Edge Dev build 77.0.218.4 brings dark mode to Windows 7 and 8.1

Microsoft has released its weekly build of the new Chromium-based Edge browser to Insiders enrolled in the Dev channel for updates, bringing the version number to 77.0.218.4. As usual, the update includes some of the improvements seen in the Canary channel over the past week.

One of the most notable additions is a toggle for dark mode in the settings, which not only gives users the option to bypass the system setting, but also brings dark mode to older versions of Windows that don't have a system setting for dark mode. Here are the new features in this release:

  • Added more strings to the translation work
  • Prevent IE-Mode in Application Guard containers
  • Ability to set text size and background theme in Reading View is now under flag.
  • Ability to use dark mode on downlevel Windows versions 7, 8 & 8.1
  • Search box now clears content with Esc or “x” button

There are also some fixes for improved reliability:

  • Fixed a crash on Extensions page.
  • Fixed a crash in API keys
  • Fixed a crash while opening PDFs
  • Fix crash in Sync service
  • Fix crash due to cached call in renderer
  • Fix deadlock in Windows, where Microsoft Edge blocks shutdown.
  • Fix crash in JSON parser

And finally, fixes for improved behavior:

  • Fix preventing URL redirection in Application Guard.
  • Fix to prevent creation of database until needed (performance)
  • Subpage headers display the number of search results.
  • Fix to close Profile UI on sign-in
  • Dev Tools support using OS theme color on Windows 10
  • Fix color contrast for selected favorites
  • Fixed Copy / Paste keyboard shortcuts on macOS
  • Fix for z-order on history page
  • Fixed transparency issue on First Run Experience
  • Strengthened launching logic for PDF to specified file names and paths
  • Fix to show FavIcons in Favorites management page.
  • Fix for account removal in Identity
  • Fix for sign-in where account pop-up was not topmost window.
  • Fix for data imports from Chrome and Edge during First Run experience.

In addition to the changes made to the browser, Microsoft has also created a new Enterprise section on the Edge Insider website, where organizations can download offline installer and a policy file. The website also now supports more languages.
