+
+**1**:
+
+Alpine APK files use `linux` in the filename to distinguish from OpenWrt APKs which use the `openwrt` prefix:
+
+- OpenWrt: `sing-box_{version}_openwrt_{architecture}.apk`
+- Alpine: `sing-box_{version}_linux_{architecture}.apk`
+
+**2**:
+
+Legacy macOS binaries (with `-legacy-macos-10.13` suffix) now support
+macOS 10.13 High Sierra, built using Go 1.25 with patches
+from [SagerNet/go](https://github.com/SagerNet/go).
+
+**3**:
+
+See [OCM](/configuration/service/ocm).
+
+#### 1.14.0-alpha.1
+
+* Add `source_mac_address` and `source_hostname` rule items **1**
+* Add `include_mac_address` and `exclude_mac_address` TUN options **2**
+* Update NaiveProxy to 145.0.7632.159 **3**
+* Fixes and improvements
+
+**1**:
+
+New rule items for matching LAN devices by MAC address and hostname via neighbor resolution.
+Supported on Linux, macOS, or in graphical clients on Android and macOS.
+
+See [Route Rule](/configuration/route/rule/#source_mac_address), [DNS Rule](/configuration/dns/rule/#source_mac_address) and [Neighbor Resolution](/configuration/shared/neighbor/).
+
+**2**:
+
+Limit or exclude devices from TUN routing by MAC address.
+Only supported on Linux with `auto_route` and `auto_redirect` enabled.
+
+See [TUN](/configuration/inbound/tun/#include_mac_address).
+
+**3**:
+
+This is not an official update from NaiveProxy. Instead, it's a Chromium codebase update maintained by Project S.
