We've just released the first beta of IronPython 1.0 and are entering the home stretch to a 1.0 final build. This build includes many bug fixes for issues reported to us by the community as well as many changes to get better compatibility with CPython 2.4. With this build we've addressed the majority of major design issues for a 1.0 final. We're not sure that you'll agree with all of our answers, so pick it up and let us know what you think.

You should expect to continue to see releases every 3 weeks for the near future. We're not going to commit to any fixed number of beta releases, but I can tell you that I'm a huge fan of single digit numbers and a beta 10 release would be unbelievably ugly to have to make. The major open design issues that we resolved for this release include: * Moved LoadAssembly* functions out of sys into new clr module See "Loading .NET libraries" in the shipped tutorial for more info * New exception system for better CPython compatibility AND CLI interoperability We've already sent email about this change and expect the discussion to continue now that you have real bits to play with * CLI methods are not exposed on Python types unless the accessing module uses "import clr" We owe you an email on this one in the next couple of days * Fixed many memory leaks when using eval/exec by using DynamicMethods This should make PythonEngine a much better script host We've also made some significant strides for cleanup of the release: * Updated the Avalon tutorial for the December CTP * Source code layout has been refactored * Fixed numerous PEVerification errors for generated code Finally, we're getting really strong on CPython compatibility: * From __future__ import division support * Support for -i command line option * More passing tests: test_warnings, test_opcodes, test_grammer, test_types We'd like to thank everyone in the community for your bug reports and suggestions that helped make this a better release: Andrew Pliszka, Edward K.
