 # Changelog
 
 
+## [v8.2.0](https://github.com/lvgl/lvgl/compare/v8.2.0...v8.2.0) 6 July 2022
+
+
+### Overview
+
+- **Layers** Support transforming (zoom and rotate) any widgets and their children drawn by LVGL. To do this LVGL renders the transformed widgets into a layer and draws that layer as an image applying all the transformations. Layers are also used when `opa` (not `bg_opa`, `border_opa`, etc) and `blend_mode` are set. This way nested objects are blended as one layer to avoid color bleeding. See more [here](https://docs.lvgl.io/master/overview/style.html#opacity-blend-modes-and-transformations).
+- **inherit and initial style properties** Besides setting "normal values" for style properties now you can set them to `inherit` (inherit the parent's value) and `initial` (set the system default). See more [here](https://docs.lvgl.io/master/overview/style.html#forced-value-inheritance-default-value)
+- **NXP-PXP and VGLITE GPU support** The support for NXP GPUs are added again
+- **Color font support** You can use emojis and images in texts with this great new features. See more [here](https://docs.lvgl.io/master/others/imgfont.html).
+- **ARM2D GPU support** Get support for ARM's own GPU.
+- **PubSub messaging** A publisher-subscriber based messaging system is added to make communication between components easier. See more [here](https://docs.lvgl.io/master/others/msg.html).
+- **Pinyin IME** Add support for Pinyin IME Chinese input. See more [here](https://docs.lvgl.io/master/others/ime_pinyin.html).
+- **render_start_cb** A new callback is added to `lv_disp_drv_t` to indicate when the rendering starts. It's useful to make synchronization, e.g. wait for a TE signal.
