Hello,

We have just released IronPython 0.9.2. In addition to focusing on the
CPython regression test suite
and fixing bugs, we also spent time prepairing IronPython for PDC 2005
conference where Jim spent the
whole of the last week. There were many changes in IronPython codebase,
mostly inspired by getting
the regression tests running and adding CPython 2.4 features.

IronPython 0.9.2 can now run: test_math, test_unary, test_binop,
test_fnmatch, test_macpath, 
test_ntpath, test_operations, test_rfc822, test_urlparse, test_contains,
test_augassign, 
test_call and test_operator without any changes to the tests.

Two tests required modifications:
test_enumerate - disabled one line in the tuple reuse test
                 that relies on reference counting
test_long - part of the test requires closures and few testcases are
disabled
            for bugs. However, we run most of the tests successfully.

Thanks to all of you who reported bugs and provided feedback that
influenced this release:
Anthony Tarlano, Nicholas Jacobson, Erin Renshaw, Vargaz, Pelikhan, Mike
Stall,
Sdahlbac, Jan Kotas and Mike Hostetler.

The larger items in this release are:
- implementation of PEP 289: Generator Expressions
- implementation of PEP 318: Decorators for Functions and Methods
- integer arithmetics fixes that got test_long to work
- operator built-in module

The full list of bugs fixed can be found below.
