Updated May 24, 2019: Microsoft has now released an updated Edge Dev build that fixes the issue that caused the previous release from launching. The update may take time to register, but you should receive it soon if you've been affected by the bug. A look at the release notes has been added below.

The new Microsoft Edge may appear pretty polished, but it's still very much in development – and that's on display with the latest update to the Dev channel. Microsoft has confirmed that the latest Dev branch update for the Chromium-powered Edge "appears to stop some users from launching the browser after updating."

Here's a look at the release notes for the latest build:

  • The built-in translator has now rolled out to everyone. We'd appreciate it if you'd let us know how it works on your sites in your language. Just use the send feedback smiley button.
  • Dark mode, which many of you have enabled manually via a configuration flag, is now on by default for everyone. To see Microsoft Edge in dark mode, you will need to change your Windows or macOS system settings.
  • Keyword search for the address bar is now enabled. When you begin to type the "keyword" for a search engine into the address bar, you will be reminded that you can press tab to search using that engine. You can also type the entire keyword and press space to enter keyword search mode. If you continue typing and press enter, you will navigate directly to search results for that search engine. You may also see search suggestions from that engine as you type. Keyword search is available for all search engines you install or which are automatically detected for you as you browse. To manage search engines, open Settings, then Privacy and services, then Address bar, then Manage search engines. Here you can add or delete search engines AND customize the keyword used for them.
  • Added a "Close Microsoft Edge" option in the "Settings and more" menu
  • Improved dark theme support in Browser Task Manager
  • You can now tab to address bar icons which indicate blocked site permissions
  • Apps now appear in the same order on the apps menu and the apps page
  • Updated the keyboard focus rectangle so that it's more clearly visible
  • Fixed an issue that was causing high CPU usage while the browser was idle.
  • Fixed an issue where extensions couldn't alter video playback speed.
  • On the download page, individual download cards no longer change height as you tab through them.
  • Removed the "Unknown" option from the language dropdown menu in the translator
  • Fixed an issue where encrypted video only appears as a black screen.
  • Fixed an issue where clicking on menu items sometimes doesn't do anything.
  • Fixed a crash when enabling sync.
  • Fixed a crash during the first run experience.
  • Fixed an issue where the Settings page crashes due to a corrupted user profile.
  • Fixed a crash when opening Settings while in a guest browsing session

At one update per week, the Edge Dev channel is Microsoft's secon most frequently updated branch, following the Canary channel. While the browser is in preview, issues like this are expected to pop up. Microsoft is planning to open a new branch, the Beta channel, soon, which will see an update every six weeks.

If you want to give the latest features a shot appears, you can download the Dev and Canary channels for Windows and Mac now.
