From 8cc461c18554e058a6dcd5cdebea1fdcba3debb7 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Wed, 11 Aug 2021 10:40:59 +0200 Subject: docs/about/removed-features: Document removed CLI options from QEMU v3.0 These CLI options had been removed/replaced in QEMU v3.0. Still, some people might want to update from older versions to the recent QEMU version, so we should give some recommendations for the replacements in our documentation.
