[IronPython] IronPython 1.0 Beta 7 Released!

[Dino Viehland]

Hello IronPython Community,

We have just released IronPython 1.0 Beta 7. This release focuses primarily on fixing bugs and improving compatibility with CPython.  We’ve enabled a significant number of CPython regression tests that pass unmodified (test_bufio, test_colorsys, test_dircache, test_dummy_threading, test_filecmp, test_fileinput, test_fnmatch, test_fpformat, test_hexoct, test_htmllib, test_list, test_pkg, test_pkgimport, test_popen, test_popen2, test_sgmllib, test_textwrap, test_univnewlines, test_userstring).  We’ve also partially enabled many tests that pass w/ a few test cases disabled (those include test_bisect, test_decimal, test_decorators, test_iter, test_pow, test_repr, test_scope, test_sort, test_syntax).

Additionally with this release we’ve started strong name signing of IronPython.  If you’d like to build your own strong named version you’ll need to provide your own key and use the Signed Release or Signed Debug build configurations.

A more complete list of changes follows at the end.
