Breaking change (level: error)
oasdiff reports this as a breaking change by default. It can break existing API clients, so CI fails on it unless you downgrade its severity.
Change its severity or ignore it
To change the severity oasdiff assigns to api-deprecated-sunset-missing, list its id and a level in a severity-levels file, one rule per line. The level can be err, warn, or info, or none to disable the check entirely:
# severity.txt
api-deprecated-sunset-missing warnThen pass it to oasdiff:
oasdiff changelog base.yaml revision.yaml --severity-levels severity.txtSetting the level to none disables the check, so it is no longer reported at all.
