+- **BREAKING:** Increased the minimum Node.js version to 22.22.1 (required by `lint-staged`).
 - **BREAKING:** Restricted package exports so Optimizt is only exposed as a CLI package.
+- Pinned the Docker base image to `node:22.22.1-alpine3.23` for reproducible builds.
+- Replaced `simple-git-hooks` with versioned hooks in `.githooks`; contributors working on Optimizt code can run `npm run enable-git-hooks` after cloning to configure `core.hooksPath`.
+- Updated dependencies no longer ship `postinstall` scripts, following the ecosystem move away from dependency lifecycle scripts in npm and other package managers (see [npm RFC #868](https://github.com/npm/rfcs/pull/868)).

 # Migration
 
+## 12.1.1 → 13.0.0
+
+Node.js version must be 22.22.1 or higher.
+
+Optimizt is now exposed only as a CLI package. If you imported Optimizt internals from JavaScript, switch to the `optimizt` CLI instead.
+
+Git hooks are no longer configured through `simple-git-hooks`. This affects only contributors working on Optimizt code, not users installing Optimizt as a package. After cloning the repository, contributors can run:
+
+```shell
+npm run enable-git-hooks
+```
+
+This configures Git to use versioned hooks from the `.githooks` directory through `core.hooksPath`.
+
 ## 11.0.0 → 12.0.0
 
 The SVGO configuration has been updated to be compatible with SVGO v4 (see [migration guide](https://svgo.dev/docs/migrations/migration-from-v3-to-v4/)). If you use a custom [.optimiztrc.cjs](.optimiztrc.cjs) file, update your SVG plugins configuration to match the new format.
