📝 Walkthrough

Walkthrough

A new exported function isExactVersion(version: string) was added to the versions utility module. The function validates whether a provided version string represents an exact version number. Accompanying test coverage was introduced in the test suite, verifying that the function returns true for exact stable and prerelease versions, and returns false for version ranges, dist-tags, and invalid strings. This addition expands the public API surface of the versions utility without modifying existing functionality.
