Bug report

There is no version information on the documentation pages.

Details

If you google code samples of matplotlib, you will get links to different versions of the matplotlib documentation. On these documentation pages, there is no hint, which version of matplotlib you are looking at. Even the URL of the documentation doesn't give a clue! If you try some code (official samples from the official documentation!), you may wonder why it is not working in your installation of matplotlib.

Why this matters

Especially for beginners, this is very frustrating! You may try to figure out whats wrong for hours and post questions on stackoverlow, just to find out, that the matplotlib documentation doesn't care to show a clue which version you are looking at (as happened to me examples/showcase/xkcd.py)!
