Today, Microsoft has released two new Windows 11 builds, one for the beta channel (build 22623.875), while the second build is for the developer channel. The new incremental upgrade is labeled with the 25231 build number and is available in the developer channel. It is not a big upgrade, instead, a minor upgrade bringing available features to all insiders. Read along to know more about Windows 11 build 25231.
Microsoft is pushing the new dev channel build with Windows 11 Insider Preview 25231.1000 (rs_prerelease) build version. As it is an incremental upgrade, you can quickly upgrade your system to the new build.
In terms of changes, the new dev channel build brings the touch-optimized taskbar to all insiders, which was previously available to a small set of users in the dev channel. If you have a touchscreen device running on Windows 11 (the latest dev build), then you can now use the new taskbar, which collapses to a smaller size, and will be expanded later using a swipe gesture. Currently, the feature is limited to the dev channel, if everything goes fine the feature will be released to the beta channel.

Apart from the touch-optimized taskbar, the new dev build brings a language-neutral word list to more users, the list will be synced across all devices using the same Windows account. Another feature coming to more users is the cloud suggestion feature Simplified Chinese IME.
The latest dev build addresses a big list of issues available on the previous builds, the list includes a new tooltip is showing when hovering the mouse over sound icon in the Quick Settings, fixes the font used in Wi-Fi section in Quick Settings, fixed an issue which sometimes led to crashes in certain apps, and more.
