How about the following:
1) Cut a new v1.0.x release, update the documentation at the
sourceforge site, and announce on all the mailing lists that
development has moved to github.
2) Announce that the v1.1.x series will be the last to support
<=python-2.5, and that a v1.1.x feature freeze is about to go into
effect. Once devs have the features committed that they will need with
<=python-2.5, create the v1.1.x maintenance branch and cut the 1.1.0
release.
3) Merge matplotlib-py3/master into matplotlib/master, champagne and doughnuts
4?) Make v1.2.0alpha1 binaries available so bleeding edgers can help
identify issues on Windows (and maybe OS X).

Hello,
Dateutil 2.0 is now available for Python 3.x at 
<http://niemeyer.net/python-dateutil>.
The example user_interfaces/mathtext_wx.py is broken since as_rgba_str() 
was removed from the ft2font extension. A patch is attached.

Things are looking pretty good over on the Python 3 branch, thanks to 
the great work done at CTPUG, Sage Days 29 and elsewhere, and it 
probably bears some discussion about where we'd like to go from here.
I'm thinking we should probably do another 1.0.x release with all of the 
bugfixes we currently have on that branch.
Then, the question is when to start treating the py3 branch as master. 
The only downside on Python 2.x (that I'm aware of) is the dropped 
support for Python < 2.6. There are still a number of reasons (mainly 
due to external library dependencies) that one may not to run matplotlib 
on Python 3.x, but that's a separate question, IMHO.
The status of the Py3 work is here:
https://github.com/matplotlib/matplotlib-py3/wiki
I would love a Mac user to build and run regression tests on both Python 
2.x and Python 3.x, and run some interactive examples, particularly the 
mac os backend, as I haven't been able to test that personally.
Thoughts?
Mike

It looks like the changes I made to fetch sample data from github
instead of sourceforge are causing problems if python was not compiled
with SSL support. Comment out ViewVCCachedServer in cbook.py and I'll
figure something out.

Hi all,
I am using the latest matplotlib.
How can I resolve the following problem ?
>>> import matplotlib
Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 File 
"/data/home/nwagner/local/lib/python2.5/site-packages/matplotlib/__init__.py", 
line 133, in <module>
 from matplotlib.rcsetup import (defaultParams,
 File 
"/data/home/nwagner/local/lib/python2.5/site-packages/matplotlib/rcsetup.py", 
line 19, in <module>
 from matplotlib.colors import is_color_like
 File 
"/data/home/nwagner/local/lib/python2.5/site-packages/matplotlib/colors.py", 
line 54, in <module>
 import matplotlib.cbook as cbook
 File 
"/data/home/nwagner/local/lib/python2.5/site-packages/matplotlib/cbook.py", 
line 453, in <module>
 class ViewVCCachedServer(urllib2.HTTPSHandler):
AttributeError: 'module' object has no attribute 
'HTTPSHandler'
 
Thanks in advance
 Nils
