Congratulations, guys! We'll build Resolver One against it and let you
know what breaks :-)

Hello IronPython Community,
I'm pleased to announce IronPython 2.0 *Beta 3*. We have fixed around
34 bugs in this release (~16 of them reported on Codeplex and ~18
reported internally). Apart from the bug fixes, this release contains
the following improvements:
· We have worked on perf -- specifically generators, exception
handling, and shootout perf have improved. We are aware of some
late-breaking degrades which we expect to fix by the next release.
· An auto-templating feature has been added to the Dynamic
Language Runtime which should improve performance in highly dynamic
scenarios.
· cmath and _winreg modules have been implemented.
There is a change in packaging this time. The Dynamic Silverlight
sources and binaries, compatible with Silverlight 2 Beta 2, are now
included in this release. This makes the package a single place to get
both the desktop and Silverlight versions of IronPython. The Visual
Studio solution file (IronPython.sln) has been updated to build under
"Silverlight Release" and "Silverlight Debug" configurations as well.
Please note that this requires Silverlight 2 Beta 2 to build properly.
IronPython2005.sln is no longer part of the package as was mentioned
in the last beta release notes. This means that Visual Studio
2008/.NET 3.5 is required to build IronPython.sln. Ofcourse
/toolsversion:2.0 flag can still be passed to msbuild and hence
IronPython can be built to run against .NET 2.0 runtime as well.
The following codeplex workitems have been closed since IronPython 2.0
Beta 2:
· nt.access is missing Closed Issue Medium Jun 2 at 7:24 PM
· Trivial: throw WindowsError (with 'errno' of 17) when
nt.mkdir called on pre-existing directory
· '_' is in the result of dir() after first expression evaluation
· -X:MTA option not supported by IP 2.0A
· expresion-1 if condition else expresion-2 working incorrectly
· Python Parser class is internal
· PythonType.HasGetAttribute property does not detect
inherited implementation.
· _winreg is not implemented
· SyntaxError(...).__dict__ is not a dict
· Using 'with' statment with IDisposable .NET type doesn't work
· IronPython forces objects in sys.meta_path to be new-style
classes
· imp.load_module("os", ...) broken
· DUPLICATE: Run ipyw .exe ( Iron Python 2 Beta 2 )
· REJECTED: Can't create & return nested function from
CreateDelegate
· id returns Int64 not int or long
· Overriding properties has strange syntax
We'd like to thank everyone in the community who reported these bugs:
py_sunil, jhardy, awilkins, oldman, and 05031972, Ronnie Maor,
Jonathan Amsterdam, sanxiyn, jackeyoo, Thane Plummer, Vizcayno
Tamparantan, Michael Foord, Alex Henderson
We've also closed these bugs that were reported internally:
· Trivial: Exception messages are not directed to
sys.stderr
· Python25: new exception hierarchy
· when base class provide over one ctor function,IronPython
can not distinguish them just like Cpython do.
· AttributeError: 'file' object has no attribute 'truncate'
· ImportError: No module named xxsubtype
· cmath module isn't implemented (complex arithmetic)
· long("0X20",16) throws ValueError: invalid integer number
literal
· ImportError: No module named _winreg
· dir(*()) returns something unexpected
· "print a_super_object" throws TypeError
· old style class constructed with an unpacked tuple
containing a single None barfs
· DLR crashes with stack overflow when ironpython.dll is missing
· Enable turning whole object models dynamic in IronPython
· Trivial: There is no "_md5" module in IronPython2.0 when run
the file of test_hmac.py
· TypeError: don't know how to disassemble code
objects
· sys.meta_path is not implemented
· calling setattr got an error .
· issubclass(Exception,object) return different result against
Ironpython and Cpython

IMPORTANT NOTES
ToyScript, a small scripting language built on top of the DLR, is
merely a DLR sample and not some new scripting language Microsoft has
created. Also, ToyScript is not intended to be distributed with
IronPython on a permanent basis.
