On this page: Version naming convention PaperCut-supported versions Support inclusions for each Major version Definitions Version naming convention PaperCut uses a three-part release naming convention to communicate versioning for PaperCut NG/MF: M.n.r M is the major version n is the minor version r is the minor version revision For example, at the time of writing, the latest version of PaperCut NG/MF is 22.1.3. M = 22 n = 1 r = 3 PaperCut-supported versions PaperCut-supported versions are defined as M - 2 (M minus 2), that is, the current Major [M] version and the two previous Major [M] versions.
