The parsing has changed, and to me that is the important part, for the 
reason you highlighted above.

However, the URL generator has also changed, in that it creates URLs with 
`;' instead of `&'.

Both of these are noteworthy: the parser changing, because the parser is now 
stricter about what can be a value and what can be a key; the generator 
changing, because it could lead to confusion about what is going on
(many CGI and Web programming courses still teach `&' instead of `;', even 
though Perl, Python, and Java support both).
