 ## Shipping prerequisites
 
 - The region profile and timezone mapping wait on omarchy #13690 and omarchy-iso #241; input methods (omarchy #14433, omarchy-iso #237) are merged. The language screen, CJK console, Chinese UI, developer mirrors and China apps exist only on the `omarchycn` branches: build a test ISO with `./bin/omarchy-iso-make --local-source ../omarchy ../omarchy-pkgs` from `omarchy-iso/`.
-- A local-source ISO builds `omarchy-dev` and `omarchy-settings-dev` under the published version number, so the next edge release would replace them with builds that lack this code. Until these branches ship upstream, the ISO pins the local builds with `IgnorePkg`, a `pre-refresh-pacman` hook and an ALPM hook that aborts any transaction replacing them (omarchy-iso README). Pinned machines get no Omarchy updates.
+- A local-source ISO builds `omarchy-dev` and `omarchy-settings-dev` under the published version number and does not pin them, so the next published release replaces them on `omarchy update`. Local test ISOs are for testing only.
 - `stable-mirror.omarchy.cn`, `rc-mirror.omarchy.cn` and `mirror.omarchy.cn` resolve and serve `core.db` (checked 2026-10-09).
