This made no sense whatsoever any more, so + now both __new__ and __init__ see all arguments. + - In 2.2a3, hash() applied to an instance of a subclass of str or unicode always returned 0.

Now it returns a str with the same value as s. +- Applications using Jim Fulton's ExtensionClass module can now safely + be used with Python 2.2. In particular, Zope 2.4.1 now works with + Python 2.2 (as well as with Python 2.1.1). The Demo/metaclass + examples also work again. + +- Thread scheduling on Solaris should be improved; it is no longer + necessary to insert a small sleep at the start of a thread in order + to let other runnable threads be scheduled. + Library +- SimpleXMLRPCServer: a new module (based upon SimpleHTMLServer) + simplifies writing XML RPC servers. + +- os.path.realpath(): a new function that returns the absoute pathname + after interpretation of symbolic links.

On Linux, at + least, it's possible to have a system whose C library supports large + files but whose kernel doesn't; in this case, large file support is + still enabled but doesn't do you any good unless you upgrade your + kernel or share your Python executable with another system whose + kernel has large file support. + +- The configure script now supplies plausible defaults in a + cross-compilation environment. This doesn't mean that the supplied + values are always correct, or that cross-compilation now works + flawlessly -- but it's a first step (and it shuts up most of + autoconf's warnings about AC_TRY_RUN). + +- The Unix build is now a bit less chatty, courtesy of the parser + generator.
