description: How to update your code when upgrading to a new version of Rerun

Rerun does not have a stable API yet, so most releases have breaking changes.
When you upgrade across several versions, read the guides for every version in between, oldest first.

## Rerun 0.34 and later

For Rerun 0.34 and later, breaking changes and how to migrate are listed in the "Breaking changes" section of each release in the [changelog](https://landing-git-codex-site-metrics-improvements-rerun.vercel.app/docs/changelog.md).
Some releases also have a separate migration guide:

- [Migrating from 0.38 to 0.39](https://landing-git-codex-site-metrics-improvements-rerun.vercel.app/docs/reference/migration/migration-0-39.md)
- [Migrating from 0.37 to 0.38](https://landing-git-codex-site-metrics-improvements-rerun.vercel.app/docs/reference/migration/migration-0-38.md)
