The Smart TV Alliance has been updated Smart TV Alliance SDK Application Development and UI Guidelines 3.0.1

[Support_STA]

The update from the previous version is to update the section 3.11 as written below.

When you design secure applications, e.g. such that require a payment interface, and load (part of) your application over HTTPS, please refrain from SSL in your server and instead rely on TLS 1.1. Reason is that multiple vulnerabilities were found in SSL versions 3.0 and older, and that using these protocols will make your app less secure.
