<p class="MsoNormal">Hello Python Community,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We’re pleased to announce the release of
IronPython
2.6.1 RC1. This version of IronPython makes great strides in stability
and
compatibility, including a considerable number of targeted bugfixes.
Because
this is our largest servicing release to date, and due to our decision
against
incrementing the assembly version numbers, it is important that we get
everything right. To this end, we present our first-ever RC for a minor
dot
release. Of course, your feedback is imperative to the quality of this
release,
so we’d love to hear from you!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">IronPython 2.6.1 comes in two flavors – one that
runs
on top of .NET 4.0 RC, and one that runs on any other framework
starting with
.NET 2.0 SP1. They can be downloaded here:<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Note: The .NET Framework 4.0 RC is required for
the latter
release and can be downloaded at <a moz-do-not-send="true"

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">IronPython 2.6.1 RC1 includes fixes for well
over 50 bugs,
large and small. Ctypes has had a number of significant updates,
including
union support, variant_bool, and wintypes. Another focus has been on
sys.settrace, making debugging more reliable. For example, sys.settrace
now
returns the correct frame, supports tracing through modules, and no
longer
interferes with “import os”. Other notable fixes include thread-safe
importing, and the missing error code in _winreg exception.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In addition, we’ve made a substantial
improvement in
import time. Not only does this reduce startup time, but can speed up
the
importing of large, definition-heavy modules by up to 50%.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As you might imagine, the .NET 4.0 flavor of
IronPython
2.6.1 RC1 has a few of its own changes designed for better
interoperability
with the framework. These include fixing some errors with Func<>
and
better runtime isolation when similarly-named assemblies in different
locations
are loaded in multiple engines. In addition, both the .NET 2.0 and .NET
4.0
builds support the new .NET 4.0 IStructuralEquatable and
IStructuralComparable
interfaces and maps them to the appropriate operations (__eq__,
__hash__, __gt__,
etc.). In the case of .NET 4.0, this replaces IValueEquality as the
gold
standard for defining equality in an interop-friendly manner. In the
.NET 2.0
build, these interfaces are copied so that their use can be phased in
while
retaining IValueEquality for backwards compatibility.<o:p></o:p></p>
