Hi folks --

I wanted to fill everyone in on our plans for the Django 1.5 release.
The highlights are:

* Feature freeze October 1st, final out before Christmas.

* One marquee feature of Django 1.5 is experimental Python 3 support.
This is where we need your help the most: we need to be sure that our
support for Python 3 hasn't destabilized Django on Python 2. We need
lots of testing here!

* Most features of 1.5 have already landed, but we're also hoping to
land the new pluggable User model work, add support for PostGIS 2.0,
start the process of deprecating django.contrib.localflavor, and a few
other small things.

* This'll be our first "master never closes" release: work, including
new features, can continue to land on master while we ship the
release.

Please read on for details.

Timeline
--------

Oct 1: Feature freeze, Django 1.5 alpha.
Nov 1: Django 1.5 beta.
Nov 26: Django 1.5 RC 1
Dec 10: Django 1.5 RC 2
Dec 17: Django 1.5 RC 3, if needed
Dec 24 (or earlier): Django 1.5 final

(All dates are "week of" - we'll do the releases that week, though not
neccisarily that exact day.)

Notice the longer-than-usual timeline from beta to final. We're doing
this to provide some extra time stablizing the release after landing
the Python 3 work. Please see below for details and how you can help.

Python 3 support
----------------

Django 1.5 includes experimental support for Python 3 (it's already
landed on master). We're taking a "shared source" approach: Django's
code is written in a way that runs on both Python 2 and Python 3
(without needing 2to3's translation). This means that we've touched
nearly the entire codebase, and so the surface area for possible bugs
is huge.

WE REALLY NEED YOUR HELP testing out Django 1.5 *on Python 2*. Please
grab master, or one of the upcoming alpha/beta/RC releases, and test
it against your apps and sites. We need you to help us catch
regressions.

We're not yet recommending that people target Python 3 for deployment,
so our main focus here is ensuring that we're still rock-solid on
Python 2. If you *want* to give Python 3 a whirl things should be
pretty solid, but we *especially* need real-world reports of success
or failure on Python 2.

Features in 1.5
---------------

Besides the stuff that's already landed (see
https://docs.djangoproject.com/en/dev/releases/1.5/), there are a few
other features we're hoping to land:

* The "pluggable User model" work (Russell Keith-Magee).
* Some early low-level schema alteration plumbing work (Andrew Godwin).
* Moving django.contrib.localflavor out into individual external
packages (Adrian Holovaty).
* Support for PostGIS 2.0 (Justin Bronn).
* Python 3 support in GeoDjango (Aymeric Augustin).
* App-loading (Preston Holmes) is "on the bubble" - there's some
debate among the core team over whether its ready, but it's close.

Of course, as with our previous releases, the *real* list of what'll
go in 1.5 is "whatever's done by October 1st". If you want to help
with any of the above areas, contact the person doing the bulk of the
work (listed above) and ask to help. And if you have other features
you'd like to land, get 'em done!

Master never closes
-------------------

This'll mark our first release where "master never closes".

To recap: in previous releases, once we hit feature freeze we froze
the development trunk, forcing all feature work out to branches. In
practice, this meant months-long periods where new features couldn't
be merged, and led to some stuff withering on the vine.

That's not going to happen this time. Instead, when we release 1.5
alpha we'll make a 1.5 release branch right at that point. Work will
continue on master -- features, bugfixes, whatever -- and the
aplicable bugfixes will be cherry-picked out to the 1.5 release
branch.

The upshot is a bit more work for us committers -- we'll have to be
sure to merge the aplicable commits over -- but no more "sorry you
have to wait three months to merge this work." I'm very happy about
this!

[Committers: I'm happy to assist with this porting of bugfixes from
master to the release branch.]

See you on the other side, folks!

Jacob
