Removing the Trove classifiers can be done with this shell script:

#!/bin/sh
# Remove Python 2.6 and 3.2 classifiers (and lower) from setup.py.
cat setup.py | grep -v 'Programming Language :: Python :: 2.3' | grep -v 
'Programming Language :: Python :: 2.4' | grep -v 'Programming Language 
:: Python :: 2.5' | grep -v 'Programming Language :: Python :: 2.6' | 
grep -v 'Programming Language :: Python :: 3.0' | grep -v 'Programming 
Language :: Python :: 3.1' | grep -v 'Programming Language :: Python :: 
3.2' > setup.py.tmp
mv setup.py.tmp setup.py
git diff setup.py
echo "Commit this? [ENTER means yes, anything else means revert] "
read answer
if test "x$answer" == 'x'; then
    echo "committing"
    git commit setup.py -m "Removed Python 2.6 and 3.2 classifiers (and 
lower)."
else
    echo "Reverting setup.py."
    git checkout -- setup.py
fi


I am looking if I can create a new command in zest.releaser to add a 
changelog entry that you pass on the command line.


Bumping versions: can be easily done with zest.releaser when doing a 
release.  But if you are not yet creating a release and only want to 
update the development version, this cannot be done yet.  I might be 
able to add that too.  Normally not too useful, but in batch it can be 
handy.
