@@ -116,6 +116,7 @@ changelog.txt uses a syntax similar to RST, with a few special sequences:
 - ``widgets.EditField`` now allows other widgets to process characters that the ``on_char`` callback rejects.
 - ``gui.Screen.show()`` now returns ``self`` as a convenience
 - ``gui.View.getMousePos()`` now takes an optional ``ViewRect`` parameter in case the caller wants to get the mouse pos relative to a rect that is not the frame_body (such as the frame_rect)
+- Lua mouse events now conform to documented behavior in `lua-api` -- ``_MOUSE_L_DOWN`` will be sent exactly once per mouse click and ``_MOUSE_L`` will be sent repeatedly as long as the button is held down. Similarly for right mouse button events.
 
 ## Internals
 - MSVC warning level upped to /W3, and /WX added to make warnings cause compilations to fail.
