Hello Windows Insiders,
Today we are releasing Windows 11 Insider Preview Build 25346 to the Canary Channel. We are releasing ISOs for this build – they can be downloaded here.
If you miss this month’s Windows Insider webcast featuring the Phone Link team, you can watch it on demand here: https://aka.ms/April2023WIPWebcast.
REMINDER: As builds released to the Canary Channel are “hot off the presses,” we will offer limited documentation for builds flighted to the Canary Channel (no known issues for example), but we will not publish a blog post for every flight – only when new features are available in a build. And like the previous Canary Channel build, this build has a few new features and changes to document.
Content Adaptive Brightness Control (CABC) is already a feature that users are familiar with. This feature in Windows 11 will dim or brighten areas of a display or monitor based on the content being displayed with the goal of striking a balance between reduced power consumption with visual experience to save battery life. Starting with this build, we are allowing this feature to run on devices such as laptops and 2-in-1’s that are plugged into a charger. For most users, this change won’t be noticeable and should reduce energy consumption.
This feature can be adjusted via Settings > System > Display under “Brightness & color” and through a drop-down menu with 3 options: Off, Always, and “On Battery Only”. For battery powered devices such as laptops and 2-in-1’s, the default is “On Battery Only”. We encourage Insiders across laptops, 2-in1’s, to try the “Always” option and give us feedback on the visual quality of CABC so we can ensure it is properly tuned.
Please note: Content Adaptive Brightness Control (CABC) needs to be enabled by the OEM (the manufacturer of the device). As a result, this feature is not available on all laptop or 2-in-1 devices.
FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Display and Graphics > Adaptive Brightness.
You can download the latest Windows Insider SDK at aka.ms/windowsinsidersdk.
SDK NuGet packages are now also flighting at NuGet Gallery | WindowsSDK which include:
These NuGet packages provide more granular access to the SDK and better integration in CI/CD pipelines.
SDK flights are now published for both the Canary and Dev Channels, so be sure to choose the right version for your Insider Channel.
Remember to use adaptive code when targeting new APIs to make sure your app runs on all customer machines, particularly when building against the Dev Channel SDK. Feature detection is recommended over OS version checks, as OS version checks are unreliable and will not work as expected in all cases.
The Canary Channel is the place to preview platform changes that require longer-lead time before getting released to customers. Some examples of this include major changes to the Windows kernel, new APIs, etc. Builds that we release to the Canary Channel should not be seen as matched to any specific release of Windows and some of the changes we try out in the Canary Channel will never ship, and others could show up in future Windows releases when they’re ready.
The builds that will be flighted to the Canary Channel are “hot off the presses,” flighting very soon after they are built, which means very little validation and documentation will be done before they are offered to Insiders. These builds could include major issues that could result in not being able to use your PC correctly or even in some rare cases require you to reinstall Windows. We will offer limited documentation for the Canary Channel, but we will not publish a blog post for every flight – only when new features are available in a build.
Our Canary Channel won’t receive daily builds; however, we may ramp up releasing builds more frequently in the future.
The desktop watermark you see at the lower right corner of your desktop is normal for these pre-release builds.
