Microsoft has just published a new Build 21313.1000 (rs_prerelease) in DEV CHANNEL ( 21H1 ) via Windows Update for Insiders.

NOTE: Version 21313 will not be offered to ARM64 devices due to an application compatibility issue.

Updates for developers and other notes from Microsoft:

Broaden news and interests to more languages ​​and markets

We’ve heard your comments!  Today, we’re excited to announce that we’re expanding the news and interests taskbar experience to a wider set of languages ​​and international markets.  Previously, the experience was only available in the United States, Canada, Great Britain, Australia and India.  This now means that news content, weather forecasts, sports and financial updates will be based on your location anywhere in the world!

Changes and improvements

• Based on the feedback and to align with the fact that Dev Channel versions do not correspond to a specific version of Windows 10, we’ve updated the version name shown to now be Dev.
• We’ve heard comments that it’s not clear how to turn off News and Interests if that’s your preference.  To resolve this issue, we’ve changed the “Hidden” option in the taskbar context menu to now say “Disable” to make this functionality clearer.
• Based on the feedback, we’ve made some small tweaks to the  new app launch animation  to improve speed and make it a bit smoother.
• The improvement to the candidate bar on the touch keyboard  announced last week  where it shows up to 5 candidates and centers them above the keyboard has started to roll out.
• The new voice typing experience  announced in September  has started rolling out to all Dev Channel insiders.  Press the Windows key plus H if you want to try it in one of the supported languages.
• The change to pin items in our  updated clipboard history design  (inside the emoji picker) is now rolling out to everyone in the development chain.
• We’ve made a few more updates to our emojis research teams based on feedback, including that the lineup will now return all 3 technologist emojis and RIP will now return the tombstone emoji.  We have also updated the Russian search so that emoji with the letter ё in their keywords can now also be found using the letter e.  Please keep the comments coming!
• We are currently removing the ability to copy and paste a screenshot directly into a File Explorer folder due to an issue discovered through feedback from Windows Insiders.  We hope to re-enable this feature in a future update after fixing this issue.  (This change was also released for Windows Insiders in the beta channel as part of the  recent Windows Feature Experience Pack update  .)
• As part of  our ongoing iconography work  , this release introduces a new design for our Narrator icon.

The new Microsoft Edge to replace Microsoft Edge Legacy:

With the release of Windows 10 Insider Preview  Build  21313,  Microsoft Edge Legacy will be replaced by the new Microsoft Edge.  This will be the case for versions of Windows 10 Insider Preview going forward.

With Microsoft Edge, it’s time to wait more.  You get world-class performance, with more privacy, more productivity, and more value when you’re on the water.

And if you want to try out upcoming features of Microsoft Edge, join the Microsoft Edge Insider program.  Be among the first to see what’s new by downloading Microsoft Edge Canary, Dev, or Beta channels  from the Microsoft Edge Insider website.

• We are looking at reports of update process hanging for long periods of time when trying to install a new version.
