Insiders in the Canary Channel will receive Build 26052.1000 while Insiders in the Dev Channel will receive Build 26052.1100 (KB5035384) as we test delivery of a full build and a servicing update at the same time. There is no difference between the two of these as Build 26052.1100 does not include any additional code. (Arm64 devices in the Dev Channel will not receive Build 26052.1100.)
Starting today, Windows Insiders in the Dev Channel are being moved from receiving 23000 series builds to receiving 26000 series builds.
Insiders in the Dev Channel will gain a set of new features such as energy saver, scrollable quick settings, QR codes for Wi-Fi sharing, support for creating 7-zip and TAR archives in addition to ZIP in File Explorer, Windows protected print mode, voice clarity, along with recent Server Message Block (SMB) protocol changes and improvements to Windows Local Administrator Password Solution (LAPS), and improvements across Settings and improvements for Bluetooth and Graphics as well. Note that apps such as Tips and WordPad will be removed after upgrading to this build.
The Canary and Dev Channels receiving the same builds is only temporary. During the times in which the Canary and Dev Channels are on the same builds (e.g. Build 26052), the window is open for Insiders in the Canary Channel to switch to the Dev Channel. At some point in the future, the Canary Channel will jump to higher build numbers and the window will be closed.
