Hey @djmango, thank you!

I have a few questions. This PR uses the same binary for Windows Arm64 as it does for x86. I double-checked the README inside the zip that gets downloaded:

release-essentials build configuration: 

ARCH                      x86 (generic)

Have you found that this works on Arm64 Windows? Do you think it's running in some kind of compatibility mode, versus a native Arm binary?

Also, could you please add this runner to Github Actions? https://github.blog/changelog/2025-04-14-windows-arm64-hosted-runners-now-available-in-public-preview/#how-to-use-the-runners I'll approve the workflows to run so that we can run the full test suite on Arm.

hey ! sorry for my needs i need to switch from ureq to reqwest so this pr might not make a lot of sense anymore if you want to avoid that change

Hey no worries! We switched from reqwest to ureq a little while back to keep library dependencies super minimal and lightweight. Want to stick with ureq for that reason but it's a good call to swap it out for your use case if it works better for you.

Also looks like CI did pass. I'm guessing Windows has some kind of emulation under the hood that allows running x86 binaries on arm64. That makes this a quick win, I'd look to merge it without the reqwest change.
