 - `spectate`: improved documentation of features and functionality
 
 ## API
+- ``Lua::PushInterfaceKeys()``: transforms viewscreen ``feed()`` keys into something that can be interpreted by lua-based widgets
+- ``Lua::Push()``: now handles maps with otherwise supported keys and values
 - Constructions module: added ``insert()`` to insert constructions into the game's sorted list.
