Hello Python Community,
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!
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:
- IronPython 2.6.1 RC1 for .NET 2.0 SP1:
http://ironpython.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=40144
- IronPython 2.6.1 RC1 for .NET 4.0 RC:
http://ironpython.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=40146
Note: The .NET Framework 4.0 RC is required for the latter release and
can be downloaded at

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.
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%.
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.
