• Pull 6827: Fix Flowable.flatMap not canceling the inner sources on outer error.

3.0.0-RC7

Maven
Javadocs

⚠️ With this release, RxJava moved to a Java 8 baseline. This means the library is now built with -target 8 settings to produce Java 8 bytecode and requires a Java runtime >= 8 to work. Most desktop and server-side usages should be fine.

For Android development, the latest Android Studio is always recommended which is already able to desugar many Java 8 constructs. The upcoming AS 4 will support even more desugaring for older API levels. Until then, one should stick to the non-Java 8 standard methods so the Java 8 methods can be ignored by AS.

This is an early release for 3.0.0 to allow preparations for the breaking API changes and cleanups. Please check out the wiki page What's different in 3.0 from time to time for the details and migration guide.
