 # Changelog
 
+## 0.2.0.0 — 2026-07-30
+
+### Breaking Changes
+
+- Moved onto the Keiro 0.4 cohort through `kioku-core` and `kioku-migrations`. A database that was
+  migrated by kioku 0.1.0.0 picks up exactly two migrations on the next `kioku-migrate up` —
+  `keiro/0019-keiro-snapshots-state-shape-hash` and
+  `keiro/0020-keiro-workflow-children-failure-reason` — and reports every other migration as
+  already applied. Both add a column to a Keiro-owned table; no existing row is read or rewritten.
+  After the upgrade `kioku-migrate verify` reports `applied=38 pending=0 unknown=0`.
+
+### Deprecated
+
+- The `kioku-migrate import` subcommand, which imports a codd ledger into pg-migrate, is
+  deprecated. It remains fully supported for now. Removal is gated on the last codd-era downstream
+  database crossing over; see `kioku-migrations/codd-upgrade/README.md` for the gate and the full
+  list of what is removed together.
