- Own CSS is parsed on write only. A page whose stored CSS no longer passes a stricter rule answers 200 and opens in the editor; that one block loses its CSS. A document read several times in one request is validated once. - Settings and theme refuse a write from an outdated form. - A backup fails when a media file does not arrive completely and leaves no half directory behind; rotation counts intact backups only. - The archive update takes its backup behind the maintenance page. - A package import puts all media in place before removing the old ones, reports honestly when that fails and keeps a maintenance state that was already on. - Restoring replaces the SQLite file in one move and points at pending migrations. - Six irreversible actions ask first, in a dialog of the admin's own. - Ctrl+S in the editor takes the field being typed in along; Delete no longer removes a block while a dialog is open.
