We do not plan to end support for the Millau release (Skuid 11) until sometime next year.

All that means is that we will not go back and patch the supported version of that release when new bugs are identified - or issues emerge with Salesforce that cause problems in Skuid. You will absolutely still be able to use that version of Skuid tho. WE won’t cut you off.

Having said that - you are missing 2+ years of great new developments if you stay on Skuid 11. There are so many valuable features that you are missing, and so much investment in performance that you will not be taking advantage of. We feel it is really improtant that you upgrade to more current versions of the product.
