Version numbering#

MFEprimer CLI releases on GitHub use Semantic Versioning (MAJOR.MINOR.PATCH). Spec: semver.org.

How we bump within 4.x#

Bump When
MINOR (4.54.6) Compatibility impact — existing scripts or parsers must change (for example a breaking *.spec.tsv column layout)
PATCH (4.5.04.5.1) No compatibility burden — bug fixes, robustness, optional enhancements, smarter defaults that keep old usage working
MAJOR (45) Ecosystem-level incompatibility; rare while we stay on 4.x

Before tagging, ask: will documented existing usage break? If yes → at least MINOR. Otherwise → PATCH. Do not bump MINOR only because a change “feels big” (example: auto-detect query -k shipped as v4.5.1, not 4.6.0).

Recent examples#

Version Why that level
