## [v8.3.0](https://github.com/lvgl/lvgl/compare/v8.2.0...v8.3.0) 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.

## v8.0.0 (01.06.2021)
v8.0 brings many new features like simplified and more powerful scrolling, new layouts inspired by CSS Flexbox and Grid, simplified and improved widgets, more powerful events, hookable drawing, and more.
v8 is a major change and therefore it's not backward compatible with v7.
### Directory structure
- The `lv_` prefix is removed from the folder names
- The `docs` is moved to the `lvgl` repository
- The `examples` are moved to the `lvgl` repository
- Create an `src/extra` folder for complex widgets:
- It makes the core LVGL leaner
- In `extra` we can have a lot and specific widgets
- Good place for contributions
### Widget changes
-`lv_cont` removed, layout features are moved to `lv_obj`
-`lv_page` removed, scroll features are moved to `lv_obj`
-`lv_objmask` the same can be achieved by events
-`lv_meter` added as the union of `lv_linemeter` and `lv_gauge`
-`lv_span` new widget mimicking HTML `<span>`
-`lv_animing` new widget for simple slideshow animations
- \+ many minor changes and improvements
### New scrolling
- Support "elastic" scrolling when scrolled in
- Support scroll chaining among any objects types (not only `lv_pages`s)
- Remove `lv_drag`. Similar effect can be achieved by setting the position in `LV_EVENT_PRESSING`
- Add snapping
- Add snap stop to scroll max 1 snap point
### New layouts
- [CSS Grid](https://css-tricks.com/snippets/css/a-guide-to-grid/)-like layout support
- [CSS Flexbox](https://css-tricks.com/snippets/css/a-guide-to-flexbox/)-like layout support
### Styles
- Optimize and simplify styles
- State is saved in the object instead of the style property
- Object size and position can be set in styles too
### Events
- Allow adding multiple events to an object
- A `user_data` can be attached to the added events
### Driver changes
-`lv_disp_drv_t`, `lv_indev_drv_t`, `lv_fs_drv_t` needs to be `static`
-`...disp_buf...` is renamed to `draw_buf`. See an initialization example [here](https://github.com/lvgl/lv_sim_eclipse_sdl/blob/release/v8.0/main.c#L128-L141).
- No partial update if two screen sized buffers are set
-`disp_drv->full_refresh = 1` makes always the whole display redraw.
-`hor_res` and `ver_res` need to be set in `disp_drv`
-`indev_read_cb` returns `void`. To indicate that there is more that to read set `data->continue_reading = 1` in the `read_cb`
### Other changes
- Remove the copy parameter from create functions
- Simplified File system interface API
- Use a more generic inheritance
- The built-in themes are reworked
-`lv_obj_align` now saved the alignment and realigns the object automatically but can't be used to align to other than the parent
-`lv_obj_align_to` can align to an object but doesn't save the alignment
-`lv_pct(x)` can be used to set the size and position in percentage
- There are many other changes in widgets that are not detailed here. Please refer to the documentation of the widgets.
### New release policy
- We will follow [Release branches with GitLab flow](https://docs.gitlab.com/ee/topics/gitlab_flow.html#release-branches-with-gitlab-flow)
- Minor releases are expected in every 3-4 month
-`master` will always contain the latest changes
### Migrating from v7 to v8
- First and foremost, create a new `lv_conf.h` based on `lv_conf_template.h`.
- To try the new version it's recommended to use a simulator project and see the examples.
- When migrating your project to v8
- Update the drivers are described above
- Update the styles
- Update the events
- Use the new layouts instead of `lv_cont` features
- Use `lv_obj` instead of `lv_page`
- See the changes in [Colors](https://docs.lvgl.io/8.0/overview/color.html)
- The other parts are mainly minor renames and refactoring. See the functions' documentation for descriptions.

- *value* display a text which is stored in the style. It can be used e.g. as a light-weighted text on buttons too.
- *margin*: similar to *padding* but used to keep space outside the object
Read the [Style](https://docs.littlevgl.com/v7/en/html/overview/style.html) section of the documentation to learn how the new styles system works.
### GPU integration
To better utilize GPUs, from this version GPU usage can be integrated into LVGL. In `lv_conf.h` any supported GPUs can be enabled with a single configuration option.
Right now, only ST's DMA2D (Chrom-ART) is integrated. More will in the upcoming releases.
-`dropdown`: Completely reworked. Now creates a separate list when opened and can be dropped to down/up/left/right.
-`label`: `body_draw` is removed, instead, if its style has a visible background/border/shadow etc it will be drawn. Padding really makes the object larger (not just virtually as before)
-`arc`: can draw background too.
-`btn`: doesn't store styles for each state because it's done naturally in the new style system.
-`calendar`: highlight the pressed datum. The used styles are changed: use `LV_CALENDAR_PART_DATE` normal for normal dates, checked for highlighted, focused for today, pressed for the being pressed. (checked+pressed, focused+pressed also work)
-`chart`: only has `LINE` and `COLUMN` types because with new styles all the others can be described. LV_CHART_PART_SERIES sets the style of the series. bg_opa > 0 draws an area in LINE mode. `LV_CHART_PART_SERIES_BG` also added to set a different style for the series area. Padding in `LV_CHART_PART_BG` makes the series area smaller, and it ensures space for axis labels/numbers.
-`linemeter`, `gauge`: can have background if the related style properties are set. Padding makes the scale/lines smaller. scale_border_width and scale_end_border_width allow to draw an arc on the outer part of the scale lines.
-`gauge`: `lv_gauge_set_needle_img` allows use image as needle
-`canvas`: allow drawing to true color alpha and alpha only canvas, add `lv_canvas_blur_hor/ver` and rename `lv_canvas_rotate` to `lv_canvas_transform`
-`textarea`: If available in the font use bullet (`U+2022`) character in text area password
### New object types
-`lv_objmask`: masks can be added to it. The children will be masked accordingly.
### Others
- Change the built-in fonts to [Montserrat](https://fonts.google.com/specimen/Montserrat) and add built-in fonts from 12 px to 48 px for every 2nd size.
- Add example CJK and Arabic/Persian/Hebrew built-in font
- Add ° and "bullet" to the built-in fonts
- Add Arabic/Persian script support: change the character according to its position in the text.
- Add `playback_time` to animations.
- Add `repeat_count` to animations instead of the current "repeat forever".
- Replace `LV_LAYOUT_PRETTY` with `LV_LAYOUT_PRETTY_TOP/MID/BOTTOM`
### Demos
- [lv_examples](https://github.com/littlevgl/lv_examples) was reworked and new examples and demos were added
### New release policy
- Maintain this Changelog for every release
- Save old major version in new branches. E.g. `release/v6`
- Merge new features and fixes directly into `master` and release a patch or minor releases every 2 weeks.
### Migrating from v6 to v7
- First and foremost, create a new `lv_conf.h` based on `lv_conf_template.h`.
- To try the new version it suggested using a simulator project and see the examples.
- If you have a running project, the most difficult part of the migration is updating to the new style system. Unfortunately, there is no better way than manually updating to the new format.
- The other parts are mainly minor renames and refactoring as described above.
