FWIW, RHEL 6.0 shipped with 2.6.5, and we rebased to 2.6.6 in RHEL 6.1:

FWIW, the previous version of Mac OS X (10.6) shipped with 2.6.1.

Sure, Jaunty was just an example. I'm not sure what versions of 2.6
are on different releases of RHEL, CentOS etc.

I would argue that Jaunty being a non-LTS release shouldn't be considered as a 
target platform we want to support. OTOH the LTS release Ubuntu Lucid (10.04) 
ships Python 2.6.5, so we're good.

In a similar vein, I'm actually still doing security fixes for Python
2.2 for some RHEL customers, and for 2.3 and 2.4 for RHEL 4 and 5 (we
never shipped 2.5 in RHEL; we're at 2.6.6 in RHEL 6)

(But I don't want to stand in the way of Python 3 support, and 2.6 is
probably the minimum sane version of 2.* to handle a dual 2/3 codebase)

Before we do this, another decision is required - which release of 2.6
is the minimum Django should support? There was a change which
occurred with 2.6.5 (IIRC) to allow Unicode in kwargs keys (earlier
versions would raise an exception).

If we use "from __future__ import unicode_literals" to avoid using u()
and b(), then a lot of Django code will be affected. Supporting 2.6-

While I agree it should be dropped, I was discussing this with the Twisted guys. They pointed out that it will actually receive security updates through 2013. This is thanks to Ubuntu 8.10 LTS. I'm sure Canonical could tap into someone like Barry to fix it if serious enough.-- Sent from my HP TouchPadOn Dec 11, 2011 11:31 PM, Paul McMillan  wrote: > 2.5 is EOL and no longer receiving security patches even, it is

This. +1 from me. We do everything else in our power to encourage

This is a very good reason I hadn't though of.

Re: Proposal: drop Python 2.5 support in Django 1.5

[Markus Gattol]

Wasn't the reason why Django 1.4 should still support Python 2.5 because of 
RHEL 5? If so, RHEL 5 never had official Python 2.5 support but only 
supported Python 2.4. RHEL 6 does not support 2.5 either, its Python 
version is 2.6. What is the reason that Django 1.4 needs to support Python 
2.5?

I think both of these proposals are great -- start merging the Python
3 work right after we release 1.4, and drop support for Python 2.5 in
trunk after 1.4 is released.

I think dropping Python 2.5 in the process of porting Django to Python 3.X are 
reasonable goals. That said, even without the Py3k work going so well I would 
support dropping Python 2.5 in the next major version.
