Architectures short hand not working as expected

So, recently saber snap got arm64 support. We used the shorthand to build it in the store. But, snapcraft builder is building only for amd64.

I’m seeing the same behavior:

The shorthand notation:

architectures: [amd64, arm64]

only triggers an amd64 build on snapcraft.io.

Whereas the explicit notation:

architectures:
  - build-on: amd64
    build-for: amd64
  - build-on: arm64
    build-for: arm64

triggers a build for amd64 and arm64.

@ogra is it a temporary bug?

I have no idea I actually even thought the shorthand way was dropped for core22 snaps, I was not aware it would be supposed to work

https://snapcraft.io/docs/architectures

It’s specifically mentioned here for both core20 and core22 and was suggested to me by upstream. So, I thought to bring it up here.

Yeah, it was supposed to be dropped but was not, which is my mistake.
