Because this 20H1 is in the early phase right now, there aren’t many new features, yet. However, there are improvements to Input Method Editor (IME) with simplified Japanese and Chinese support. Microsoft says: “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.”

In addition to the new input methods, here is a look at the other changes and fixes included with this build:

We fixed an issue that could result in a freeze on the lock screen if you interacted with the touch keyboard and then switched keyboard layouts.We fixed an issue resulting in Settings sporadically crashing in the last few builds.We fixed an issue resulting in some Insiders being prompted to setup their device after every reboot.We fixed an issue resulting in some of the text under Settings > System > Storage > Temporary Files being unexpectedly garbled in Chinese and Japanese.We’ve made a change in Timeline for keyboard-only users, so if you’re doing a search and haven’t opted in, you’ll no longer have to tab past the opt-in text before you can get to the search results.We fixed an issue that could cause certain applications to flicker if they were maximized and you launched the touch keyboard.We fixed an issue where, if the Photos tile was pinned to Start, it could potentially result in unexpected battery drain as the tile animation would trigger even if Start wasn’t open.

Remember this is a preview build in early development so you can expect several bugs and issues for users and developers alike. Make sure to read Microsoft’s full announcement for all changes, known issues, and workarounds.
