# Updates, rollback and uninstall

Change application versions without losing project work.

## Before updating

Save projects, stop active jobs and keep a backup. Read release notes and platform requirements. Download only a listed immutable artifact, verify its checksum and signature where applicable, and retain the previous qualified version.

## Verify the new version

Install using the platform's documented installer. Reopen a small project and verify the displayed version, native startup, conversation recovery and activation. Do not edit a content-addressed application object in place or overwrite a running application with arbitrary source files.

## Rollback

Use the previous verified installer or documented rollback target if the new version fails. Preserve projects and histories made since the update; do not blindly replace user data with an old application backup. Report both versions and the observed regression to support.

## Remove the application

On Windows, use Installed apps or the supplied uninstaller. On Linux, use the removal instructions matching the package format. Keep project and user-data deletion separate and explicit. Uninstalling or deleting local credentials does not cancel a paid subscription—manage renewal through billing first.
