Yes, next version of IPython is closing in on final release around the years end, with lots of new exiting features (full list TBD, but it *does* include proper python 2.5 support if that's what you've been waiting for).
Get the 0.7.3 beta 2 it at http://projects.scipy.org/ipython/ipython/wiki/Release/0.7.3 And remember to run %upgrade if you are already using an older version. -- http://mail.python.org/mailman/listinfo/python-list
