+- Issue #12776,#11839: call argparse type function (specified by add_argument)
+ only once. Before, the type function was called twice in the case where the

- error handling. Patch by Serhiy Storchaka.

+What's New in Python 3.3.0 Release Candidate 2?
+===============================================

- absolute imports are the default behavior in 3.0 instead of 2.7.
- Patch by Sven Marnach.
+*Release date: XX-Sep-2012*
-- Issue #14761: Fix potential leak on an error case in the import machinery.
+Core and Builtins

+ errno error numbers and Windows error numbers.
-- Issue #14433: Prevent msvcrt crash in interactive prompt when stdin
- is closed.
+- Issue #15781: Fix two small race conditions in import's module locking.
-- Issue #11603 (again): Setting __repr__ to __str__ now raises a RuntimeError
- when repr() or str() is called on such an object.
+Library
+-------
-- Issue #14658: Fix binding a special method to a builtin implementation of a
- special method with a different name.
+- Issue #15828: Restore support for C extensions in imp.load_module()
-- Issue #14630: Fix a memory access bug for instances of a subclass of int
- with value 0.
+- Issue #10650: Deprecate the watchexp parameter of the Decimal.quantize()
+ method.
-- Issue #14612: Fix jumping around with blocks by setting f_lineno.
+- Issue #15785: Modify window.get_wch() API of the curses module: return
+ a character for most keys, and an integer for special keys, instead of
+ always returning an integer. So it is now possible to distinguish special
+ keys like keypad keys.
-- Issue #14607: Fix keyword-only arguments which started with ``__``.
+- Issue #14223: Fix window.addch() of the curses module for special characters
+ like curses.ACS_HLINE: the Python function addch(int) and addch(bytes) is now
+ calling the C function waddch()/mvwaddch() (as it was done in Python 3.2),
+ instead of wadd_wch()/mvwadd_wch(). The Python function addch(str) is still
+ calling the C function wadd_wch()/mvwadd_wch() if the Python curses is linked
+ to libncursesw.
-- Issue #13889: Check and (if necessary) set FPU control word before calling
- any of the dtoa.c string <-> float conversion functions, on MSVC builds of

- while writing error message if the thread leaves a unhandled exception.
+- Issue #15814: The memoryview enhancements in 3.3.0 accidentally permitted
+ the hashing of multi-dimensional memorviews and memoryviews with multi-byte
+ item formats. The intended restrictions have now been documented - they
+ will be correctly enforced in 3.3.1
-- Issue #13019: Fix potential reference leaks in bytearray.extend(). Patch
- by Suman Saha.
-- Issue #14378: Fix compiling ast.ImportFrom nodes with a "__future__" string as
- the module name that was not interned.

- passed strings.
+Core and Builtins
+-----------------
-- Issue #1469629: Allow cycles through an object's __dict__ slot to be
- collected. (For example if ``x.__dict__ is x``).

+ support for any valid struct module format definition.
-- Issue #14172: Fix reference leak when marshalling a buffer-like object
- (other than a bytes object).
+- Issue #15316: When an item in the fromlist for __import__ doesn't exist,

+ let that propagate.
-- Issue #13521: dict.setdefault() now does only one lookup for the given key,
- making it "atomic" for many purposes. Patch by Filip Gruszczyński.

+ even when msg isn't a str.
-- Issue #14471: Fix a possible buffer overrun in the winreg module.

+ copied to the cached bytecode file. (The migration to importlib
+ reintroduced this problem because these was no regression test. A test
+ has been added as part of this patch)
