Re: When is the next planned update for Acrobat Reader and DC?

They just turn up, pretty often. There is a high ratio of bug fixes to planned releases. This page gives an idea of frequency https://helpx.adobe.com/acrobat/release-note/release-notes-acrobat-reader.html

NB Acrobat Reader _is_ DC. It isn't Reader or DC. But there is Acrobat versus Acrobat Reader (paid versus free); Reader and Acrobat both come in Continuous or Classic threads, and Acrobat on Windows has Pro and Standard versions. Only the continuous thread is really DC.
