Why is 1.10.0 newer than 1.4.2?

Each part is compared as a number, not as text. 10 is greater than 4, so 1.10.0 is newer, even though '1.4.2' looks larger alphabetically.

How does bumping work?

Bumping major resets minor and patch to 0; bumping minor resets patch to 0; bumping patch increases only the patch, following the semver rules.

Are pre-release versions handled?

Yes. A version with a pre-release tag (like 1.0.0-beta) is treated as lower precedence than the same version without it, per the spec.

About the Semantic Version Tool

Semantic versioning uses MAJOR.MINOR.PATCH to signal the impact of a release, with optional pre-release and build parts.

This tool parses a version into its parts, bumps the major, minor or patch, and compares two versions using the correct numeric rules.

It helps you avoid the classic mistake of treating 1.10.0 as older than 1.4.2.
