OpenClaw 2026.9.5 upgrades its database and requires a backup first

Your move: Back up before you update; older builds can't open the new database

OpenClaw 2026.9.5, released September 19, 2026, upgrades agent databases to a new schema (schema 21) that older builds can't open. The release notes say to make and verify a backup before upgrading: going back afterward means restoring that backup with the matching older build, since reinstalling an older package alone won't undo it. Anyone updating from 2026.9.2 needs to follow a separate manual schema-upgrade step. The release also adds "Atomic Updates" that check the next version before switching over, lets you install or reload plugins without restarting the Gateway, and now asks for your explicit "Yes" before its AI-based triage agent tries to repair a failed update, instead of running on its own.

Why it matters

If you self-host OpenClaw, back up your database before installing this update, not after. Going back to an older version isn't as simple as reinstalling the old package once you've upgraded, so this is a real one-way step if you skip the backup.
