# v0.105.2 full implementation details

**Status: Released (2026-09-11).** v0.105.2 validates the supported
PostgreSQL 18 packages and frozen v0.105 contracts with active-data upgrades,
operational checks, and release benchmark smoke tests.

## Completed work

- ✅ Done — package metadata, Docker defaults, archives, and the
  v0.105.1 → v0.105.2 upgrade path are version-synchronized.
- ✅ Done — the packaged candidate runs Graph V1, Delta V1, DVM, recovery,
  WAL, snapshot, diagnostics, and upgrade qualification.
- ✅ Done — quick Criterion benchmark smoke runs before release publication.
- ✅ Done — release evidence records the candidate commit, supported artifact
  metadata, checksums, PostgreSQL version, suite results, and retained logs.
- ✅ Done — documented release, upgrade, rollback, and operator procedures are
  checked as part of the release gate.

## Deliberately deferred

The 72-hour mixed-workload soak, seven-day longevity environment, release
candidates, and v1.0 release remain deferred to later qualification work.
