Since there’s an MSI now, could we hope for updates/new-major-versions via 
Windows Update?  Like online banking, I’ve come to rely on things updating 
themselves, rather than having to keep track of various support download sites. 
 Not to be exclusive – I would expect downloads at CodePlex to remain available 
-- but for the ease of installation and maintainance, it’s hard to beat 
built-in, unified updaters.

 

If side-by-side versioning is required, I could see a current-version 
environment variable that could be added to the path.

Subject: [IronPython] Announcing IronPython 2.0

 

Hello Python Community,

 

The IronPython and Dynamic Language Runtime teams are proud to announce the 
release of IronPython 2.0 final.  IronPython 2.0 is the culmination of nearly 
two years worth of work resulting in a CPython 2.5 compatible release on .NET 
2.0 SP1.  By far, the biggest change to 2.0 is that our 1.1 codebase was 
refactored to run on top of the Dynamic Language Runtime 
<http://www.codeplex.com/dlr> .  With this we automatically get improvements in 
many feature areas such as better .NET interop support and hosting Python from 
managed code.  There have been many other major improvements as well.  The most 
notable are:

·         An MSI installer for Windows platforms which includes parts of the 
CPython 2.5 standard library

·         IronPython assemblies targeting Silverlight and tools such as Chiron 
to improve the Silverlight dynamic development experience

·         The addition of more C-based standard modules such as cmath and 
_winreg

·         Significant improvements in importing compatibility and features

·         Distribution of IronPython under the Microsoft Public License which 
has been approved by OSI

·         Performance improvements.  On that note, a new Wiki page has been 
created for IronPython performance reports - see 
http://www.codeplex.com/IronPython/Wiki/View.aspx?title=IronPython%20Performance

·         Over 500 bugs have been closed in 2.0.  453 of these were reported on 
CodePlex

·         Support for precompilation of Python source files into a single dll

 

This seems like an opportune time to remind everyone that we fix bugs based on 
the number of votes they have on CodePlex.  As we’re planning on releasing 
IronPython 2.0.1 fairly soon, please vote for your favorite bugs at 
http://www.codeplex.com/IronPython/WorkItem/AdvancedList.aspx to help ensure 
they get fixed in time for the next release.

 

We’d like to extend our gratitude to everyone in the IronPython community who 
reported bugs thereby making this a better release:  milind, romank,
