v0.9.0

Added

  • Color depth simulation — 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 UI structure with fewer tokens, so agents work faster and more accurately out of the box

Changed

  • Project Settings modal redesigned with Export, 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 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 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 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 without needing to click away and back

v0.8.2

Fixed

  • Grouped widget assets now preserve group hierarchy during instantiation instead of flattening children
  • New 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 speedometer example template post grouping and font fix

March 8, 2026

v0.8.1

Fixed

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

February 25, 2026

v0.8.0

Fixed

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

Changed

  • Improved security of the backend font conversion pipeline

February 16, 2026

v0.7.0

Added

  • Cross-file copy/paste — widgets now carry their fonts and images when pasted between files
  • Image Fit/Crop mode — resize images proportionally or crop, with matching 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
  • Streamlined context menu with LVGL-relevant actions only
  • Improved performance for background tabs and large project layouts
  • Removed legacy drawing tools (pen, path, curve) to simplify the editor

Fixed

  • Widget drag and scaling no longer behaves erratically during group moves
  • Background color and opacity now clear correctly when toggling styles off
  • Asset panel no longer shows duplicate ghost images

February 14, 2026

v0.6.0

Added

  • PicoPixel is live — open beta launch
  • Visual drag-and-drop LVGL editor with full widget palette
  • Live LVGL simulator powered by WebAssembly
  • Production-ready C code export (LVGL 8.x) with no proprietary dependencies
  • Real-time collaborative editing with live cursors and annotations
  • Built-in version control with session history and rollback
  • Visual events editor for wiring widget interactions without code
  • Reusable assets library for widgets, images, fonts, and colors
  • Shareable simulator links for team and client reviews
  • Custom font management with automatic LVGL conversion

Known Issues

  • Widget animations are not yet supported in the editor or export
  • Events editor flow needs additional testing — some edge cases may not export correctly
  • Minor UI quirks in the property panel under certain widget configurations
