I discovered a small bug in the documentation. When you visit the main
documentation page of Python 3.4, the menu says that Python 3.3 is
stable and that 3.5 is in development.
WHen you then click on 3.5, it says Python 3.4 is stable.
WHen you now return to 3.4 and then click on 3.3, it says that Python
3.4 is in development. It probably got left behind in updating
documentation, but this was kind of confusing for me.
