-### Migrate DNS rule action strategy to rule items
-
-Legacy `strategy` DNS rule action option is deprecated.
-
-In sing-box 1.14.0, internal domain resolution (Lookup) now splits A and AAAA queries
-at the rule level, so each query type is evaluated independently through the full rule chain.
-Use `ip_version` or `query_type` rule items to control which query types a rule matches.
