About The Lounge
The Lounge ships steadily but publishes release notes that say nothing.
The Lounge is moving through a normal maintenance cadence — a 4.5.0 that took three release candidates, two 4.5.1 pre-releases, a 4.5.2 to repair Docker and Linux packaging, and now a 4.6.0 pre-release. What none of these entries contain is content. Every announcement is the project's standard pre-release boilerplate pointing at a commit list, so the changelog documents that work happened without saying what it was.
