On behalf of the IronPython team, I'm happy to announce the first (and
probably only) release candidate for IronPython 2.7.2. Only
showstopping bugs will be fixed before the release.

You can download IronPython 2.7.2 RC from

Like all IronPython 2.7-series releases, .NET 4 is required to install
it. Installing this release will replace any existing IronPython
2.7-series installation.

Unlike previous releases, the assemblies for all supported platforms
are included in the installer as well as the zip package. IronPython
2.7.2 RC includes support for .NET 3.5, .NET 4, Silverlight 4,
Silverlight 5, Mono for Android 4.0, and Windows Phone 7.5. Check the
"Platforms" directory for the required assemblies. Any feedback on the
supported platforms, especially for Android and Windows Phone, is
greatly appreciated. For 2.7.2, the mobile platforms should be treated
as previews, and expect them to change for 2.7.3.

The biggest improvements in IronPython 2.7.2 are support for the
zipimport module, thanks to Alex Earl, and the sqlite3 module. The
pyc.py compiler can now generate standalone executables by embedding
the IronPython assemblies. Many other bugs have been fixed as well.

IronPython 2.7.2 RC 1 is also available on NuGet. To add it to your
project, run Install-Package IronPython -IncludePrerelease (and
Install-Package IronPython.StdLib -IncludePrerelease if you want the
standard library as well) from the Package Manager Console. Because
it's a prerelease package, it won't show up in the Package Manager UI.

The final release of IronPython 2.7.2 is currently set for March 11.
