We have just released IronPython 2.0 Alpha 1. IronPython 2.0 will be the first release of IronPython built upon a common dynamic language runtime (DLR) as well as targeting version 2.5 of Python. One major focus during this release will be further improving our conformance with CPython. We’ve already made several improvements, for example one is that our type system no longer contains a hierarchy of types: now type(type) is type. We have also fixed a number of issues related to various statements such as imports and function definitions inside of exec or eval. There have also been a number of other small issues fixed that our users reported to us.
