v0.11.0

Added

  • Animated image widget — build looping image animations from a set of frames, with playback controls, a frame picker, and the option to save reusable animation sets to your library
  • Sprite widget — multi-phase animations where each phase has its own frames, timing, and repeat settings, perfect for game-style characters and pets that switch between states
  • Event actions for animations and sprites — start, stop, restart, or switch phases in response to button presses, sensors, or your own firmware triggers, with everything carried through to the exported C code
  • Custom Event triggers — fire animations, screen changes, and other actions straight from your device's code (servo callbacks, sensor thresholds, custom logic), with ready-made helper functions in the export
  • Round display support — switch a screen between standard and circular shapes in Project Settings, with the round look applied in the editor, simulator, dashboard thumbnails, and export
  • Submit a Sprite or Template — new settings pages to share your creations with the community, plus links to a submission guide
  • Community templates can now be opened directly in PicoPixel from a shareable link
  • Per-widget anti-aliasing and locked aspect-ratio controls for sharper, proportionally-scaled images, animations, and sprites
  • Stronger account security — automatic lockout after repeated failed logins, early warnings before lockout, and protections against bots and spam sign-ups
  • "Create an account" and "Already have an account?" links added to the login and register pages, plus clearer messaging when an account is temporarily locked
  • Higher capacity — projects can now hold up to 128 images (previously 64)
  • Choose your LVGL include style in Project Settings so the exported C code matches your platform's conventions

Changed

  • "Work email" is now simply "Email" everywhere, and the newsletter checkbox was removed from sign-up
  • "Project/Projects" and "Workspace/Workspaces" labels were swapped across the app, and saved "Widgets" are now called "Components" everywhere for clearer naming
  • Screen limit raised to 500 and the usage meter removed, so large projects no longer hit a wall
  • New widgets now appear on the canvas instantly instead of after a short delay
  • Settings sidebar tidied up with a Discord feedback link, cleaner section dividers, and updated guide links
  • Exported project documentation renamed to a cleaner README.md and expanded to cover animations, sprites, and round displays
  • Faster, more reliable loading of fonts and graphics in production
  • Translations expanded and synced across many more languages, including Brazilian Portuguese, Russian, Italian, Hindi, Indonesian, Ukrainian, Czech, Arabic, and more

Fixed

  • Animated images and sprites no longer tile, show black borders, or display gray boxes when scaled or left empty — they now zoom to fit and show a clear placeholder
  • Fixed a range of crashes when deleting screens, duplicating files near the storage limit, removing the last widget property, or viewing default styles on image and animation widgets
  • Animations now play back cleanly without leftover timers, stale frames, or stacked previews carrying over between sessions
  • Animation colors now render correctly on hardware that uses swapped color formats
  • Round displays now apply correctly in the simulator, dashboard thumbnails, and exported code
  • Pasting a screen now places it correctly at the top level instead of nesting it inside another screen
  • Exported images no longer tile when their proportions differ from the widget

v0.10.0

Added

  • Animation mode with a full timeline for creating, editing, previewing, and saving LVGL widget animations
  • Keyframes for position, size, and opacity, with timeline scrubbing, easing paths, loop/once playback, editable timing, and event actions that can play animations in previews and exported LVGL projects
  • Workspace activity console for watching widget, font, event, and export activity while building embedded LVGL GUI projects
  • Bundled font picker with curated fonts, live previews, font weights, multi-size presets, and guided controls for non-Latin and Asian-language text
  • New Animation, Fonts, and Events example templates for LVGL GUI builder projects, with refreshed dashboard thumbnails

Changed

  • Build, Design, and Animation modes are now separated more clearly in the LVGL GUI editor, so animation work stays out of normal design editing
  • The sidebar now has always-visible Layer controls, rotation and pivot controls, and inline Label text styling for faster LVGL GUI editor workflows
  • Font creation now supports many more languages and writing systems, including Arabic, Hebrew, Thai, Greek, Cyrillic, Devanagari, Bengali, Vietnamese, Chinese, Japanese, and Korean
  • Font uploads now give clearer help when a file cannot be converted and handle larger multilingual fonts more reliably
  • LVGL C exports now better match the GUI editor preview for animations, image fitting, event actions, custom font symbols, and right-to-left text
  • Events now preserve more interaction settings across preview, import, and export, including property changes and animation playback actions
  • Workspace limits are now checked before template imports, library imports, duplicates, and drag-and-drop imports, with clearer warnings when a project is at capacity

Fixed

  • Animation previews no longer leak animated positions, sizes, or opacity back into design mode
  • Rotated and animated widgets now keep selection outlines, handles, measurements, and canvas rendering aligned
  • Widget movement and resizing now snap more accurately to the pixel grid, reducing small visual offsets after edits
  • LVGL viewer previews now restart more cleanly so events and animations can replay without stale screen state
  • Imported images, portable PicoPixel templates, bundled fonts, and newly created fonts now relink and apply more reliably
  • Label Fill/Text controls and default design-mode text color were restored where they had gone missing

v0.9.0

Added

  • Color depth simulation for LVGL GUI editor projects — select 16-bit, 16 sw-bit, or 8-bit in Project Settings to live-preview quantized colors matching your target hardware
  • LVGL events now support calling named functions directly in the simulator
  • AI context file included in every LVGL export — a concise project summary that helps AI coding assistants understand your embedded UI structure with fewer tokens, so agents work faster and more accurately out of the box

Changed

  • Project Settings modal redesigned with LVGL export controls, share actions, and a usage sidebar
  • Export button restyled and renamed to "Export LVGL UI"
  • Default dashboard tab is now Drafts instead of Projects
  • Image asset previews show a checkerboard background for transparent PNGs
  • Screen resolution changes now instantly re-render the LVGL GUI editor canvas without a page refresh
  • LVGL export ZIP renamed to picopixel_lvgl_ui.zip to avoid confusion with other tools

Removed

  • Legacy design sidebar panels for non-LVGL shapes — right panel now shows only layer controls and dimensions

Fixed

  • Background images on LVGL panels, containers, and buttons now export and render correctly
  • LVGL events overhaul — Set Opacity, Set Text, Set Properties, Set State, Modify Flag, and Call Function actions now fire correctly in Play mode and export working C callbacks
  • Click and input events now work on all LVGL widget types, not just buttons
  • Image assets from shared libraries now clone into the current file, preventing broken references
  • Asset library images display correctly in the sidebar after importing a .picopixel file
  • Custom fonts apply immediately in the LVGL GUI editor without needing to click away and back

March 25, 2026

v0.8.2

Fixed

  • Grouped LVGL widget assets now preserve group hierarchy during instantiation instead of flattening children
  • New LVGL widget name counter increments from current highest number rather than reusing last created index
  • LVGL widget assets no longer require a page refresh to render after memory allocation during init

Changed

  • Update the LVGL speedometer example template after grouping and font fixes

March 8, 2026

v0.8.1

Fixed

  • Resolved an issue where LVGL widgets placed inside an LVGL GUI editor canvas group could sometimes be missing from the exported C code
  • The preview panel now correctly detects LVGL widgets nested within non-LVGL objects on the LVGL GUI editor canvas

February 25, 2026

v0.8.0

Fixed

  • Custom LVGL font export now produces correct, standalone C source files — previously exported fonts could fail to compile or load at runtime
  • Font identifiers in generated LVGL code are now guaranteed to be valid C names, preventing build errors with certain font names
  • Fonts created in the LVGL GUI editor before this fix now show a clear warning during export and gracefully fall back to the default font

Changed

February 16, 2026

v0.7.0

Added

  • Image Fit/Crop mode — resize images proportionally or crop, with matching LVGL C code export
  • LVGL groups can now be freely moved within screen hierarchies
  • Library fonts are now available across all workspaces

Changed

  • New branded loading animation replaces the previous splash screen loader
