m.n.xは The security/critical branches only receive fixes for security problems or other critical problems. だからまあいいとして、 m.nは What you will find on a stable branch is the last release (major or minor) plus whatever bug fixes and enhancements which will be going into the next minor release, pulled up from the NetBSD-current development branch. だからcurrentから持って来たenhancementsもありでしょ。 この言葉だけなら解釈次第だが実際の運用を見てると適当な感じ。
