Updates from Gitea, step 4: the Firmware page shows the project's releases

Latest release (checked on Enter, or c), Older releases (the last ten,
newest first), a release page with the tag's message, and an install
dialog; going back to an older release asks differently. A failed check
someone asked for shows a Toast. A Debug Build shows the latest release
and says it can't install it: it would take its console away.

Tried on the device: a check, the list, the release page, the dialog
(Cancel is the default; Back cancels), and the install from the screen
with its progress screen, then the restart into the release build and its
confirmation.
