<p class=MsoNormal>Hello Python Community,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The IronPython and Dynamic Language Runtime teams are proud
to announce the release of IronPython 2.0 final. IronPython 2.0 is the
culmination of nearly two years worth of work resulting in a CPython 2.5
compatible release on .NET 2.0 SP1. By far, the biggest change to 2.0 is
that our 1.1 codebase was refactored to run on top of the <a
href="http://www.codeplex.com/dlr">Dynamic Language Runtime</a>. With
this we automatically get improvements in many feature areas such as better
.NET interop support and hosting Python from managed code. There have
been many other major improvements as well. The most notable are:<o:p></o:p></p>

<p class=MsoNormal>This seems like an opportune time to remind everyone that we
fix bugs based on the number of votes they have on CodePlex. As
we’re planning on releasing IronPython 2.0.1 fairly soon, please vote for
your favorite bugs at <a
href="http://www.codeplex.com/IronPython/WorkItem/AdvancedList.aspx">http://www.codeplex.com/IronPython/WorkItem/AdvancedList.aspx</a>
to help ensure they get fixed in time for the next release.<o:p></o:p></p>
