Please tell me this is for the version 4 branch, not 3?
It does only affect the 4.x branch. 3.x is deprecated, however, and you should make a plan to move forward to a 4.x version, and Elasticsearch 2.x to go with it.
Phew...thank you Aaron. And until Color palette selection is addressed, there's no way in the world I'm upgrading. Thanks again
