IronPython 2.7.3 Beta 1
The next version of IronPython, 2.7.3, has reached the beta stage, and you can get it right here. There are no major new features since the last alpha, just a stack of small bug fixes. The only new feature is an implementation of PEP 421, which adds a new attribute to the sys module, sys.implementation, that contains information to consistently identify the current Python implementation.
The final release of 2.7.3 is targeted for July 1, so please test this release out and report any issues so that they can be fixed prior to that.
