See CHANGELOG.md for details.
Highlights: the retention rollups now serve the history they claim (coverage-aware read routing + the --backfill-rollups operator verb, ending the held-purge era with a one-time space reclaim); payload dedup hardened against concurrent-cycle deadlocks; compression cadence and memory floors set from field measurements; in-place PostgreSQL 17→18 store upgrades; Availability Group health across every edition; and the Full Dashboard + CLI Installer retire from release artifacts (deprecated, bug-fix support continues).
First release cut under the Lite + Darling process.
