This is great news, congratulations to the IP team on this release! We'll do a

<p class=MsoNormal style='margin-bottom:12.0pt'>Hello Python Community,<br>
<br>
We’re pleased to announce the release of IronPython 2.6 Alpha 1. As you might
imagine, this release is all about supporting new CPython 2.6 features such as
the ‘bytes’ and ‘bytearray’ types (PEP 3112), decorators for classes (PEP
3129), advanced string formatting (PEP 3101), etc. The minimum .NET version
required for this release is the same as IronPython 2.0; namely .NET 2.0
Service Pack 1. Unlike the 2.0 series of IronPython, we plan to release only a
couple Alphas and Betas of IronPython 2.6. As such, it’s key that we get your
feedback on the release(s) quickly to incorporate requested changes.<br>
<br>
Besides CPython 2.6 features, another significant change in this release is
that ipy.exe now uses “adaptive compilation” by default. Adaptive compilation
is a technique in which IronPython:<br>
<br>
1. Interprets and executes Python method calls up to /N/ times for a given
method. If you’re only going to execute a method a few times, it’s typically
faster to interpret the method instead of compiling and executing it<br>
<br>
2. Compiles and executes the Python method call on the /N+1/ invocation of the
method. Compilation of a Python method is a heavyweight operation, but we can
reuse the result for subsequent invocations<br>
<br>
3. Reuses the previously compiled method for new calls to the Python method.
This operation is much faster than interpreting the method call as the method
was already compiled in the previous step<br>
<br>
The reason for this change is that it provides a nice performance gain for
Python code containing lots of functions/methods that only get called a few
times. All this said, this feature is still undergoing active development and
as a consequence some Python scripts may actually run slower with it turned on.
For this reason, our old default mode of running Python scripts is still
available by passing the –O or -D flags to ipy.exe. Any feedback on how this
new feature affects your IronPython applications performance-wise would be
greatly appreciated.<br>
<br>
There’s also a few minor changes since IronPython 2.0.1 that are worth calling
out here:<br>
<br>
· IronPython.msi now installs NGEN’ed binaries by default<br>
<br>
· IronPython.msi now offers a little more selection with respect to what you’d
like to install. For example, Silverlight templates are optional<br>
<br>
· The default installation location of IronPython.msi no longer indicates
whether the 2.6 release is an Alpha, Beta, or a patched release. Future
IronPython 2.6 installations will replace previous 2.6 releases which will be
uninstalled automatically<br>
<br>
· The -X:PreferComInteropAssembly flag has been removed. All COM interop is now
done through normal COM dispatch<br>
