Upgrading from 2.5 to 2.6

That isn't entirely true. In Windows, python files bound to a
particular version of python in the registry. So, for example, if you
double click on "some_prog.py" to run it, then it will by default
start up using python2.6 once it is installed. Also right-clicking on
a file and selecting "edit with Idle" will open the version of Idle
associated with 2.6 (under 2.6). This is a minor difference, but I
wouldn't say that there are no side effects. They can be easily worked
around.
