Frequently Asked Questions

What is Semantic Versioning?

SemVer uses MAJOR.MINOR.PATCH — major for breaking changes, minor for new features, patch for fixes. Pre-release tags use a dash like 1.0.0-beta.

Can I compare versions?

Yes, enter two versions and the tool tells you which is newer based on the SemVer precedence rules.

Why is SemVer important?

It communicates compatibility — knowing whether an update is breaking, adding features or fixing bugs helps you upgrade safely.
