 	* uiAreas on Windows and some internal Direct2D areas now respond to `WM_PRINTCLIENT` properly, which should hopefully increase the quality of screenshots.
 	* uiDateTimePicker on GTK+ works properly on RTL layouts and no longer disappears off the bottom of the screen if not enough room is available. It will also no longer be marked for localization of the time format (what the separator should be and whether to use 24-hour time), as that information is not provided by the locale system. :(
 	* Added `uiUserBugCannotSetParentOnToplevel()`, which should be used by implementations of toplevel controls in their `SetParent()` implementations. This will also be the beginning of consolidating common user bug messages into a single place, though this will be one of the only few exported user bug functions.
+	* uiSpinbox and uiSlider now merely swap their min and max if min ≥ max. They will no longer panic and do nothing, respectively.
 
 ## Runtime Requirements
