# Version Numbering

joca follows the three major tenents of the [SemVer](https://semver.org/spec/v2.0.0.html) method of software versioning.

> Given a version number MAJOR.MINOR.PATCH, increment the:
>
> - MAJOR version when you make incompatible API changes,
> - MINOR version when you add functionality in a backwards-compatible manner, and
> - PATCH version when you make backwards-compatible bug fixes.
>
> Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format. (Preston-Warner, 2013)

Build metadata MAY be denoted by appending a hyphen and a series of dot separated identifiers immediately following the patch or pre-release version.

Build version follows [RFC-1912 section 2.2](https://tools.ietf.org/html/rfc1912#section-2.2):

> The recommended syntax is YYYYMMDDnn
> (YYYY=year, MM=month, DD=day, nn=revision number. This won't
> overflow until the year 4294" (Barr, 1996)

Example: `1.23.4-2018033000`:

- Major version `1`
- Minor version `23`
- Patch version `4`
- Build number `2018033000` => `2018` `03` `30` `00`
