-DNS servers are refactored for better performance and scalability.
-
-See [DNS server](/configuration/dns/server/).
-
-For migration, see [Migrate to new DNS server formats](/migration/#migrate-to-new-dns-servers).
-
-Compatibility for old formats will be removed in sing-box 1.14.0.
-
-**2**:
-
-Legacy `outbound` DNS rules are deprecated
-and can be replaced by the new `domain_resolver` option.
-
-See [Dial Fields](/configuration/shared/dial/#domain_resolver) and
-[Route](/configuration/route/#default_domain_resolver).
-
-For migration,
-see [Migrate outbound DNS rule items to domain resolver](/migration/#migrate-outbound-dns-rule-items-to-domain-resolver).
-
-**3**:
-
-See [Route Action](/configuration/route/rule_action/#tls_fragment) and [TLS](/configuration/shared/tls/).
-
-**4**:
-
-New certificate options allow you to manage the default list of trusted X509 CA certificates.
-
-For the system certificate list, fixed Go not reading Android trusted certificates correctly.
-
-You can also use the Mozilla Included List instead, or add trusted certificates yourself.

-**6**:
-
-Due to maintenance difficulties, sing-box 1.12.0 requires at least Go 1.23 to compile.
-
-For Windows 7 users, legacy binaries now continue to compile with Go 1.23 and patches from [MetaCubeX/go](https://github.com/MetaCubeX/go).
-
-**7**:
-
-The new AnyTLS protocol claims to mitigate TLS proxy traffic characteristics and comes with a new multiplexing scheme.
-
-See [AnyTLS Inbound](/configuration/inbound/anytls/) and [AnyTLS Outbound](/configuration/outbound/anytls/).
-
-**8**:
