semver rules

How:

• The Node package manager (npm)
• Golang Modules

handles semver range definitions.

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.

Rule example	Description	Expanded form
0.1.2	An exact version match of MAJOR.MINOR.PATCH.	0.1.2
^0.3.8	A version match of 0.3.8 plus incremental MINOR versions.	>= 0.3.8 < 1.0.0
~0.2.5	A version match of 0.2.5 plus incremental PATCH versions.	>= 0.2.5 < 0.3.0
