 ## Versioning

 Starting from `v8`, all historical metadata type definitions are retained. These can be enabled via features e.g. `v13`. The latest version is enabled by default. All legacy versions are available under the `legacy` feature.

+# Release Checklist
+
+These steps assume that you've checked out the `frame-metadata` repository and are in the root directory of it.
+
+We also assume that ongoing work done is being merged directly to the `main` branch.
+
+1. Ensure that everything you'd like to see released is on the `main` branch.
+
+2. Create a release branch off `main`, for example `release-v14.3.0`. Decide how far the version needs to be bumped based
+ on the changes to date. If unsure what to bump the version to (e.g. is it a major, minor or patch release), check with the
+ Parity Tools team.
+
+3. Check that you're happy with the current documentation.
+
+ ```bash
+ cargo doc --open --all-features
+ ```
+
+ Optionally you can also confirm that any external links
+ are still valid like so:
+
+ ```bash
+ cargo install cargo-deadlinks
+ cargo deadlinks --check-http -- --all-features
+ ```
+
+ If there are minor issues with the documentation, they can be fixed in the release branch.
+
+4. Bump the crate version in `frame-metadata/Cargo.toml` to whatever was decided in step 2.
+
+5. Update `CHANGELOG.md` to reflect the difference between this release and the last. If you're unsure of
+ what to add, check with the Tools team. See the `CHANGELOG.md` file for details of the format it follows.
+
+ Any [closed PRs](https://github.com/paritytech/frame-metadata/pulls?q=is%3Apr+sort%3Aupdated-desc+is%3Aclosed) between the last release and
+ this release branch should be noted.
+
+6. Commit any of the above changes to the release branch and open a PR in GitHub with a base of `main`.
+
+7. Once the branch has been reviewed and passes CI, merge it.
+
+8. Now, we're ready to publish the release to crates.io.
+
+ Checkout `main`, ensuring we're looking at that latest merge (`git pull`).
+
+ ```bash
+ cd frame-metadata && cargo publish
+ ```
+
+9. If the release was successful, tag the commit that we released in the `main` branch with the
+ version that we just released, for example:
+
+ ```bash
+ git tag -s v14.3.0 # use the version number you've just published to crates.io, not this one
+ git push --tags
+ ```
+
+ Once this is pushed, go along to [the releases page on GitHub](https://github.com/paritytech/frame-metadata/releases)
+ and draft a new release which points to the tag you just pushed to `main` above. Copy the changelog comments
+ for the current release into the release description.
