I'm happy to announce that we finally have a release candidate for
SymPy 0.7.2.  Go to http://code.google.com/p/sympy/downloads/list to
see them.

Please test this, and make sure that everything works.  SymPy 0.7.2
adds support for Python 3, and we also have support for PyPy, assuming
you are running a recent nightly.   So please test this, make sure the
tarball includes everything it should (and nothing it shouldn't), that
it installs, etc.  If someone could test the windows installer in
particular, that would be great.

Also, I couldn't make a Windows installer for Python 3, because I got
this error:

Warning: Can't read registry to find the necessary compiler setting
Make sure that Python modules winreg, win32api or win32con are installed.
Traceback (most recent call last):
  File "./setup.py", line 286, in <module>
    classifiers = classifiers,
  File "/sw/lib/python3.3/distutils/core.py", line 148, in setup
    dist.run_commands()
  File "/sw/lib/python3.3/distutils/dist.py", line 917, in run_commands
    self.run_command(cmd)
  File "/sw/lib/python3.3/distutils/dist.py", line 936, in run_command
    cmd_obj.run()
  File "/sw/lib/python3.3/distutils/command/bdist_wininst.py", line 179, in run
    self.create_exe(arcname, fullname, self.bitmap)
  File "/sw/lib/python3.3/distutils/command/bdist_wininst.py", line
262, in create_exe
    cfgdata = cfgdata.encode("mbcs")
LookupError: unknown encoding: mbcs

meaning it has to be run in Windows to work.  So I may need someone to
help me out with that (unless I can get Python working on my Windows
machine).

I will let the release candidate sit for at least a week, and if there
are no major problems, I will do the full release.  I will announce
the release notes at that time.

In the meanwhile, we do need help writing the release notes still, so
if you made any major contributions to SymPy in the past year, please
make sure it is mentioned at
https://github.com/sympy/sympy/wiki/Release-Notes-for-0.7.2.
