 # Release
 
 Prepare a release PR for initium. This command handles version bumping, changelog updates, and PR creation. The release is published automatically when the PR merges (CI detects the version bump and creates the tag, which triggers the release workflow).

 ## [Unreleased]
 
+### Changed
+- Docker dependency cache now survives version-only bumps by normalizing the root package version in a preparatory build stage.
+
+## [1.3.0] - 2026-03-12
+
 ### Added
 - Auto-tag workflow: CI automatically creates a git tag when `Cargo.toml` version changes on main, triggering the release workflow.
 - `/release` skill for Claude Code: guided release preparation with version determination, confirmation, and PR creation.
 - `ignore_columns` option for reconcile mode tables: columns listed in `ignore_columns` are included in the initial INSERT but excluded from change detection, UPDATE statements, and content hash computation. Useful for timestamps, tokens, or values managed by database triggers.
 
+### Changed
+- Moved `/release` from Claude Code command to skill (directory-based `SKILL.md` format).
+
 ### Fixed
 - Replaced Dockerfile `--mount=type=cache` with dependency layer caching ("empty main" trick) for reliable Docker build caching in GitHub Actions, where `--mount=type=cache` does not persist across runners.
