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/1nHHhuXMZJJpV40gXwQWKyyTnAULMv3S4a5WqljrWr7c 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.
