It would be nice to have builds uploaded be identified by 32-bit or 64-bit along with platform (like Gamejolt does currently). Currently games with both 32-bit and 64-bit builds that are separately uploaded for a single platform will continuously update from one to the other on the itch launcher.

 excellente idée

Games should not update between architectures in our app if you use butler to upload to the same build. Butler will let you have a chain of patches/updates that will ensure that only that “build” is updated.
