About this tool
Semantic versioning: MAJOR.MINOR.PATCH. Bump major when you break compatibility, minor for new compatible features, patch for fixes. At 0.y.z the rules shift — the public API is still settling, so breaking changes typically bump minor until 1.0.0.
npm ranges (^, ~, compounds) control what npm update can pull. Caret is the default in package.json — permissive within a major. Tilde is patch-only on the same minor line.
