Last week, Microsoft announced that Windows 10 20H1 is coming to the Fast ring, rather than 19H2, which is what was expected. 19H2 is the next feature update for the OS, which will arrive later this year. 20H1 is the one coming after that, arriving in the first half of 2020.
The Skip Ahead subset of the Fast ring has been testing out 20H1 for some time now, and now it's being merged with the regular Fast ring. While there's limited space in Skip Ahead, anyone can join the Fast ring. That means that for the first time, anyone can test out builds from the 20H1 development branch.
That being said, Microsoft today released Windows 10 Insider Preview build 18875 to the Fast ring.
There's not a whole lot that's new still; we can probably expect to hear more about what's coming around the Build timeframe. Here's the full changelog from build 18875:
East Asian Microsoft Input Method Editor (IME) Improvements:
The New Japanese IME is now available to all Insiders in Fast!
During 19H1, we announced we were working on a new Japanese IME. We got a lot of great feedback, and the IME was taken offline for a time while we worked on improving the experience based on what you’d told us. Today the IME – now more secure, more stable, with improved game compatibility, and more – is once again available for all Insiders starting with this build. If you speak Japanese, please take some time to evaluate how it feels to use the IME (with all the improvements) for daily usage, and let us know what you think! If you already were using the Japanese IME, you’ll automatically have the new one when you install this build – if you weren’t already using the Japanese IME, you can add it by going to Languages Settings and adding Japanese to the list.
New IMEs are available for Simplified and Traditional Chinese!
Just like the Japanese IME above, we’ve been working on refining your Chinese typing experience, and are happy to share that we have new versions of the Chinese Simplified IMEs (Pinyin and Wubi), as well as the Chinese Traditional IMEs (Bopomofo, ChangJie and Quick). We’ve improved the security and reliability by redesigning how they work with applications. You’ll also notice we’ve added a cleaner interface for the candidate window and settings pages. Improved and renewed settings of the IMEs are available in the Settings app. If you’re using one of the IMEs and you’d like to check it out, the fastest way there is to right-click the IME mode indicator in the taskbar and select Settings (you can get there from the Language Settings page by clicking the language, and going into options). Looking forward to hearing what you think about it!
This build is replacing build 18362 in the Fast ring, and it's worth noting that the old build is the release candidate for the Windows 10 May 2019 Update. This is your last chance to jump off of the Windows Insider Program without doing a factory reset. It's also worth noting that this opportunity typically comes every six months, but since we're testing an update that won't be available for another year, this opportunity won't come again until spring 2020.
