-
-**1**:
-
-NaiveProxy outbound now supports QUIC, ECH, UDP over TCP, and configurable QUIC congestion control.
-
-Only available on Apple platforms, Android, Windows and some Linux architectures.
-Each Windows release includes `libcronet.dll` —
-ensure this file is in the same directory as `sing-box.exe` or in a directory listed in `PATH`.
-
-See [NaiveProxy outbound](/configuration/outbound/naive/).
-
-**2**:
-
-`auto_redirect` now allows you to bypass sing-box for connections based on routing rules.
-
-A new rule action `bypass` is introduced to support this feature. When matched during pre-match, the connection will bypass sing-box and connect directly.
-
-This feature requires Linux with `auto_redirect` enabled.
-
-See [Pre-match](/configuration/shared/pre-match/) and [Rule Action](/configuration/route/rule_action/#bypass).
-
-**3**:
-
-`auto_redirect` now rejects MPTCP connections by default to fix compatibility issues.
-You can change it to bypass sing-box via the new `exclude_mptcp` option.
-
-Adds a fallback iproute2 rule checked after system default rules (32766: main, 32767: default),
-ensuring traffic is routed to the sing-box table when no route is found in system tables.
-The rule index can be customized via `auto_redirect_iproute2_fallback_rule_index` (default: 32768).
-
-See [TUN](/configuration/inbound/tun/#exclude_mptcp).
-
-**4**:
-
-Adds `chrome` as a new certificate store option alongside `mozilla`.
-Both stores filter out China-based CA certificates.
-
-See [Certificate](/configuration/certificate/#store).
-
-**5**:
-
-See [DNS-01 Challenge](/configuration/shared/dns01_challenge/).
-
-**6**:
-
-sing-box can now monitor Wi-Fi state on Linux and Windows to enable routing rules based on `wifi_ssid` and `wifi_bssid`.
-
-See [Wi-Fi State](/configuration/shared/wifi-state/).
-
-**7**:
-
-See [TLS](/configuration/shared/tls/).
-
-**8**:
-
-Adds `kernel_tx` and `kernel_rx` options for TLS inbound.
-Enables kernel-level TLS offloading via `splice(2)` on Linux 5.1+ with TLS 1.3.
-
-See [TLS](/configuration/shared/tls/).
-
-**9**:
-
-sing-box can now proxy ICMP echo (ping) requests.
-A new `icmp` network type is available for route rules.
-Supported from TUN, WireGuard and Tailscale inbounds to Direct, WireGuard and Tailscale outbounds.
-The `reject` action can also reply to ICMP echo requests.
-
-**10**:
-
-New rule items for matching based on interface IP addresses, available in route rules, DNS rules and rule-sets.
-
-**11**:
-
-Matches outbounds' preferred routes.
-For Tailscale: MagicDNS domains and peers' allowed IPs. For WireGuard: peers' allowed IPs.
-
-**12**:
-
-The `local` DNS server now uses platform-native resolution:
-`getaddrinfo`/libresolv on Apple platforms, systemd-resolved DBus on Linux.
-A new `prefer_go` option is available to opt out.
-
-See [Local DNS](/configuration/dns/server/local/).
-
-**13**:
-
-The default TCP keep-alive initial period has been updated from 10 minutes to 5 minutes.
-
-See [Dial Fields](/configuration/shared/dial/#tcp_keep_alive).
-
-**14**:
-
-Adds the Linux socket option `IP_BIND_ADDRESS_NO_PORT` support when explicitly binding to a source address.
-
-This allows reusing the same source port for multiple connections, improving scalability for high-concurrency proxy scenarios.
-
-See [Dial Fields](/configuration/shared/dial/#bind_address_no_port).
-
-**15**:
-
-Tailscale endpoint can now create a system TUN interface to handle traffic directly.
-New `relay_server_port` and `relay_server_static_endpoints` options for incoming relay connections.
-New `advertise_tags` option for ACL tag advertisement.
-
-See [Tailscale endpoint](/configuration/endpoint/tailscale/).
-
-**16**:
-
-CCM (Claude Code Multiplexer) service allows you to access your local Claude Code subscription remotely through custom tokens, eliminating the need for OAuth authentication on remote clients.
-
-See [CCM](/configuration/service/ccm).
-
-**17**:
-
-See [OCM](/configuration/service/ocm).
-
-**18**:
-
-Due to maintenance difficulties, sing-box 1.13.0 requires at least Go 1.24 to compile.
-
-**19**:
-
-Due to maintenance difficulties, sing-box 1.13.0 will be the last version to support Android 5.0,
-and only through a separate legacy build (with `-legacy-android-5` suffix).
-
-For standalone binaries, the minimum Android version has been raised to Android 6.0,
-since Termux requires Android 7.0 or later.
-
-**20**:
-
-This update fixes missing padding extension for Chrome 120+ fingerprints.
-
-Also, documentation has been updated with a warning about uTLS fingerprinting vulnerabilities.
-uTLS is not recommended for censorship circumvention due to fundamental architectural limitations;
-use NaiveProxy instead for TLS fingerprint resistance.
