Subject Re: Setting JIRA fix versions for 3.0.0 releases
Date Mon, 25 Jul 2016 21:14:05 GMT
Please don’t do this for 2.8.0 against 2.7.0 till we change our existing release ordering

Till now, I made sure 2.8.0 only has issues that are not in 2.7.3 - per the 2.8.0-follows-2.7.3
convention. As part of the release process, I will fix the remaining tickets to follow this
same convention. Again till we create new rules.
