The latest MEAP (last update: 2017-11-01) still focuses on RxJava 1.x [page 12], not covering RxJava 2.
Is that going to be the case although Android specific bindings for RxJava 2 already exist?

I don't think it should have a substantial effect.

According to https://github.com/ReactiveX/RxJava/wiki/What's-different-in-2.0, there's quite a bunch of differences.

Do you have a specific use case in mind?

Honestly, when/if this book hits the bookstores some day, I wouldn't buy it unless it uses the latest stable version of RxJava, which more likely is RxJava 2.x than 1.x based.

I would say the differences between RxJava 1 & 2 are subtle and probably will not come up in the book. I'll try to update if I notice anything substantial.

So far, Ch 1- 3 do not distinguish between RxJava 1 or 2
For RxBinding use https://github.com/JakeWharton/RxBinding
Don't use the Jack compiler, it is deprecated. Android Studio 3.0 supports Java 8 Lambdas (not Streams)

Ch 4 Difference, subscriptions

RxJava 1.x has

RxJava 2.x has

Another difference is that in RxJava 1 it seems like you could add an unsubscribe callback to a subscription. In RxJava 2 see the source code for the RxJava binding to get an idea how this can be done
