Email "Updates to FairPlay Streaming Server SDK" makes no sense

Hi, While I don't normally use FairPlay, I got this email that is so strangely worded I am wondering if it makes sense to people who do know it or if it has some typo or what.

You can only generate certificates for SDK 4, also SDK 4 is no longer supported?

(Also "will not expire" is imprecise phrasing, certificates presumably will expire, I think it meant to say are still valid / are not invalidated.)
