Hello IronPython Community,

We have just released IronPython 2.0 Alpha 5. Over the past month our team has been busy fixing bugs which were typically chosen by the number of votes on CodePlex. A little over forty CodePlex Work Items and around twenty bugs reported internally were closed since the release of IP 2.0A4. There were no major new features added unless you count the fact that we ported the standard ‘array’ module from IronPython v1.1 to v2.0. This now means that all of the standard modules in v1.1 are available in the latest 2.0 tree.

Specifically the following CodePlex Work Items were resolved and I’d like to extend our team’s thanks to everyone who reported, commented, and voted on these:

IMPORTANT NOTE
Internally we have migrated our Visual Studio project and solution files over to a Visual Studio 2008 beta release. While we’ve modified these files in the source distribution of IronPython to be compatible with Visual Studio 2005 and the msbuild tool, it’s possible we may have missed something. If you experience any problems building IronPython from VS tools please let us know.
