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 http://lists.ironpython.com/htdig.cgi/users-ironpython.com/2008-January/006171.html
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.
