Extensibility • Added – `Factory`, `StateMachine` and `Performer` properties to context classes to avoid injecting services. • Added – Allow to pass custom data to `ApplyStateContext` and `ElectStateContext` instances. • Added – Preserve custom data dictionary between the entire filter chain. • Added – Allow to pass transaction to background job state changer when new methods implemented. • Changed – Ignore some members when serializing a `JobFilterAttribute` instance to decrease payload size. Storage • Added – Virtual `JobStorage.GetReadOnlyConnection` method intended to return `JobStorageConnection` for replicas. • Added – Virtual `JobStorage.HasFeature` method for querying optional features. • Added – Optional `GetSetCount` and `GetUtcDateTime` methods for the `JobStorageConnection` class. • Added – Optional `AcquireDistributedLock` and `RemoveFromQueue` methods for the `JobStorageTransaction` class. • Added – Support for transactional acknowledge using new storage method for better handling some data loss scenarios. • Added – `CreateJob` method to the `JobStorageTransaction` abstract class. • Added – `SetJobParameter` method to the `JobStorageTransaction` abstract class. • Added – Experimental `JobStorageConnection.SetContains` method. • Added – Optional `ParametersSnapshot` property for `BackgroundJob` and `JobData` classes to minimize roundtrips in future. • Added – Fetch "Retries" metric with other statistics when supported by storage. • Added – `JobStorageMonitor` class with more available methods for the new features. • Changed – Allow to query job parameters without additional roundtrip when supported by a storage. • Changed – Expose state data dictionaries in list DTOs when supported by storage.
