v9.6.0 Change Log

Summary of the changes of LVGL v9.6.0

v9.6.0 (16 September 2026)

LVGL v9.6.0 is the last release of the v9 series, and it is what we're considering a stability release. This release goes back over the foundations: the software renderer blend paths were rewritten and are measurably faster on every target without a GPU, the public API now lives in its own directory so internal refactors stop being breaking changes, the three ways of configuring LVGL were collapsed onto one source of truth, the whole public API validates its arguments instead of dereferencing them, and LVGL builds, installs and links like any other system library, including as an apt install on Ubuntu. Test coverage rose from 78.7% to 82.2% along the way.

Everything marked LV_DEPRECATED in this release is removed in v10.0. Old names still compile and emit a #warning, so v9.6 is the release to upgrade to and clean up on. See the migration guide for the full list.

Main Features

Faster software renderer: The blend and transform paths were rewritten to work a word at a time instead of a pixel at a time. No configuration change is needed. On the boards we measured, the average render time drops 25% on a Renesas RA8D2, 22% on an NXP i.MX RT700 and 20% on an NXP FRDM-MCXN947. Individual scenes go much further: alpha-blended images drop 76% on the RA8D2 and 60% on the RT700. The Espressif ESP32-P4 draws the rotated-ARGB scene 66% faster, taking it from 27 to a capped 60 FPS. Compositing follows, with an ESP32-S3-Korvo-1 rendering a frame with layered opacitity 14 ms faster. Learn more.
Public and private api separation: The public API moved to include/lvgl/. src/ is now private by definition. Old include paths still compile with a #warning. Internal types remain reachable through lvgl_private.h or LV_USE_PRIVATE_API. Learn more.
Kconfig as the single source of truth: lv_conf_template.h, the internal defaults header and the CONFIG_* bridge are now generated from one Kconfig tree, so lv_conf.h, Kconfig and -D defines can no longer disagree. Hand-written lv_conf.h remains fully supported. Learn more.
Argument checking: LV_CHECK_ARG replaces scattered asserts and silent dereferences with one mechanism: roughly 2,900 checks across 168 source files covering the public API. Enabled by default; logging and assert-on-failure are opt-in. Learn more.
LVGL now fetches its own dependencies: Before v9.6 you installed SDL2, FreeType, GStreamer, libdrm and the rest yourself before LVGL would configure. Now every dependency is resolved through find_package, then pkg-config, and anything still missing is fetched and built from source. Learn more.
Install and link like a system library: An installed LVGL now ships lvgl.pc and lvglConfig.cmake naming every library it was compiled against, and configs/defconfigs/ provides ready-made presets for sdl2, wayland and drm. Ubuntu packages are published through a Launchpad PPA. Learn more about LVGL's cmake and ubuntu integration.

Rendering & Performance

Faster software renderer: Software renderer is now faster, see above.
Arm SVE2 Acceleration: Vector acceleration for the RGB888 blenders on Armv9-A cores. Enable with LV_USE_DRAW_SW_ASM set to LV_DRAW_SW_ASM_SVE2. Joins NEON, Helium and RISC-V V.
SiFli EPIC Draw Unit: Initial hardware acceleration support for the EPIC 2D accelerator on SiFli SF32 parts, covering fills, blends, images, borders, labels and layers, with an OS adaptation layer. This is a first integration: it is not documented yet and does not match SiFli's out-of-tree draw unit on every scene. It is being carried into v10, where the documentation and the remaining performance work land.
NanoVG: Blur and drop shadow on the GPU, plus image recolor and more style properties support.
VG-Lite: Matrix transformation on images
NemaGFX: Cache management, a command-end wait in non-OS builds, and a float literal fix that kept the matrix path off double-precision soft-float. Selecting the Nema libraries through Kconfig works again.
DMA2D: Cache handling reworked onto lv_draw_buf, ASYNC/INTERRUPT support on Zephyr, a warning when buffers are misaligned, and the image and fill paths de-duplicated.
Object style cache is now enabled by default, blur invalidation is expanded once per frame instead of per draw, arc invalidation skips hidden knobs and unchanged angles, and I1/I2/I4 image decoding got a fast path.

Drivers

Wayland DMA-BUF Backend: LVGL now copies the rendered buffer into a DMA-BUF-backed buffer attached through linux-dmabuf, with no texture upload and no GPU involvement. On a Renesas RZ/G2L at 1280×720 this takes the all-scenes average from 32 to 44 FPS and flush time from 19 ms to 12 ms, with render time unchanged. The driver also falls back between backends automatically when one is unavailable. Learn more.
Wayland: Buffered keyboard input so key presses are not dropped, better pointer and touch responsiveness, physical outputs identified by connector name and an API to read fullscreen and maximized state.
DRM: A libdrm fallback for device probing.
fbdev: L8 support.
SDL: Runtime color format changes for the software backend.
evdev: Raw keycodes can now be queried directly.

Testing & Quality

Coverage went from 78.66% to 82.23% (+3.57 pp) over the release cycle. Covered lines rose by 9,265 as the codebase grew by 8,687 coverable lines. Branch coverage rose to 62.59% and function coverage to 83.7%.

Fonts and Text

Text Leading Trim: text_leading_trim trims a font's line-box leading against cap height, x-height or the baseline, so LV_SIZE_CONTENT labels and the buttons wrapping them size to the glyphs instead of the font's phantom space. Learn more.
Variable Font Weights: FreeType faces with a wght axis can be instantiated at any weight on that axis, baked in when the face is opened and part of the font's cache key. Learn more.
Binary fonts now support dynamic glyph loading. Learn more

Widgets

Shared glTF Models: A model can be loaded once and handed to any number of lv_gltf viewers; parsing, textures, meshes and shaders are paid for once. Adds model add/remove APIs and direct control of animation position with lv_gltf_model_set_animation_time() and lv_gltf_model_set_animation_ratio().
Dedicated State API: lv_obj_set_checked(), lv_obj_is_pressed(), lv_obj_set_disabled() and friends replace the generic flag API, alongside new checked/unchecked and directional gesture events.
lv_label_set_max_lines caps a label at a line count
LV_IMAGE_ALIGN_CONTAIN_DOWNSCALE fits an image without ever scaling it up
Dropdown and Roller now have translation support
The Chinese calendar gained the 24 solar terms
GStreamer now integrates the WebRTC plugin
