How widely adopted is python 2.5?

We are doing some development, and have a choice to make:
a) Use all the 2.5 features we want.
b) Maintain backwards compatability with 2.4.

So I guess the question is, does anyone have a sense of what percent
of python users don't have 2.5?

Thanks,
Joseph

I think it depends more on what you want to do. If you're distributing
the software, you can just "freeze" it and make binaries and then it
doesn't matter. Or if you use Python at your business, you can do what
we do at my workplace: Put Python on the network and run all the
scripts from there.

Currently, we have 2.4 on our network, but I think we can upgrade it
to 2.5 without breaking anything. I develop in 2.5 and just put the
finished products on our network and they usually "just work". But I
have yet to find good use cases for some of the cool whizz-bang extras
of 2.5, so I haven't pushed for the network upgrade.

I hope to figure out when, where and how to use generators and
decorators at some point, but I just haven't gotten that far a long
yet, I guess.

For server, you should probably rather look at distros like
RHEL/CentOS, Suse and Debian Stable.

For what it's worth, Fedora 8 has Python 2.5, RHEL 5 ships with
Python 2.4, and RHEL 4 has Python 2.3. Suse and Debian, I don't
know.

I would expect that to often depend on what OS version they are
using. And RHEL/CentOS 4 is still quite common, so if you want
to reach a large "customer base", make sure that your Python
programs work with Python 2.3.

Basically, we're planning on releasing it as open-source, and don't
want to alienate a large percentage of potential users.

Desktop or server?

If server, check what the major Linux distros, like Fedora
Core, are shipping with.

Check major shared hosting providers to see what they're offering
to their customers as standard.

Perhaps you should ask the inverse question too: what 2.5 features do
you find so compelling that you are willing to break compatibility
with 2.4 ? FWIW, the only new 2.5 feature I have been using in
practice is the conditional expressions, and I could easily live
without them. 2.4 is still pretty decent, and a major upgrade from
2.3.

Debian Etch (stable) has Python 2.4

One possible barometer for the situation is what's the oldest version
of Python to have been supported in the most bug-fix releases?

....In which case you need to maintain backwards compatibility with
2.3.

(I bring this up to illustrate that if there are people clamoring for
a 2.3 updates, there are probably quite a few supporting 2.4 as well.)

How about Java users? Jython was recently at 2.2 (still is for all I
know). I'm pleased they've got that far because I like to know that
my code can run under Java and I like generators.

My web host uses 1.5.2. That is painful.

If you're assuming your potential users already have 2.4 then the
chances are they'll have upgraded to 2.5 by the time you've finished
anyway.

99% is a big percent. My 1% doesn't like something.
