*** 17,25 ****

 There will be at least two alpha releases, two beta releases, and
! one release candidate. Other than that, no claims are made on
! release plans, nor what will actually be in Python 2.4 at this
! early date. There were 19 months between the Python 2.2 final and
! Python 2.3 final releases. If that schedule holds true for Python
! 2.4, you can expect it some time around February 2005.

 There will be at least two alpha releases, two beta releases, and

 - The import lock could use some redesign. (SF 683658.)

- - Set API issues; is the sets module perfect?
- 
- I expect it's good enough to stop polishing it until we've had
- more widespread user experience.
- 
 - A nicer API to open text files, replacing the ugly (in some
 people's eyes) "U" mode flag. There's a proposal out there to

- - Fredrik Lundh's basetime proposal:

- I believe this is dead now.
- 
 - PEP 304 (Controlling Generation of Bytecode Files by Montanaro)

 slow and the compiler is only the first step. Maybe we'll be
 able to refactor the compiler in this release. I'm tempted to

! a much simpler idea that may give a serious boost to the
! performance of accessing globals and built-ins, by optimizing
