     •ɾCompatibility with Xcode 10.0 •ɾAdds new insert extension to collect and add multiple disposables to DisposeBag. •ɾAdds scan(into:accumulator:). •ɾAdds queuePriority parameter (defaults to .normal) to OperationQueueScheduler. •ɾPerformance enhancement reduces Bag dispatch inline code size by 12%. •ɾAdds customCaptureSubscriptionCallstack hook to allow custom subscription callstacks to be generated. •ɾRemove usage of Variable from Playground, Example projects and Tests. •ɾAdd XCTAssertRecordedElements to XCTest+Rx.

     •This relase introduces new framework RxAtomic that enables using C11 atomic primities •in RxSwift as a replacement for deprecated OSAtomic* functions.
 Carthage users will probably need to include this framework manually. •ɾUpdates deprecated OSAtomic* primitives to use C11 atomic primitives. •ɾAdds Event, SingleEvent, MaybeEvent and Recorded conditional conformance •ɹto Equatablewhere their Element is equatable on RXTest for clients that are using Swift >= 4.1. •ɾAdds string to NSTextView. •ɾConsolidates per platform frameworks to multi-platform frameworks. •ɾXcode 10.1 compatible. •
