I had version 3.3 installed and the coupons expiration dates were not being check before they were applied. I just downloaded version 220.127.116.11 and I have 2 questions. 1 is that fixed in the new version? 2 how do I update the plugin? Do I have to remove 3.3 before installing 18.104.22.168? There is no option to update the plugin in my wp-admin.
