# Releasing SlateDB

## Cadence

We aim to release a new version of SlateDB every 2 months. This is a guideline, not a strict rule. The actual cadence may vary based on the amount of work that has been completed.

## Proposal

Anyone may propose a new SlateDB release by opening a Github issue.

## Approval

[GOVERNANCE.md](GOVERNANCE.md) defines how a release is approved.

## Publication

SlateDB releases are published using a Github release action defined in `.github/workflows/release.yml`. To create a new release:

1. Go to the [release action page]https://github.com/slatedb/slatedb/actions/workflows/release.yaml
2. Input a version value in the format `X.Y.Z` and click `Run workflow`.

The release action will do the following:

1. Verify that the version adheres to the semantic versioning format.
2. Check out the latest code from the `main` branch.
3. Update the version in Cargo.toml to the specified version.
4. Commit the changes and push to the `main` branch.
5. Create a Github release with the specified version and auto-generated release notes.
6. Publish a release to crates.io.
