Hello IronPython Community, We have just released
IronPython 1.0 Beta 6. This release focuses primarily on fixing bugs and
improving compatibility with CPython. Major cleanups includes supporting
__metaclass__ at the module level, using __mro__ for new-style class method
resolution, and a massive cleanup to make sure all of our comparisons are
identical to CPython. With this release we’ve also improved the
performance of calls to arbitrary .NET assemblies by enabling our
call-optimization for all assemblies and updated the tutorial for beta 6. One change that has the
potential to break people in beta 6 is that we are deprecating clr.Path and
instead suggesting everyone switch over to using sys.path instead. This
is more inline with how CPython searches for .pyd extension files and we
believe will simplify the loading story. This also means that the current
working directory will be included in the search path by default which seems to
have been an issue that caused many problems. In this release of
IronPython we’ve introduced a breaking change concerning the treatment of
.NET value types. We’d like to elicit your feedback on this change to
determine if it needs tweaking or outright changes prior to a V1.0
release. You can read more about this specific change at http://channel9.msdn.com/wiki/default.aspx/IronPython.ValueTypes
A more complete list of
changes follows at the end. You can download the release
from: http://www.microsoft.com/downloads/details.aspx?FamilyId=F5BB7DEF-7C71-40D0-9AD7-81E60E85E3DB&displaylang=en We'd like to thank everyone
in the community for your bug reports and suggestions that helped make this a
better release: Andrzej Krzywda, Erin Renshaw, Thanks and keep in touch, The IronPython Team More complete list of
