Just busy with a site of a friend and the following deprecated.log comes up when a customer looks at items in the shopping cart. Occurs in both English and French mode.

--> PHP Deprecated: strstr(): Non-string needles will be interpreted as strings in the future. Use an explicit chr() call to preserve the current behavior in /includes/modules/shipping/zones.php on line 282.

Yep. The fix for this is to change

if (strstr(MODULE_SHIPPING_ZONES_SKIPPED, $dest_country)) {

to

if (strpos(MODULE_SHIPPING_ZONES_SKIPPED, $dest_country) !== false) {
