(Back to Python3000.)

General

The tasks to do are now kept in the tracker: bugs.python.org

Finding and removing all the cruft in the code and docs that has been deprecated. If you know of any of these things, please add a note to the wiki. Some common strings to look for are: deprecated, compatibility, b/w, backward, and obsolete.
- PyErr_Warn (Skip Montanaro, done)
- remove old patform support (Skip Montanaro, RISCOS/os.extsep, BeOS is done)
- remove PyArg_Parse, METH_OLDARGS (Skip Montanaro)
Py3kDeprecated

Coding

Finish bytes implementations (what's left to do?)
Add more set behavior to dict.keys(), .items(), .view() (PEP 3106)
- Consider defining dict as a subclass of set, then the most useful behavior is automatic (namely, set operations on keys.).
Library reorganization (PEP 3108, Brett Cannon) (make separate section?)
Py3kStrUniTests - fix the remaining 3-4 tests that are failing
Implement PEP 3101 - format() method (Talin, in sandbox/pep3101)
PEP 3109 - exceptions (Collin Winter)
Clean up io.py - new I/O (PEP 3116)
Write a Windows version of _fileio.c
Write accelerators for StringIO/BytesIO & pickling (Alessandre Vassolotti)
Implement PEP 3118 - new buffer API (Travis Oliphant, in py3k-buffer branch)
Implement PEP 3121 - Extension Module Initialization and Finalization (Martin von Loewis)
Implement PEP 3134 - exception chaining (Collin Winter?)
Implement PEP 3141 - numerical ABCs
Kill *slice APIs (Thomas Wouters will merge the noslice branch)
Optimize integers
Optimize strings
Whatever isn't yet listed *done* in PEP 3100
- unify __builtins__ vs __builtin__ or otherwise keep only one
- get rid of unoptimized functions
- cleanup various C APIs
- add support for trunc() and __trunc__
- move compile()?
What else?
