0.20 Release Candidates

[benjchristensen]

Since the backpressure (#1000) changes are non-trivial I suggest we do 0.20.0-RC* releases until it stabilizes, similar to how we did 0.17.

I propose branching master into 0.19.x for ongoing maintenance releases and allowing master to be used for active development of 0.20 and the backpressure changes.

Any issues with me proceeding with this approach? I'd like to do this no later than Monday if there are no issues with this approach.

Makes sense.This will give us a change to shake out bug and perf issues and for people to code their favorite examples that require back pressure to kick the tires of the API.

Very much appreciated. I'll ship the couchbase sdk developer preview 2 with 0.19 and hopefully move the upcoming beta to 0.20! Looking forward to test it.

I have merged the code into master ... I intend on releasing within the next 12-36 hours after some further validations and tweaks.

I have not released anything because there is a critical bug blocking me: #1420

[benjchristensen]

It looks like I may have solved #1420 so can do a preview release. The only thing that isn't done that I want done is the zip operator. I have it almost done. Should I release the preview before I finish zip, or wait until I finish that?

I'd go ahead so we can all play with it and hopefully find no other bugs.

I have released 0.20.0-RC1: https://github.com/Netflix/RxJava/releases/tag/0.20.0-RC1
