- A new built-in type, bool, has been added, as well as built-in

names for its two values, True and False. Comparisons and sundry

other operations that return a truth value have been changed to

is backward compatible.

- Fixed two bugs reported as SF #535905: under certain conditions,

Previously, an xreadlines object was returned which would raise

a ValueError when the xreadlines.next() method was called.

An exception will now be raised if more than one argument is used.

Extension modules

This will create a temporary in-memory bsddb that won't be

written to disk.

- The locale module now exposes the C library's gettext interface.

- compileall now supports quiet operation.

connections.

- socket module: the SSL support was broken out of the main

PyMem_MALLOC and PyMem_FREE, even if pymalloc is enabled. The

PyCore_* family of APIs have been removed.

without going through the buffer API.

- The enumerators of cmp_op have been renamed to use the prefix PyCmp_.

Windows (not the same thing as a Windows process id).

- New tempfile.TemporaryFile implementation for Windows: this doesn't

to a nasty problem: before 2.3, if you got a temp file on Windows, it

got wrapped in an object whose close() method first closed the

underlying file, then deleted the file. This usually worked fine.

- xmlrpclib.py: version 1.0.0; uses precision for doubles.

- test suite: the pickle and cPickle tests were not executing any code

Tools/Demos

The MRO (method resolution order) for each base class is respected

according to its kind, but the MRO for the derived class is computed

This needs to be documented.

- The new builtin dictionary() constructor, and dictionary type, have

both Windows and Unix users to create read-only, write-through and

copy-on-write memory mappings. This was previously possible only on

Unix. A new keyword argument was required to support this in a

platforms. Thanks to Jay T Miller for repairing this!

- By default, the gc.garbage list now contains only those instances in

report on SourceForge.)

- property() now takes 4 keyword arguments: fget, fset, fdel and doc.

in the constructed property object. fget, fset and fdel weren't

discoverable from Python in 2.2a3. __doc__ is new, and allows to

associate a docstring with a property.

where the subtype didn't override the operation (and so the

operation was handled by the builtin type), could return that

instance instead a value of the base type. For example, if s was of

with the same value as s.

- Provisional support for pickling new-style objects has been added.
