10. in RxJava 2.0 RC-2
12. https://github.com/ReactiveX/RxJava/wiki/What's-different-in-2.0#nulls
14. Package Renaming
15. in RxJava 1.x
16. rx

22. Subscription Renaming
23. in RxJava 1.x
24. Subscription CompositeSubscription SerialSubscription MultipleAssignmentSubscription
25. in RxJava 2.0 RC-2
26. Disposable CompositeDisposable SerialDisposable https://github.com/ReactiveX/RxJava/wiki/What's-different-in-2.0#subscription
27. CompositeSubscription → CompositeDisposable https://github.com/ReactiveX/RxJava/wiki/What's-different-in-2.0#subscription Subscription → Disposable SerialSubscription MultipleAssignmentSubscription → SerialDisposable
31. Functional Interfaces Renaming

43. Observable Separation
44. in RxJava 1.x
45. Observable ↓ Non-Backpressured Backpressure-Enabled
46. Backpressure? In RxJava it is not difficult to get into a situation in which an Observable is emitting items more rapidly than an operator or subscriber can consume them. This presents the problem of what to do with such a growing backlog of unconsumed items. https://github.com/ReactiveX/RxJava/wiki/Backpressure#introduction
47. in RxJava 2.0 RC-2
48. ↓ Observable Non-Backpressured https://github.com/ReactiveX/RxJava/wiki/What's-different-in-2.0#observable-and-flowable
49. ↓ Flowable Backpressure-Enabled https://github.com/ReactiveX/RxJava/wiki/What's-different-in-2.0#observable-and-flowable
