  • The addition of more C-based standard modules such as cmath and _winreg
  • Significant improvements in importing compatibility and features
  • Distribution of IronPython under the Microsoft Public License which has been approved by OSI
  • Performance improvements. On that note, a new Wiki page has been created for IronPython performance reports – see
