Thank you everyone for your contributions!

This is a breaking release removing some annoyances, specifically the toSingle() and toMaybe() extension functions targeting futures, callables, and even single T items.

These caused far more harm than good, as they often clashed with other libraries and people's own extensions. For instance, RxKotlinFX has a Dialog<T>.toMaybe() extension which emits a dialog's response. This clashed directly with the toMaybe() in RxKotlin. Rather than deprecating these extensions, they were just removed to prevent further hindrance.

Deprecated Observable#combineLatest() and its Flowable counterpart have been removed as well, and you can use the Observables and Flowables factories instead.

RxJava and Kotlin dependencies have been updated as well.

There are a number of changes in this release, some of which are possibly breaking. Many additions seek to expand the SAM helpers used to workaround the SAM issue.

• zip(), combineLatest(), zipWith(), and withLatestFrom() now support emitting Pairs and Triples when no combining function is provided for 2-3 source arguments. This applies to Observable, Flowable, Single, and Maybe types.

• Singles and Maybes have been greatly expanded to include more SAM helper operators for zip() and zipWith()

• toMap() and toMultimap() extension operators have been added to Observable<Pair<X,Y>> and Flowable<Pair<X,Y>>, which will automatically use each Pair emission to map the key and value without any arguments.

• Order of parameters for subscribeBy() have been moved so that onNext is the default if only one unnamed parameter is provided.

• Kotlin 1.2 and RxJava 2.1.0 are now dependencies

Please file any issues if you have any questions or concerns. Thanks to everyone who contributed to this release.

This is a quick release to remove Java 8 configuration, so this works on Java 6+.

Also a blockingSubscribeBy() has been added as discussed here.

This is a re-release of the features in 2.0.1 to address some build issues during deployment. combineLatest() also received extensions to work with Pair and Triple emissions.

Thanks @stepango for putting these changes in.
