 # Changelog
 
-## v7.4.0 (planned on 01.09.2020)
+## v7.4.0 (01.09.2020)
+
+The main new features of v7.4 are run-time font loading, style caching and arc knob with value setting by click.
 
 ### New features
-- arc: add set value by click feature
-- arc: add `LV_ARC_PART_KNOB` similarly to slider
-- send gestures even is the the obejct was dragged. User can check dragging with `lv_indev_is_dragging(lv_indev_act())` in the event function. 
 - Add `lv_font_load()` function - Loads a `lv_font_t` object from a binary font file
 - Add `lv_font_free()` function - Frees the memory allocated by the `lv_font_load()` function
 - Add style caching to reduce acces time of properties with default value
-- Add `clean_dcache_cb` and `lv_disp_clean_dcache` to enable users to use their own cache management function
-- Add `gpu_wait_cb` to wait until the GPU is working. It allows to run CPU a wait only when the rendered data is needed.
