Version information

Version information embedded in the software needs to be made deterministic. Counter-examples are using the current date or an incremental build counter.

The date and time of the build itself is hardly of value as an old source code can always be compiled long after it has been released. It’s best when version information gives a good indication of what source code has been built.

The version number can come from a dedicated source file, a changelog, or from a version control system. If a date is needed, it can be extracted from the changelog or the version control system. A cryptographic checksum can also help to pinpoint the exact source content. This makes Git commit ids good candidates as part of version information.
