href="https://github.com/lvgl/lvgl/commit/29bfe604">29bfe604</a> 979 980## v8.0.0 (01.06.2021) 981 982v8.0 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. 983 984v8 is a major change and therefore it's not backward compatible with v7. 985 986### Directory structure 987- The `lv_` prefix is removed from the folder names 988- The `docs` is moved to the `lvgl` repository 989- The `examples` are moved to the `lvgl` repository 990- Create an `src/extra` folder for complex widgets: 991 - It makes the core LVGL leaner 992 - In `extra` we can have a lot and specific widgets 993 - Good place for contributions 994 995### Widget changes 996- `lv_cont` removed, layout features are moved to `lv_obj` 997- `lv_page` removed, scroll features are moved to `lv_obj` 998- `lv_objmask` the same can be achieved by events 999- `lv_meter` added as the union of `lv_linemeter` and `lv_gauge` 1000- `lv_span` new widget mimicking HTML `<span>` 1001- `lv_animing` new widget for simple slideshow animations 1002- \+ many minor changes and improvements 1003 1004### New scrolling 1005- Support "elastic" scrolling when scrolled in 1006- Support scroll chaining among any objects types (not only `lv_pages`s) 1007- Remove `lv_drag`. Similar effect can be achieved by setting the position in `LV_EVENT_PRESSING` 1008- Add snapping 1009- Add snap stop to scroll max 1 snap point 1010 1011### New layouts 1012- [CSS Grid](https://css-tricks.com/snippets/css/a-guide-to-grid/)-like layout support 1013- [CSS Flexbox](https://css-tricks.com/snippets/css/a-guide-to-flexbox/)-like layout support 1014 1015### Styles 1016- Optimize and simplify styles 1017- State is saved in the object instead of the style property 1018- Object size and position can be set in styles too 1019 1020### Events 1021- Allow adding multiple events to an object 1022- A `user_data` can be attached to the added events 1023 1024### Driver changes 1025- `lv_disp_drv_t`, `lv_indev_drv_t`, `lv_fs_drv_t` needs to be `static` 1026- `...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). 1027- No partial update if two screen sized buffers are set 1028- `disp_drv->full_refresh = 1` makes always the whole display redraw. 1029- `hor_res` and `ver_res` need to be set in `disp_drv` 1030- `indev_read_cb` returns `void`. To indicate that there is more that to read set `data->continue_reading = 1` in the `read_cb` 1031 1032### Other changes 1033- Remove the copy parameter from create functions 1034- Simplified File system interface API 1035- Use a more generic inheritance 1036- The built-in themes are reworked 1037- `lv_obj_align` now saved the alignment and realigns the object automatically but can't be used to align to other than the parent 1038- `lv_obj_align_to` can align to an object but doesn't save the alignment 1039- `lv_pct(x)` can be used to set the size and position in percentage 1040- There are many other changes in widgets that are not detailed here. Please refer to the documentation of the widgets. 1041 1042### New release policy 1043- We will follow [Release branches with GitLab flow](https://docs.gitlab.com/ee/topics/gitlab_flow.html#release-branches-with-gitlab-flow) 1044- Minor releases are expected in every 3-4 month 1045- `master` will always contain the latest changes 1046 1047### Migrating from v7 to v8 1048- First and foremost, create a new `lv_conf.h` based on `lv_conf_template.h`. 1049- To try the new version it's recommended to use a simulator project and see the examples. 1050- When migrating your project to v8 1051 - Update the drivers are described above 1052 - Update the styles 1053 - Update the events 1054 - Use the new layouts instead of `lv_cont` features 1055 - Use `lv_obj` instead of `lv_page` 1056 - See the changes in [Colors](https://docs.lvgl.io/8.0/overview/color.html) 1057 - The other parts are mainly minor renames and refactoring. See the functions' documentation for descriptions. 1058 1059## v7.11.0 (16.03.2021) 1060 1061### New features 1062- Add better screen orientation management with software rotation support 1063- Decide

1371 1372## v7.0.0 (18.05.2020) 1373 1374### Documentation 1375The docs for v7 is available at https://docs.littlevgl.com/v7/en/html/index.html 1376 1377### Legal changes 1378 1379The name of the project is changed to LVGL and the new website is on https://lvgl.io 1380 1381LVGL remains free under the same conditions (MIT license) and a company is created to manage LVGL and offer services. 1382 1383### New drawing system 1384Complete rework of LVGL's draw engine to use "masks" for more advanced and higher quality graphical effects. 1385A possible use-case of this system is to remove the overflowing content from the rounded edges. 1386It also allows drawing perfectly anti-aliased circles, lines, and arcs. 1387Internally, the drawings happen by defining masks (such as rounded rectangle, line, angle). 1388When something is drawn the currently active masks can make some pixels transparent. 1389For example, rectangle borders are drawn by using 2 rectangle masks: one mask removes the inner part and another the outer part. 1390 1391The API in this regard remained the same but some new functions were added: 1392- `lv_img_set_zoom`: set image object's zoom factor 1393- `lv_img_set_angle`: set image object's angle without using canvas 1394- `lv_img_set_pivot`: set the pivot point of rotation 1395 1396The new drawing engine brought new drawing features too. They are highlighted in the "style" section. 1397 1398### New style system 1399The old style system is replaced with a new more flexible and lightweighted one. 1400It uses an approach similar to CSS: support cascading styles, inheriting properties and local style properties per object. 1401As part of these updates, a lot of objects were reworked and the APIs have been changed. 1402 1403- more shadows options: *offset* and *spread* 1404- gradient stop position to shift the gradient area and horizontal gradient 1405- `LV_BLEND_MODE_NORMAL/ADDITIVE/SUBTRACTIVE` blending modes 1406- *clip corner*: crop the content on the rounded corners 1407- *text underline* and *strikethrough* 1408- dashed vertical and horizontal lines (*dash gap*, *dash_width*) 1409- *outline*: a border-like part drawn out of the background. Can have spacing to the background. 1410- *pattern*: display and image in the middle of the background or repeat it 1411- *value* display a text which is stored in the style. It can be used e.g. as a light-weighted text on buttons too. 1412- *margin*: similar to *padding* but used to keep space outside the object 1413 1414Read the [Style](https://docs.littlevgl.com/v7/en/html/overview/style.html) section of the documentation to learn how the new styles system works. 1415 1416### GPU integration 1417To 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. 1418 1419Right now, only ST's DMA2D (Chrom-ART) is integrated. More will in the upcoming releases. 1420 1421### Renames 1422The following object types are renamed: 1423- sw -> switch 1424- ta -> textarea 1425- cb -> checkbox 1426- lmeter -> linemeter 1427- mbox -> msgbox 1428- ddlist -> dropdown 1429- btnm -> btnmatrix 1430- kb -> keyboard 1431- preload -> spinner 1432- lv_objx folder -> lv_widgets 1433- LV_FIT_FILL -> LV_FIT_PARENT 1434- LV_FIT_FLOOD -> LV_FLOOD_MAX 1435- LV_LAYOUT_COL_L/M/R -> LV_LAYOUT_COLUMN_LEFT/MID/RIGHT 1436- LV_LAYOUT_ROW_T/M/B -> LV_LAYOUT_ROW_TOP/MID/BOTTOM 1437 1438### Reworked and improved object 1439- `dropdown`: Completely reworked. Now creates a separate list when opened and can be dropped to down/up/left/right. 1440- `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) 1441- `arc`: can draw background too. 1442- `btn`: doesn't store styles for each state because it's done naturally in the new style system. 1443- `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) 1444- `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. 1445- `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. 1446- `gauge`: `lv_gauge_set_needle_img` allows use image as needle 1447- `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` 1448- `textarea`: If available in the font use bullet (`U+2022`) character in text area password 1449 1450### New object types 1451- `lv_objmask`: masks can be added to it. The children will be masked accordingly. 1452 1453### Others 1454- 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. 1455- Add example CJK and Arabic/Persian/Hebrew built-in font 1456- Add ° and "bullet" to the built-in fonts 1457- Add Arabic/Persian script support: change the character according to its position in the text. 1458- Add `playback_time` to animations. 1459- Add `repeat_count` to animations instead of the current "repeat forever". 1460- Replace `LV_LAYOUT_PRETTY` with `LV_LAYOUT_PRETTY_TOP/MID/BOTTOM` 1461 1462### Demos 1463- [lv_examples](https://github.com/littlevgl/lv_examples) was reworked and new examples and demos were added 1464 1465### New release policy 1466- Maintain this Changelog for every release 1467- Save old major version in new branches. E.g. `release/v6` 1468- Merge new features and fixes directly into `master` and release a patch or minor releases every 2 weeks. 1469 1470### Migrating from v6 to v7 1471- First and foremost, create a new `lv_conf.h` based on `lv_conf_template.h`. 1472- To try the new version it suggested using a simulator project and see the examples. 1473- 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. 1474- The other parts are mainly minor renames and refactoring as described above. 1475
