* REGRESSION: Links in the active content warnings are now legible in dark mode
* DEV: Developer Mode can now be turned on and off while the app is in Restricted mode
* DEV: Developer Mode now also turns off the ZIM assets cache for as long as it is on, and marks those buttons unavailable
* FIX: A misspelt setting name meant the app ignored user choice to disable assets cache
* FIX: Reset app no longer fails with an error when no Service Worker is controlling the page
* SECURITY/REGRESSION: Archives no longer loaded in SW mode in the background before user has chosen the trust level
* FIX: The content injection mode is now checked against the modes the app actually supports, so an unrecognized value can no longer leave the app in an invalid state
* DEV: Harmonized the checks on the content injection mode string with upstream, and removed vestigial handling of a mode this app does not implement
* DEV: Added unit tests covering the validation of the content injection mode value
* SECURITY: Settings supplied in the app's URL are no longer saved permanently, apart from the few the app passes between its own windows, and source verification can now only be changed in Configuration
* FEATURE: New setting to show a title bar when the browser draws the window controls overlay over the app, restoring the choice that recent versions of Edge removed
* FEATURE: In-app library can now browse the whole ZIM catalogue as well as by category, so archives that declare no category in their metadata can now be found
* FEATURE: New filter textbox in the in-app library to narrow the list as you type
* ENHANCEMENT: When the app supplies its own title bar, it stays in place as the navigation bar slides away on scroll
* ENHANCEMENT: macOS packages are now distributed as disk images (`.dmg`) for easier installation
* ENHANCEMENT: The top navigation bar now matches the height of the window controls overlay, and follows it when the user shows or hides the title bar
* FIX: The library's Language, Subject and Date filters now apply instantly, without rebuilding the list, and no longer reset when returning to the list
* FIX: Auto-updates now enabled for the macOS Electron app
* FIX: The colour of the window frame now follows the app's navigation bar, so the window buttons no longer sit in a contrasting block in light mode
* FIX: Popover previews of Wikimedia article links now work when reading the archive with the experimental libzim reader
* FIX: The popover's open-in-new-window icon now opens a new window or tab when reading with the experimental libzim reader, instead of loading the article in place
* FIX: Opening an article in a new window or tab no longer blanks or hides the article you were reading in the original window
* FIX: Zimit (classic) archives read with the experimental libzim reader no longer sometimes stay hidden after a page loads
* FIX: The last-visited page is now remembered correctly when reading with the experimental libzim reader
* FIX: Launching a ZIM by double-clicking it in the OS no longer opens the archive twice, so the file permission request and the "trusted source" security prompt are no longer shown twice
* FIX: The Windows Setup and web installers now register the ZIM file type (including the first part of a split archive), so archives can be opened by double-clicking them in File Explorer
* FIX: When the Windows Store app is launched by double-clicking a ZIM file, the stored location of the previously opened archive is now cleared as intended, instead of being left in place
* REGRESSION: Restored the top navigation bar's adaptation to the window controls overlay, which was lost in the Bootstrap 4 migration (latest browsers turn the overlay on by default, so the window buttons were covering the app's controls)
* REGRESSION: Restored the draggable area in the top navigation bar, which was lost in the Bootstrap 4 migration, so the app window can be moved again when the window controls overlay is shown
