IronPython 1.1.2

[Dave Fugate]

Hello Python Community,

I'm pleased to announce the release of IronPython 1.1.2 which is our last planned 1.1 release.  Our 1.x releases in turn target compatibility with CPython 2.4.

IronPython v1.1.2 is a minor update in which we fixed the most requested CodePlex bugs and also a handful of trivial bugs.  In total twenty-one bugs have been resolved for 1.1.2.  It's worth noting that this included the implementation of the "_winreg" CPython module and a few performance improvements in targeted areas. Please also note that there are two potentially breaking changes in this release:
[PicExportError]  * nt.unlink will now throw an exception if the file doesn't exist, as it does in CPython
[PicExportError]  * The signature of IronPython.Runtime.Operations.Ops.Id() has changed and it now returns an object instead of long. This maps to the id() function in Python. Note that there is no change for Python caused by this and only code which is directly calling Ops.Id from a statically typed language like C# or VB will be affected.

The following CodePlex Work Items were closed:

* 16368 1.1.2: nt.access is missing

* 16402 1.1.2: implement _winreg module

* 15105 1.1.2: endpos is zero in IronPython 1.1.1
