 ## Changelog since 3.4
 
+ - Added `glfwSetWindowProgressIndicator` for displaying progress on the dock or taskbar (#2286,#1183)
  - Added `GLFW_UNLIMITED_MOUSE_BUTTONS` input mode that allows mouse buttons beyond
    the limit of the mouse button tokens to be reported (#2423)
  - Updated minimum CMake version to 3.16 (#2541)

+### Window progress indicator {#window_progress_indicator}
+
+If you wish to display the progress of some action on the Dock icon or task bar, you can
+do this with @ref glfwSetWindowProgressIndicator.
+
+```c
+glfwSetWindowProgressIndicator(window, GLFW_PROGRESS_INDICATOR_NORMAL, 0.5);
+```
+
+There are different progress states available for you to use:
+    - @ref GLFW_PROGRESS_INDICATOR_DISABLED
+    - @ref GLFW_PROGRESS_INDICATOR_INDETERMINATE
+    - @ref GLFW_PROGRESS_INDICATOR_NORMAL
+    - @ref GLFW_PROGRESS_INDICATOR_ERROR
+    - @ref GLFW_PROGRESS_INDICATOR_PAUSED
+
+The last argument is the progress percentage to display.
+It has a valid range of 0.0 to 1.0.
