Releases & migration notes

Deployment runbooks and migration notes for each Ark release, newest first. Each release lists the schema migrations, data backfills, and integration updates needed to move onto that version.

• Release 3.0.0

Standard upgrade checklist

Every Ark upgrade follows the same shape. Before you start a release-specific runbook, confirm you can tick these off:

1. Back up every affected database — releases may include destructive, non-reversible migrations. Roll back by re-deploying the backup.
2. Read the release-specific migration notes end to end before running any step.
3. Plan the integration updates called out for the release alongside your normal integration testing — none should require a rushed cutover.
4. Verify in a non-production environment first, then promote.
5. Keep your support representative in the loop for anything environment-specific.
