This bug fix release contains an important fix to anyone configuring jobs using job builder's DisallowConcurrentExecution() without having the attribute DisallowConcurrentExecutionAttribute on type itself.

FIXES

  • Add missing "disallow concurrency" materialization for jobs (#1923)
  • Allow accessing the wrapped scoped job instance from job execution context (#1917)
  • JobDiagnosticsWriter can throw error when writing context data (#1191)
See download and installation instructions.
