On October 28, 2016, ePublishing will discontinue support for Transport Layer Security version 1.1.
TLS 1.1 contains security vulnerabilities that are addressed in TLS 1.2. We kept version 1.1 active to support users of Internet Explorer 10 and below. In early 2016, Microsoft announced it was no longer supporting those versions of IE.
If you wish, look at your Google Analytics to find what percentage of your users are using browsers that aren't able to use TLS 1.2. The following browser versions use this more secure protocol.
If people are using older browsers that can't use the TLS 1.2 protocol, they will likely see a security warning making them aware of a problem.
The good news is that the percentage of users on browser versions that can't handle this change is extremely small, impacting mostly IE users.
Increased security for our customers is always a top priority. If you have any questions, please send an email to firstname.lastname@example.org.
