Microsoft has today released two new builds for Insiders in the Fast ring and Skip Ahead rings today. This is a significant release, as it marks the final development stages of Redstone 4 as well as the first development stages of Redstone 5. Insiders in the Fast ring are receiving build 17101 from the RS4_RELEASE branch, whereas Skip Ahead users are receiving 17604 from the rs_prerelease branch, a Redstone 5 build.

Right now, both builds are more or less identical since development has only just been forked. Here's what's new:

  • Emoji design updates: Based on your feedback and to improve consistency, we've made adjustments to the design of some of our emoji. Examples of updated emoji include:

  • Emoji search comes to more languages: Earlier in RS4, we updated the Emoji Panel to support browsing and picking emoji in many new locales. With today's build, we're bringing search support to more locales too! Now you can find an emoji by keyword in over 150 locales, including English (Great Britain), French (France), German (Germany), Spanish (Spain), and more. This will help you get the emoji you want easily and quickly. As a reminder, to bring up the Emoji Panel set focus to a text field and press WIN + (period) or WIN + (semicolon).
  • UWP File System Access: With this build we're giving you more control so you can now decide which UWP apps can access your full file system. Particular UWP apps will be granted permission to have broad file system access. This capability will be granted on a per app basis by Microsoft. If a UWP app has the broad file system access restricted capability, you will receive a consent dialog prompting you to accept or deny the request.

As always, you can check out the full changelog at the Windows Blog!

  • Redstone 5! Yes
  • I never understood people getting exciting for the second next thing when the current next thing isn't done yet.
  • RS4 is done, other than bug fixes. For those who like new features, it's currently (or at least soon) RS5 or nothing.
  • So it begins. there also letting a few more join in skip ahead
  • Enhancing UWP capabilities. Good.
  • Too slowly and near or at UWP irrelevance.
  • Am I the only one that finds Microsoft's design for emoji really ugly? Would much rather they align with everyone else's style and removed the black borders
  • A lot of thought went into makin those emoji. The black boarders allow the emoji to be easily seen on both dark and bright backgrounds. I also like the minimal style more than the cartoony one the others use. Reminds me of Metro.
  • Cant say ive ever had difficulty in discerning emoji on either a dark or bright background nor heard of anyone complaining about it. They just stick out like a sore thumb in a lineup of other companies styles, Naturally the design is subjective etc, perhaps without the black border they would be much less jarring, but i dont think the design of the graphics are really that much more or less cartoony than other companies 
  • I hate emoji, period. I wish they'd never been invented.
  • You know they predate other writing systems right... so your wish would be humans never started writing at all.
  • They need the guy who designed windows live messenger emojis. From my perspective every emo was describing how you actually feel. :$ :O :@ :P :S :D
  • I had only heard about 17101 via Twitter, so when I fired up my Surface Pro and saw it downloading 17604 I got a little nervous. I'm glad it's actually intentional.
  • 17101 is rs4_release branch, RTM is getting closer...
  • Yeah well, End of March is getting closer :P
  • And.... still stuck on 17025 here..........
  • I got stuck on an earlier one, then did a 'reset'
  • Windows 10 Mobile?
  • You're kidding... Right??
  • His mum finds him amusing 😉
  • No more Windows 10 releases will be made, except security fixes rolling out if Microsoft feels the need for it. I only expect to see that if something major shows up, while minor flaws will probably be left alone (just a hunch). There was an article (or more than one) here on Windows Central on Windows 10 Mobile getting no more updates, so yes: that’s it.
  • There is a recent article on here about W10M getting an update, so yes W10M is still getting updates but no new features.
  • Soundblaster's Z Pro studio lost almost all of the features after Windows update! WTF?    
  • Have to re-install my SB soundcard drivers after every Insider update as it changes from 5.1 to plain stereo.
  • sometimes sound disapierded after update, but simple drivers reinstall works. Now it's complete disaster
  • Did they fix the boot loop issue?
