0.18.0

This release takes us a step closer to 1.0 by completing some of the remaining work on the roadmap.

Scheduler

The first is simplifying the Scheduler API.

The Scheduler API is now simplified to this:

class Scheduler {
    public abstract Worker createWorker(); 
    public int parallelism();
    public long now();

    public abstract static class Worker implements Subscription {
        public abstract Subscription schedule(Action0 action, long delayTime, TimeUnit unit);
        public abstract Subscription schedule(Action0 action);
        public Subscription schedulePeriodically(Action0 action, long initialDelay, long period, TimeUnit unit);
        public long now();
    }
}

This is a breaking change if you have a custom Scheduler implementation or use a Scheduler directly. If you only ever pass in a Scheduler via the Schedulers factory methods, this change does not affect you.

Additionally, the ExecutionScheduler was removed because a general threadpool does not meet the requirements of sequential execution for an Observable. It was replaced with rx.schedulers.EventLoopScheduler which is the new default for Schedulers.computation(). It is a pool of event loops.

rx.joins

The rx.joins package and associated when, and and then operators were moved out of rxjava-core into a new module rxjava-joins. This is done as the rx.joins API was not yet matured and is not going to happen before 1.0. It was determined low priority and not worth blocking a 1.0 release. If the API matures inside the separate module to the point where it makes sense to bring it back into the core it can be done in the 1.x series.

Deprecation Cleanup

This releases removes many of the classes and methods that have been deprecated in previous releases. Most of the removed functionality was migrated in previous releases to contrib modules such as rxjava-math, rxjava-async and rxjava-computation-expressions.

A handful of deprecated items still remain but can not yet be removed until all internal operators are finished migrating to using the lift/Subscriber design changes done in 0.17.0.
