Welcome to the excessively-large December 2025 Edge Release Roundup posts, where we dive into the most recent edge releases to help keep everyone up to date on the latest and greatest! This post covers edge releases from September through November 2025 (the runup to KubeCon was hectic around here).
How to give feedback
Edge releases are a snapshot of our current development work on main; by
definition, they always have the most recent features but they may have
incomplete features, features that end up getting rolled back later, or (like
all software) even bugs. That said, edge releases are intended for
production use, and go through a rigorous set of automated and manual tests
before being released. Once released, we also document whether the release is
recommended for broad use – and when needed, we go back and update the
recommendations.
