Starting with the first officially released version of this project, v3.4.0, the version numbering scheme is intended to be as follows: v<major>.<minor>.<bug-fix>.

So:

• Going from version v3.x.x to v4.0.0 would imply some "major" functionality change or addition.
• Going from version v3.4.x to v3.5.0 would imply some "minor" functionality change or addition.
• Going from version v3.4.x to v3.4.x+1 would imply no functionality change other than a bug fix to make v3.4.x what it "should have been".

For example, version v3.4.1 is a bug-fix release that changes no script or tool functionality whatsoever, but instead fixes a "bug" with where the external documentation (installation information, usage notes, FAQ, etc.) is located.

See Semantic Versioning 2.0.0 for further guidelines.
