+
+## [0.3.0] - 2026-04-24
+
+### Added
+
+- **Official `workflow-migrate` Docker image published to GHCR** — each release now builds and pushes `ghcr.io/gocodealone/workflow-migrate:{version}` (multi-arch: linux/amd64 + linux/arm64). Pre-release tags (containing `-`) are versioned only; stable releases also push `:latest`. Image uses the existing distroless/static base with a non-root user and no shell. BMW and other consumers can reference the image directly without cloning and building from source.
+
+## [0.2.0] - 2026-04-15
+
+### Added
+
+- Atlas driver (`workflow-plugin-atlas-migrate`) for schema-as-code migrations
+- `workflow-atlas-migrate` lint tool standalone binary
+- Atlas plugin binary and release artifacts
+- `cmd/workflow-migrate/Dockerfile` for building standalone migration runner image
+
+## [0.1.0] - 2026-04-01
+
+### Added
+
+- Initial release: `workflow-plugin-migrations` plugin binary
+- golang-migrate and goose drivers
+- Module types and pipeline steps
+- Conformance test suite
+- `workflow-migrate` standalone binary for pre-deploy jobs
