I build Zed for Windows aarch64 from source -- works great, though the build process is quite slow on my 16GB Surface Pro. Definitely hoping for official binaries, though!
I think I got as far as installing the Visual Studio Installer so I could install Visual Studio and I just bailed on that whole thing, lol. I'll have to take some time out on a weekend to take another look :)
I love my ARM Surface Pro, and Zed would make a wonderful editor on this hardware. If anyone from Zed is reading this, please think about it!
