* Zettelstore conforms somehow to the Standard [[Semantic Versioning|https://semver.org/]].

  The first three digits contain the major, minor, and patch version as described in this standard.
* The first string contains additional information, e.g. ""dev"" for a development version, or ""preview"" for a preview version.
* The second string contains data to identify the version from a developers perspective.

If any of the three digits has the value -1, its semantic value is unknown.
Similar, the two string might be empty.
