[PATCH v3 25/34] qapi: New special feature flag "deprecated" |
Date: |
Sun, 15 Mar 2020 15:46:44 +0100 |
Unlike regular feature flags, the new special feature flag
"deprecated" is recognized by the QAPI generator. For now, it's only
permitted with commands, events, and struct members. It will be put
to use shortly.
