Hi Adam,
 
About "intellisense is not a major blocker for iron python adoption".
 
Unfortunately I think it might be.  The commercial world is all about
productivity.  I did a survey at work about replacing a well-known
development environment with eclipse and the result was "our only real
requirement is intellisense".
 
Cheers,
Kyle

I think the fact that there are more users for "Assembly for Web Pages"
and "AJAX on ALGOL" than IronPython for ASP.Net contributes to the delay
in updates. It's too bad for us that got addicted to the elegance of the
solution in the first place. I remember a couple of months ago about
updated support for intellisense in IP for ASP.Net, etc. Those are nice
to have but I think an updated IP would be enough to make everybody
involved ecstatic. I got a feeling intellisense is not a major blocker
for iron python adoption.

	Any update on the timeline for getting IronPython for ASP.Net
updated? This would make a world of difference for our IronPython-based
web app.

	This is awesome. Web application can benefit from this "adaptive
compilation" approach a lot - especially for low trafficked sites.

	Dave,
	
	This is great news, congratulations to the IP team on this
release! We'll do a test-port of Resolver One early next week and will
reply to the list with any issues we find.

	Hello Python Community,
	
	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.
	
	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:
	
	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
	
	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
	
	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
	
	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.
	
	There's also a few minor changes since IronPython 2.0.1 that are
worth calling out here:
	
	* IronPython.msi now installs NGEN'ed binaries by default
	
	* IronPython.msi now offers a little more selection with respect
to what you'd like to install. For example, Silverlight templates are
optional
	
	* 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
	
	* The -X:PreferComInteropAssembly flag has been removed. All COM
interop is now done through normal COM dispatch
