README.md:57

• The placeholder 'vX.Y.Z' may be confusing; consider using a semantic version placeholder (e.g. 'v0.2.0') to clearly indicate the intended version format.

Tag on GitHub, copy over the correct version (format vX.Y.Z) and CHANGELOG content.

CHANGELOG.md:5

• [nitpick] Consider standardizing the capitalization of 'NMECR' for consistency with other documentation references.
