Magento just released a new version incorporating an important security update:
Magento Community Edition 220.127.116.11 corrects a remote code execution vulnerability that makes it possible for unauthorized persons to gain access to your store. In February of this year, we released patch SUPEE-5344 to correct the problem. That patch is incorporated into this release.We recommend everyone that hasn't applied patch SUPEE-5344 to immediately upgrade to secure their installation. As always, feel free to contact our support if you want to purchase our professional Magento upgrade service.
