 * Some of the Gluon-specific i18n support code in the build system has been removed, as LuCI now provides
   similar facilities
 * The C-based `luci-lib-jsonc` library is now used for JSON encoding/decoding instead of the pure Lua `luci-lib-json`
+* The site config is now stored as JSON on the node. The Lua interface via ``gluon.site_config`` is still available, and a C interface via the newly added `libgluonutil` was added.
+* The `respondd` daemon now uses C modules instead of Lua snippets, which greatly enhances response speed and reduces memory usage.
