- 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
- return a bool instead. Read PEP 285 for an explanantion of why this
+ return a bool instead. Read PEP 285 for an explanation of why this
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.
-- posix.killpg has been added where available.
-
-- sys.exit() inadvertantly allowed more than one argument.
+- sys.exit() inadvertently allowed more than one argument.
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.
-- posix.mknod was added.
+- posix.killpg and posix.mknod have been added where available.
- The locale module now exposes the C library's gettext interface.
- compileall now supports quiet operation.
-- The BaseHTTPServer implements now optionally HTTP/1.1 persistent
+- The BaseHTTPServer now implements optional HTTP/1.1 persistent
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.
-- The "u#" parser marker will now pass through Unicode object as-is
+- The "u#" parser marker will now pass through Unicode objects as-is
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
- need a TemproraryFileWrapper wrapper anymore, and should be immune
+ need a TemporaryFileWrapper wrapper anymore, and should be immune
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
- when run from the standard regresssion test.
+ when run from the standard regression test.
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
- using new-style MRO rules if any base clase is a new-style class.

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
- uniform way because the mmap() signuatures had diverged across
+ uniform way because the mmap() signatures had diverged across
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.
- These map to readonly attributes 'fget', 'fset', 'fdel', and '__doc__'
+ These map to read-only attributes '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
- a str sublass type, s[:] returned s as-is. Now it returns a str
+ a str subclass type, s[:] returned s as-is. Now it returns a str
with the same value as s.
- Provisional support for pickling new-style objects has been added.
