commit 22891e12a45f9bb2e1dbb5daf2ba39cbe002e4f4 Author: Juergen Gross <jgross@xxxxxxxx> AuthorDate: Tue Jan 11 11:43:48 2022 +0100 Commit: Jan Beulich <jbeulich@xxxxxxxx> CommitDate: Tue Jan 11 11:43:48 2022 +0100 SUPPORT.md: limit support statement for Linux and Windows frontends Change the support state of Linux and Windows pv frontends from "supported" to "supported with caveats" in order to reflect that the frontends can probably be harmed by their respective backends. Some of the Linux frontends have been hardened already.
