After long discussions we've decided to a) rename version to stream, b) release to version, c) make the new version an integer, and d) make name, stream and version optional -- these should be autofilled by the buildsystem using the repository name, branch name and VCS commit timestamp.
Implemented in 28b4ce675a1b773e72ed9781cd06ab37c2f25cb0.
