I've created 1.9.x branch and we're ready to start testing.
Same procedure as last time. Open
https://docs.google.com/spreadsheets/d/1nHHhuXMZJJpV40gXwQWKyyTnAULMv3S4a...
and add your 'Result' column in the name of the test you're going to do.
Once completed change the value to 'PASSED' or 'FAILED'. If failed create
JIRA's and link in comments section.
Remember for fixes send PR to both master and 1.9.x branch.
