Description:
Not possible to switch to other documentation versions with left hand side content table menu.

How to repeat:
Go to

http://dev.mysql.com/doc/refman/4.1/en/news-4-1-x.html 

or to

http://dev.mysql.com/doc/refman/5.5/en/news-5-5-x.html

Try to switch to 5.5, 5.1 or 4.1 manual with left hand side menu. You will always end up on the same page for the same version of the doc.

In my understanding this happens if there is no such document/page like the current one in the docs for the version you click (example 4.1 docs has no page named "Version 5.5 change history"). But communication could be better!

We're aware of the problem, but (a) that functionality is controlled by the Web team, and (b) this is not an easy fix.

The current implementation is to redirect back to the original page for pages that have no equivalent in another version of the MySQL Manual. Equivalent is defined as having the same ID (e.g. show-tables), which by nature is never true for change log pages (e.g. news-4-1-5 vs. news-5-5-5).

The fix would be to _disable_ navigation links for change log pages, because it doesn't make sense to switch from, say, the 4.1.5 change log to the 5.5.5 change log (since they're not related at all). But, as said, this fix is not trivial and must be done by the Web team (who are aware of the problem, too).
