From 278fc2f7d3425dfbc6aa91644bffc65e94afad7c Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Thu, 18 Mar 2021 16:55:12 +0100 Subject: qapi: Implement deprecated-output=hide for QMP events This policy suppresses deprecated bits in output, and thus permits "testing the future". Implement it for QMP events: suppress deprecated ones. No QMP event is deprecated right now.
