Description: 

DRUPAL_MINIMUM_PHP is now set to PHP 5.3.3 in Drupal 7.

As mentioned in the updated INSTALL.txt this represents the minimum version that D7 core is routinely tested with.

It is highly recommended that Drupal 7 sites use a (much) more modern version of PHP if possible.

After this change, it will no longer be possible to run update.php or install.php on versions of PHP before 5.3.3.
