Hello IronPython Community,

I’m pleased to announce the release of IronPython 1.1.1 Release Candidate 1. For this release we fixed the most requested CodePlex bugs and also a handful of trivial bugs. In total around twenty bugs have been resolved for 1.1.1 RC1. Additionally, an issue that was reported directly on the IronPython mailing list was fixed - testComparingClrObjects (see for details). Assuming no major issues are discovered in this build, we hope to rerelease it as IronPython 1.1.1 in a couple of weeks. Please let us know if you encounter any issues as soon as possible.

We'd like to thank everyone in the community for your bug reports and suggestions that helped make this a better release: Seo Sanghyeon. Pobrien, Giles Thomas, sdahlbac, grizlupo, Tony Djordjevski, ayarrow, Michael Foord, milind, Kristof Wagemans, and Jan Szumiec.
