I can't tell you how many times I've looked up some feature or low-priority bug only to find the answer is "there's a PR for this that will be added in 10.9", commented like a year ago, glad to see the future plan is more frequent but smaller feature releases!
I'm glad for people who were waiting on this release. It took so long that I wrote my own media server in the mean time to resolve all the problems I was having with Jellyfin. I hope they can get more frequent releases out for folks still using it. Having looked at the code base, I understand that the cruft from Emby slows down development.
