Many congratulations to the IP team on this release!
We should be able to start the process of properly porting Resolver One
to IP 2.0 RC1 in a week or so (we're just finishing off a release of our
own), but we've been tracking the betas up until now (as you might have
noticed from Michael Foord's emails), so we don't expect any major
issues. Of course, if anything does break you'll be the first to know :-)
Regards,
Giles

Hello IronPython Community,
We're pleased to announce the release of IronPython 2.0 Release
Candidate 1. We have fixed around 40 bugs since the previous beta.
There have been more than 500 bug fixes since the first 2.0 alpha was
announced. Apart from the bug fixes these items have also been addressed:
- The problem caused by ExtensionAttribute while using
IronPython in a .NET 3.5 project that references System.Core has been
fixed by moving that type to a new assembly called
Microsoft.Scripting.ExtensionAttribute.dll. If you are referencing
System.Core you should not reference this assembly while building it
but while deploying your application, this assembly needs to be
deployed as well. Harry has more details here
<http://devhawk.net/2008/10/21/The+Fifth+Assembly.aspx>.
- The MSI installer now has an option to ngen the installed
binaries. Ngen'ing the dlls gives a significant startup performance
boost. The option is turned off by default but if no issues are
reported, we'll enable it by default in a future release.
- The CPython standard library modules and packages that
cannot be imported in IronPython currently have been removed from the
MSI installation. The complete list is here
<http://www.codeplex.com/IronPython/Wiki/View.aspx?title=List%20of%20Standard%20Library%20components%20not%20included%20in%20the%20MSI>
- The DLR sample language ToyScript is included in this
release in a separate zip file. This is a temporary arrangement till
the sample finds a more permanent home. For the references in the
ToyScript project to line up, unzip it to the Src folder of the
IronPython source release.
If no major issues with the RC are reported, we hope to ship the final
2.0 release in around a month's time. *Anyone planning to move to 2.0
please try the RC and let us know of any issues you find.*
