Skip cached credits if version number doesn't match
|Reported by:||duck_||Owned by:||nacin|
When upgrading you're redirected to wp-admin/about.php (What's New) which has the credits tab. However you may be in a situation where previously cached credits for an older version will be displayed instead of for the version you have just upgraded to.
Since the credits API returns the major version (e.g. "3.3") we can that $wp_version begins with this string.
