bump of PORTREVISION mandatory?

[Helmut Schneider]

Hi,

with the release of Typo3 4.5, 4.4 becomes "old stable", 4.3 becomes
"deprecated". Therefore a change at pkg_descr is required. That is the
only change.

Do I need to bump PORTREVISION before I submit the updated port? Is
that mandatory?

I don't like the idea that someone is asked to update his/her installed
package only because of a changed pkg_descr.

Thanks, Helmut
