We'll certainly be supporting 2.4 for quite a while. There is
currently not one single *nix distro (counting Apple OSX as one) that
defaults to Python 2.5, not even the fresh-off-the-oven Fedora Core 6
and Ubuntu Edgy Eft, both released in the last 72 hours. These still
use 2.4.x (x=3 for FC6 and x=4c1 for Edgy Eft, which I installed
And Ubuntu Dapper, bound to have a long life in research labs (due to
its long term support) uses 2.4, so for now we'll keep 2.4 as a
requirement. Right now, making code be 2.5-only would alienate a
pretty large fraction of ipython's user base, I suspect (including a
user I consider particularly important: me ;)

The chainsaw branch will eventually offer all of the normal ipython
functionality, including magic support. But hopefully we'll have a
much cleaner infrastructure in place to do so. Much of the code in
some of the bigger magics (%run and %edit are the worse) grew simply
by historical accretion, and is one big spaghetti mess in bad need of
And thanks for this release!
