1.7.0 • Added – Full .NET Core 2.0 support by explicitly targeting .NET Standard 2.0. • Added – IGlobalConfiguration.SetDataCompatibilityLevel to enable rolling upgrades from version 1.6. • Added – IGlobalConfiguration.UseRecommendedSerializerSettings method for new installations. • Added – Assemblies now loaded automatically when resolving a type when using default type resolver. • Added – Custom TaskScheduler can now be specified in BackgroundJobServerOptions for workers. • Added – IdempotentCompletionAttribute filter to enforce strict order for continuations. • Added – IBackgroundJobClient.ContinueJobWith methods to replace ContinueWith ones in future for clarity. • Added – JobStorage.LinearizableReads virtual property to avoid unnecessary waits in state changer. • Added – Allow async methods to run their continuations on worker thread by disabling TaskScheduler. • Added – Multi-stage shutdown to wait for graceful completion before starting to abort jobs. • Added – Asynchronous checks for job cancellation, IJobCancellationToken can be replaced with CancellationToken (by @pieceofsummer). • Added – Possibility to create millions of recurring jobs without stressing the scheduler. • Added – Second-based recurring jobs are fully supported now with 6-part cron expressions. • Added – Support for custom TimeZoneInfo resolvers in recurring jobs for interoperability purposes. • Added – Package now explicitly targets .NET Standard 2.0, and .NET Framework 4.6 target added as well. • Added – Type roundtrip support between .NET Core and .NET Framework for most common types. • Added – Allow to specify queue names based on job arguments with QueueAttribute via patterns. • Added – PerformContext.Storage property to allow server filters to spawn connections. • Added – GetFirstByLowestScoreFromSet connection method overload that returns multiple items (by @cdschneider). • Added – Entry point for custom job naming strategies available for dashboard (by @pieceofsummer). • Added – JobDisplayNameAttribute class for displaying jobs in dashboard, available on .NET Core (by @pieceofsummer). • Added – Support for async jobs returning ValueTask (by @pieceofsummer). • Added – Support for asynchronous background processes, opens the road toward async storage. • Added – Circuit breaker pattern for background processes to reduce the logging pressure. • Added – Processing server is now able to detect it was expired, and restart itself with the new id. • Added – Ability to use custom delays for automatic retries of a background job. • Added – ThreadAbortException and ThreadInterruptedException handling to keep the background process running. • Added – Support for complex Cron expressions, including the L, W, # characters. • Added – JobActivator.BeginScope method overload with the full PerformContext (by @jeroenvervaeke). • Added – Support for read-only view for dashboard (by @mikechamberlain). • Added – Storage property to control the job expiration time (by @rsilvanet). • Added – Decrease the size of serialized type payloads and remove version information. • Changed – Make TaskScheduler.Default the default scheduler for async jobs to avoid breaking changes. • Changed – Split serializer setting to Internal and User scopes to isolate them (Version_170 Switch). • Changed – Don't allow to affect internal serialization even by JsonConvert.DefaultSettings (Version_170 Switch). • Changed – Share the same type binder between Hangfire itself and Newtonsoft.Json (Version_170 Switch). • Changed – Use more compact representation of dates when using SerializeDateTime (Version_170 Switch). • Changed – Stop using special case for DateTime argument serialization (Version_170 Switch). • Changed – Don't serialize unused AwaitingState.Expiration field (Version_170 Switch). • Changed – Specify parameter type when serializing arguments to allow using TypeNameHandling.Auto option. • Changed – Use case sensitive search when resolving a type as by default in .NET. • Changed – Make SucceededState constructor public to allow state serialization. • Changed – Add IBackgroundJobFactory.StateMachine property (breaking change for low level API). • Changed – Replace Rickshaw with Chart.js to have beautiful charts with less headache. • Changed – DelayedJobScheduler is able to use the new storage method to query multiple jobs at once. • Changed – RecurringJobScheduler now uses index-based checks to fetch only those jobs that should be scheduled. • Fixed – Worker now logs an error, when all the state change attempts failed due to an exception. • Fixed – Don't serialize arguments multiple times when showing job details in dashboard. • Fixed – DateTimeOffset conversion error when it was serialized with TypeConverter. • Fixed – Remove duplicate of argument deserialization code for obsolete Job class methods. • Fixed – Decorate all the exceptions with the SerializableAttribute. • Fixed – ArgumentNullException when job class contains method with non-resolvable generic arguments. • Fixed – "Failed to initialize CoreCLR" error, by removing reference to Microsoft.NETCore.Portable.Compatibility. • Fixed – Possible race conditions in RecurringJobScheduler that may lead to job duplicates. • Fixed – Configuration inconsistency introduced in 1.6.18 leading to issues with custom JobActivator. • Fixed – Triggering the recurring task doesn't update its last execution time. • Fixed – Recurring job which don't have next execution (intentionally or not) don't cause exception. • Fixed – Dashboard recurring jobs sorting is random (now it's based on next execution time). • Fixed – Performance problems with huge amount of recurring jobs. • Fixed – NextExecution field of a recurring job has delay in value getting set. • Fixed – Dashboard graphs have improper sizing. • Fixed – Server disappears from the list, but still performing the background processing. • Fixed – Logging is too aggressive on transient errors. • Fixed – Daylight saving time transitions now handled perfectly in recurring jobs thanks to Cronos. • Fixed – Confusing Cron scheduling, when both day-of-week and day-of-month fields set. • Project – Add DataCompatibilityRangeFact and DataCompatibilityRangeTheory classes for compatibility checks. • Project – Reduce test execution time by removing unnecessary waits.
