Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. diff returns 'major' when comparing versions across major version boundaries
  2. diff returns 'minor' when comparing versions across minor version boundaries
  3. diff returns 'patch' when comparing versions across patch version boundaries
  4. diff returns 'premajor', 'preminor', or 'prepatch' when comparing standard versions to respective prerelease versions
  5. diff returns 'prerelease' when comparing two prerelease versions with the same base version
  6. diff returns null when comparing two identical versions
  7. diff throws TypeError when invalid version strings are provided
  8. diff works with SemVer instance objects as input arguments
