2.9.1 needs mysql 5.1 no warning

upgrading to 2.9.1 is simply not possible for me because my host only offers mysql version 5.01. WP 2.9.1 needs mysql 5.1 and higher…
it would be such a nice idea to inform people BEFORE downloading and installing WP 2.9.1 that mysql 5.1.. is needed to make wp 2.9.1 running at all…
