We spent a lot of time with our Citrix XenApp support, and especially focused on performance, which is key when accessing Adobe Reader XI from your tablet devices. And, in the area of content security, we've expanded our support to elliptic curve cryptography.

For high-risk environments, we've added the PDF Whitelisting Framework, which allows the selective enablement of JavaScript for both Windows and Mac OS, including support for certified documents.

Now, we've enhanced Protected Mode in Adobe Reader XI to include data theft prevention capabilities. We really moved the needle with Protected Mode in Adobe Reader X.
