<p class=MsoNormal><span style='color:black'>We’re pleased to announce
the release of IronPython 2.0 Beta 2. In addition to the usual bug fixes
(~25 reported on CodePlex and ~50 reported internally), this release has been
partially focused on improving the performance of IronPython, in particular
startup perf. Another focus of this release was improving upon our
traceback support which had regressed quite a bit in 2.0B1 and had largely been
broken in the 2.0 Alphas. Our traceback support should now be superior to
that of IronPython 1.1!<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:black'>We’ve also made a minor
change to our packaging by adding a Microsoft.Scripting.Core.dll in addition to
the Microsoft.Scripting.dll that’s been around since the start of
2.0. We are doing this purely as an architectural layering cleanup.
Microsoft.Scripting.Core contains DLR features that are essential to building
dynamic languages. Microsoft.Scripting will contain language
implementation helpers that can either be re-used (e.g., BigInts) or copied
(possibly e.g., the default binder). This process is all about our work
to get the DLR architecture right and shouldn’t have any noticeable
IronPython impact except that there’s now one more DLL to include in any
package.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:black'>As a consequence of the new DLL,
the deprecated file IronPython2005.sln is broken. This is the last
release that will include this .sln file in the source zip file. Of
course the Visual Studio 2008 version of this file, IronPython.sln, still
builds.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:black'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:black'>We’d like to thank everyone
in the community who reported bugs on CodePlex that were fixed in this release:
kevgu, oldman, christmas, brucec, scottw, fuzzyman, haibo, Seo Sanghyeon,
grizlupo, J. Merrill, perhaps, antont, 05031972, Jason Ferrara, Matt Beckius,
and Davy Mitchell.<o:p></o:p></span></p>
