 # Updates
 
+- **14-Jul-2020**:
+    - sapp_mouse_shown() has been implemented for macOS (thanks to @slmjkdbtl) for
+      providing the initial PR!
+    - On macOS, the lower-level functions CGDisplayShowCursor and CGDisplayHideCursor
+      are now used instead of the NSCursor class. This is in preparation for the
+      'pointer lock' feature which will also use CGDisplay* functions.
+    - Calling ```sapp_show_mouse(bool visible)``` no longer 'stacks' (e.g. there's
+      no 'hidden counter' underneath anymore, instead calling ```sapp_show_mouse(true)```
+      will always show the cursor and ```sapp_show_mouse(false)``` will always
+      hide it. This is a different behaviour than the underlying Win32 and
+      macOS functions ShowCursor() and CGDisplaShow/HideCursor()
+    - The mouse show/hide behaviour can now be tested in the ```events-sapp``` sample
+      (so far this only works on Windows and macOS).

 - **13-Jul-2020**:
     - On macOS and iOS, sokol_app.h and sokol_gfx.h can now be compiled with
       ARC (Automatic Reference Counting) **disabled** (previously ARC had to be
