Standard npm caret dependency: allows minor and patch updates up to next major breaking version (React 18 ecosystem).
SemVer 0.x rule: minor version bumps in 0.x are considered breaking changes (0.4.2 to 0.5.0 is breaking).
Cargo SemVer rule: For 0.0.x versions, any patch change is breaking. Evaluates strictly according to Rust cargo rules.
Verify that your current base version: matches the expected string format. Load a built-in sample preset to compare structural formatting.
Check the prerelease identifier tag: setting in Semantic Versioning (SemVer) Calculator & Matcher to ensure encoding, precision, or specification version matches your target runtime.
Allows changes that do not modify the left-most non-zero element in the [major, minor, patch] tuple:
Allows patch-level updates when minor version is specified:
