For #20675 and #25977. - [X] Changes file added for user-visible changes in `changes/`, `orbit/changes/` or `ee/fleetd-chrome/changes`. See [Changes files](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/Committing-Changes.md#changes-files) for more information. - [x] A detailed QA plan exists on the associated ticket (if it isn't there, work with the product group's QA engineer to add it) - [X] Manual QA for all new/changed functionality - For Orbit and Fleet Desktop changes: - [X] Make sure fleetd is compatible with the latest released version of Fleet (see [Must rule](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/fleetd-development-and-release-strategy.md)). - [X] Orbit runs on macOS, Linux and Windows. Check if the orbit feature/bugfix should only apply to one platform (`runtime.GOOS`). - [X] Manual QA must be performed in the three main OSs, macOS, Windows and Linux. - [x] Auto-update manual QA, from released version of component to new version (see [tools/tuf/test](../tools/tuf/test/README.md)).
