In order to automate downloading of a specific platform build asset, it would be easier if the assets did not contain the build number. This would allow referencing the repository using the latest feature in GitHub.

To link directly to a download of your latest release asset that was manually uploaded, link to /owner/name/releases/latest/download/asset-name.zip.
