New blog post: https://jellyfin.org/posts/testing-10.9.0

This is our official announcement of the 10.9.0 feature freeze, as well as an overview of the upcoming release plan and instructions on how to help test it and report bugs! The more people we get testing early, the more bugs we can find and squash before the planned release in ~1 month! Happy watching!
