Microsoft has released a new Windows 11 Insider build 25120 to the Dev Channel. This is the Sun Valley 3 development for Windows Insiders, which will eventually become the version that is released in 2023. The firm highlighted a few things with this build, firstly, unlike the previous build, it's now available for ARM64 PCs, and there are also ISOs that can be downloaded.

Windows Server vNext build 25120 was also released yesterday, possibly indicating that these editions will sync up.
