Need to expose 2.3.x branch so that PR's can be provided

[ssotangkur-kahuna]

I needed to use v.2.3.0 since it is still backwards compatible w/ React 15.x, however I also needed to bundle the dependencies together into a UMD bundle. I'm able to provide a PR for changes off of the v2.3.0 tag, on my fork, however I cannot provide a PR back to this repo since there's no 2.3.x branch for git to compare to.

You can create a branch and publish it to github using the following commands from your repo:

git checkout v2.3.0
git checkout -b v2.3.x
git push -u origin v2.3.x

Done. Thanks for the detailed explanation.

LMK if you need any help merging new features or bugfixes from v.3
