          ## Linux release assets

          - `CLIProxyAPI_<version>_linux_<arch>.tar.gz` is the default Linux build. It supports dynamic library plugins and is built against a GLIBC 2.17 baseline.
          - `CLIProxyAPI_<version>_linux_<arch>_no-plugin.tar.gz` is the portable Linux build for musl-based or older systems such as OpenWrt. It does not support dynamic library plugins.
