Can someone clarify the latest release notes for me, please?

Under “Changes since last beta” it says:

Changes since last beta:
- Fixed crash playing photos and videos for users using iOS 11 beta (PLEASE UPDATE TO FINAL VERSIONS, WE WON'T SUPPORT BETA VERSIONS ANY LONGER).

Does that last portion refer to general support until the next version of the beta, or that beta versions aren’t supported in any fashion (which I expect - they are beta after all)?

I understand it as iOS11 Beta will be no longer supported because iOS11 has been released.

Exactly what @“Bartlomiej Baraniec” says. Sorry that part was ambiguous!
