+#### 1.12.0-alpha.5

+
+* Fixes and improvements
+
+### 1.11.1
+
+* Fixes and improvements
+
+#### 1.12.0-alpha.2
+
+* Update quic-go to v0.49.0
+* Fixes and improvements
+
+#### 1.12.0-alpha.1
+
+* Refactor DNS servers **1**
+* Add domain resolver options**2**
+* Add TLS fragment route options **3**
+* Add certificate options **4**
+
+**1**:
+
+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**:
+
+The new TLS fragment route options allow you to fragment TLS handshakes to bypass firewalls.
+
+This feature is intended to circumvent simple firewalls based on **plaintext packet matching**, and should not be used
+to circumvent real censorship.
+
+Since it is not designed for performance, it should not be applied to all connections, but only to server names that are
+known to be blocked.
+
+See [Route Action](/configuration/route/rule_action/#tls_fragment).
+
+**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.
+
+See [Certificate](/configuration/certificate/).
+
+### 1.11.0
+
+Important changes since 1.10:
+
+* Introducing rule actions **1**
+* Improve tun compatibility **3**
+* Merge route options to route actions **4**
+* Add `network_type`, `network_is_expensive` and `network_is_constrainted` rule items **5**
+* Add multi network dialing **6**
+* Add `cache_capacity` DNS option **7**
+* Add `override_address` and `override_port` route options **8**
+* Upgrade WireGuard outbound to endpoint **9**
+* Add UDP GSO support for WireGuard
+* Make GSO adaptive **10**
+* Add UDP timeout route option **11**
+* Add more masquerade options for hysteria2 **12**
+* Add `rule-set merge` command
+* Add port hopping support for Hysteria2 **13**
+* Hysteria2 `ignore_client_bandwidth` behavior update **14**
+
+**1**:
+
+New rule actions replace legacy inbound fields and special outbound fields,
+and can be used for pre-matching **2**.
+
+See [Rule](/configuration/route/rule/),
+[Rule Action](/configuration/route/rule_action/),
+[DNS Rule](/configuration/dns/rule/) and
+[DNS Rule Action](/configuration/dns/rule_action/).
+
+For migration, see
+[Migrate legacy special outbounds to rule actions](/migration/#migrate-legacy-special-outbounds-to-rule-actions),
+[Migrate legacy inbound fields to rule actions](/migration/#migrate-legacy-inbound-fields-to-rule-actions)
+and [Migrate legacy DNS route options to rule actions](/migration/#migrate-legacy-dns-route-options-to-rule-actions).
+
+**2**:
+
+Similar to Surge's pre-matching.
+
+Specifically, new rule actions allow you to reject connections with
+TCP RST (for TCP connections) and ICMP port unreachable (for UDP packets)
+before connection established to improve tun's compatibility.
+
+See [Rule Action](/configuration/route/rule_action/).
+
+**3**:
+
+When `gvisor` tun stack is enabled, even if the request passes routing,
+if the outbound connection establishment fails,
+the connection still does not need to be established and a TCP RST is replied.
+
+**4**:
+
+Route options in DNS route actions will no longer be considered deprecated,
+see [DNS Route Action](/configuration/dns/rule_action/).
+
+Also, now `udp_disable_domain_unmapping` and `udp_connect` can also be configured in route action,
+see [Route Action](/configuration/route/rule_action/).
+
+**5**:
+
+When using in graphical clients, new routing rule items allow you to match on
+network type (WIFI, cellular, etc.), whether the network is expensive, and whether Low Data Mode is enabled.
+
+See [Route Rule](/configuration/route/rule/), [DNS Route Rule](/configuration/dns/rule/)
+and [Headless Rule](/configuration/rule-set/headless-rule/).
+
+**6**:
+
+Similar to Surge's strategy.
+
+New options allow you to connect using multiple network interfaces,
+prefer or only use one type of interface,
+and configure a timeout to fallback to other interfaces.
+
+See [Dial Fields](/configuration/shared/dial/#network_strategy),
+[Rule Action](/configuration/route/rule_action/#network_strategy)
+and [Route](/configuration/route/#default_network_strategy).
+
+**7**:
+
+See [DNS](/configuration/dns/#cache_capacity).
+
+**8**:
+
+See [Rule Action](/configuration/route/#override_address) and
+[Migrate destination override fields to route options](/migration/#migrate-destination-override-fields-to-route-options).
+
+**9**:
+
+The new WireGuard endpoint combines inbound and outbound capabilities,
+and the old outbound will be removed in sing-box 1.13.0.
+
+See [Endpoint](/configuration/endpoint/), [WireGuard Endpoint](/configuration/endpoint/wireguard/)
+and [Migrate WireGuard outbound fields to route options](/migration/#migrate-wireguard-outbound-to-endpoint).
+
+**10**:
+
+For WireGuard outbound and endpoint, GSO will be automatically enabled when available,
+see [WireGuard Outbound](/configuration/outbound/wireguard/#gso).
+
+For TUN, GSO has been removed,
+see [Deprecated](/deprecated/#gso-option-in-tun).
+
+**11**:
+
+See [Rule Action](/configuration/route/rule_action/#udp_timeout).
+
+**12**:
+
+See [Hysteria2](/configuration/inbound/hysteria2/#masquerade).
+
+**13**:
+
+See [Hysteria2](/configuration/outbound/hysteria2/).
+
+**14**:
+
+When `up_mbps` and `down_mbps` are set, `ignore_client_bandwidth` instead denies clients from using BBR CC.
