• 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.
