While in general terms I realize this is a sub-version number that's bumped based on patches that don't bump the major version, is there a more exact definition for this?
Must the number match the number of patches applied for example?
Or is this a general term that each project uses slightly differently?
The closest we have to an accepted definition of "patch level" comes from semantic versioning (semver), where a patch level is the third component of a version number, which gets increased if a release only contains backward compatible bug fixes.
However, semver is not universally used and others may use the term "patch level" in other ways.
