• windows artifacts (.exe) are stored @ appvoyer build artifacts
• macOS artifacts (.dmg) are stored @ git (osx-deploy branch)

There shall be one place to store artifacts.

• Each of these artifacts shall be persisted at one common place/provider.
• Releases (tags) and continuous artifacts shall have different places/repositories.
