We're very close to koji 1.12. We're targeting the middle of next week.
I'm using this PR to cover final release details: https://pagure.io/koji/pull-request/361
We're in a code freeze until then to focus on testing. I'm only taking critical bug fixes or doc changes related to the release.
If you're in a position to, now would be a great time to grab these bits and put them through their paces.
