We have just released IronPython 1.0 Beta 5. This release focuses primarily on improving IronPython’s performance.

As usual there are also a good number of bug fixes (primarily focused on community reported bugs). There was also one significant API change in the .NET <-> Python interoperability area:

今回の修正はパフォーマンスの改善がメインのようです。他に、.NET と Python をつなぐ API にも変更が加えられたようです。
