Summary

Version 2.2.0 is the next minor release of the 2.x era and contains the standardization of many experimental API additions from the past year since version 2.1.0. Therefore, the following components are now considered stable and will be supported throughout the rest of the life of RxJava 2.x.

Classes, Enums, Annotations

  • Annotation: N/A
  • Subject: MulticastProcessor
  • Classes: ParallelFlowable, UndeliverableException, OnErrorNotImplementedException
  • Enum: ParallelFailureHandling
  • Interfaces: {Completable|Single|Maybe|Observable|Flowable|Parallel}Emitter, {Completable|Single|Maybe|Observable|Flowable|Parallel}Converter, LambdaConsumerIntrospection, ScheduledRunnableIntrospection

Operators

  • Flowable: as, concatMap{Single|Maybe|Completable}, limit, parallel, switchMap{Single|Maybe|Completable}, throttleLatest
  • Observable: as, concatMap{Single|Maybe|Completable}, switchMap{Single|Maybe|Completable}, throttleLatest
  • Single: as, mergeDelayError, onTerminateDetach, unsubscribeOn
  • Maybe: as, mergeDelayError, switchIfEmpty
  • Completable: as, fromMaybe, onTerminateDetach, takeUntil
  • ParallelFlowable: as, map|filter|doOnNext(errorHandling)˙, sequentialDelayError
  • Connectable{Flowable, Observable}: refCount(count + timeout)
  • Subject/FlowableProcessor: offer, cleanupBuffer, create(..., delayError)
  • Test{Observer, Subscriber}: assertValueAt, assertValuesOnly, assertValueSetOnly

(For the complete list and details on the promotions, see PR 6105.)

Release 2.2.0 is functionally identical to 2.1.17. Also to clarify, just like with previous minor version increments with RxJava, there won't be any further development or updates on the version 2.1.x (patch) level.

Other promotions

All Experimental/Beta APIs introduced up to version 2.1.17 are now standard with 2.2.
