConcurrentExecutionAttribute and trigger has short repeat interval.

This update is highly recommended for all users.


  • StdAdoConstants.SqlSelectSchedulerStates does not filter on the SCHED_NAME column
  • CalendarIntervalTrigger produces incorrect schedule
  • Trigger completion signaling from AdoJobStore does not work properly when DisallowConcurrentExecution is set


  • IDisposable jobs should be disposed after execution
  • Support for defining DbMetadata via App.config's quartz section
See download and installation instructions.
