This is a maintenance release that fixes deadlocks in expiration manager, SQL command timeouts in distributed locks (and in the DisableConcurrentExecution filter) and correctly handles poison messages in a schedule.

• Fixed – SQL command timeout in DisableConcurrentExecution filter.
• Fixed – SQL deadlocks in ExpirationManager background process.
• Fixed – Too many queries in SchedulePoller when background job is missing or in another state.

Please see the release notes on GitHub for linked issues. Thanks to Tom Kelly for helping with this release!
