Per the release schedule, I plan to cut release candidate 0 (RC0) of Traffic Control 1.6 on 6/30. Consider this your 2 week warning. Any Github issues you anticipate delivering with 1.6, please tag them with the 1.6 milestone so we have a good idea of the scope of the release.
Keep in mind that once RC0 is cut and a 1.6.x branch is created, all pull requests to the 1.6.x branch should be limited to regressions.
Also, if you have open pull requests, you may want to consider pinging your reviewer to ensure they are merged in time for the release.
Thanks.
