Add some news for 2.1b2. I'd still like someone else to add news
about these packages:
- distutils
- xml

Complex repr() now uses full precision + like float repr(). + +- sgmllib.py now calls handle_decl() for simple <!...> declarations. + Standard library -- A new module Tix was added, which wraps the Tix extension library for Tk. - With that module, it is not necessary to statically link Tix with _tkinter, - since Tix will be loaded with Tcl's "package require" command. +- unittest.py, a unit testing framework by Steve Purcell (PyUNIT, + inspired by JUnit), is now part of the standard library. You now + have a choice of two testing frameworks: unittest requires you to + write testcases as separate code, doctest gathers them from + docstrings. Both approaches have their advantages and + disadvantages. + +- A new module Tix was added, which wraps the Tix extension library + for Tk. With that module, it is not necessary to statically link + Tix with _tkinter, since Tix will be loaded with Tcl's "package + require" command. See Demo/tix/. + +- tzparse.py is now obsolete. + +- In gzip.py, the seek() and tell() methods are removed -- they were + non-functional anyway, and it's better if callers can test for their + existence with hasattr(). + +Python/C API + +- PyDict_Next(): it is now safe to call PyDict_SetItem() with a key + that's already in the dictionary during a PyDict_Next() iteration. + This used to fail occasionally when a dictionary resize operation + could be triggered that would rehash all the keys. All other + modifications to the dictionary are still off-limits during a + PyDict_Next() iteration! + +- New extended APIs related to passing compiler variables around. + +- New abstract APIs PyObject_IsInstance(), PyObject_IsSubclass() + implement isinstance() and issubclass(). + +- Py_BuildValue() now has a "D" conversion to create a Python complex + number from a Py_complex C value.
