<p class=MsoNormal><span style='color:black'>Hello Python Community,<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:black'>We’re proud to announce the
release of IronPython 2.6 final. This is a major release with
improvements across all areas of IronPython and can be downloaded from <a
href="http://ironpython.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=12482">http://ironpython.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=12482</a>.

improvements<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:black'>Python 2.6 support includes a
large number of new features which include support for the new bytes and byte
array types (<a href="http://www.python.org/dev/peps/pep-3112/" target="_blank">PEP
3112</a>), decorators for classes (<a
href="http://www.python.org/dev/peps/pep-3129/" target="_blank">PEP 3129</a>),
advanced string formatting (<a href="http://www.python.org/dev/peps/pep-3101/"
target="_blank">PEP 3101</a>) which will feel familiar to .NET users and
integrates nicely with IFormattable, print as a function (<a
href="http://www.python.org/dev/peps/pep-3105/" target="_blank">PEP 3105</a>),
Abstract Base Classes (<a href="http://www.python.org/dev/peps/pep-3119/"
target="_blank">PEP 3119</a>), support for binary literals, along with lots of
other minor features and changes.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:black'>IronPython also continues to
improve .NET integration in this release. We’ve added the <a
href="http://ironpython.net/ironpython/documentation/dotnet/dotnet.html#clrtype"
target="_blank">__clrtype__ method</a> to types which enables deep integration
via meta-classes with the .NET type system. There are also a number of
smaller changes such as supporting <a
href="http://ironpython.codeplex.com/WorkItem/View.aspx?WorkItemId=24503"
target="_blank">IDisposable in for loops</a> matching the behavior of other
.NET languages. This release also includes the latest version of the DLR
and fixes a number of issues related to cross-language dynamic interop.
Not to be left out there’s improvements in Silverlight integration by
supporting <a href="http://ironpython.net/browser/sl-back-to-just-text.pdf"
target="_blank">Python code in HTML script tags</a>.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:black'>We’ve also continued to
improve Python compatibility by adding missing features and fixing bugs.
In this release we’ve added support for the <a
href="http://docs.python.org/library/ctypes.html" target="_blank">ctypes</a>
module which provides interop with native code in a compatible way across
Python implementations. We’ve also implemented sys.settrace to
provide support for the <a href="http://docs.python.org/library/pdb.html"
target="_blank">pdb</a> module and other Python debuggers. This release
also changes how we support sys._getframe: a fully working version is now
available by a command line option; when not enabled sys._getframe
doesn’t exist at all. This release also fixes over 400 bugs removing a
large number of smaller incompatibilities.<o:p></o:p></span></p>
<p class=MsoNormal><span style='color:black'>As always we’ve also
continued to improve performance, and this release primarily focuses on
improving startup time. The IronPython installer now pre-compiles (ngens)
IronPython during installation on both 32-bit and 64-bit platforms.
Modules are now interpreted initially and hot functions are compiled for faster
import times. A number of other code paths that used to involve runtime code
generation have been optimized to be contained within the pre-compiled
IronPython binaries. We’ve also made a number of smaller changes
which improve performance in other areas such as adding constant folding. <o:p></o:p></span></p>
<p class=MsoNormal><span style='color:black'>Finally we’d like to thank
