+* Update Tailscale to v1.92.4
+
+**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.

+
+    uTLS has had repeated fingerprinting vulnerabilities discovered by researchers.
+
+    uTLS is a Go library that attempts to imitate browser TLS fingerprints by copying

+    (Chrome uses BoringSSL, Firefox uses NSS) with distinct implementation behaviors
+    that cannot be replicated by simply copying the handshake format, making detection possible.
+    Additionally, the library lacks active maintenance and has poor code quality,
+    making it unsuitable for censorship circumvention.
+
+    For TLS fingerprint resistance, use [NaiveProxy](/configuration/inbound/naive/) instead.
 
 uTLS is a fork of "crypto/tls", which provides ClientHello fingerprinting resistance.
