v2.1.1

• Fix installation issue

v2.1.0

• Added support for using a RP2040 microcontroller board (Raspberry Pi Pico) connected via USB to any computer to control LEDs
  • No Raspberry Pi single-board computer required
  • All RP2040 microcontroller boards should work
  • Both RGBW and RGB LED strips supported
  • Linux and Windows hosts are supported
• Added support for Apple HomeKit (experimental)

v2.0.0

• Web interface completely rewritten under the hood to use Vue 3
  • Color temperature, sACN, and other less-frequently-used controls moved to a separate page
  • Color correction is now configured via the web UI instead of command-line arguments
  • Added UI to save, load, and delete presets (#31)
  • Added a 'calibration mode' control which displays RGBW(255, 255, 255, 0) on all LEDs to assist in setting color correction
  • Added a toggle to show previews of all color palettes
  • Removed unnecessary font files from the web UI
  • Switched to a much faster web server to reduce CPU and memory overhead
• Added Groups to use different settings, animations, and color palettes on subsets of LEDs (see #27 for more info)
• Added many new color palettes and improved or redesigned all existing ones
• Added new animation patterns: Twinkle Gradient, Twinkle White, Palette Cycle Wipe, Palette Cycle Wipe From Center, Palette fBm Noise
• Added a command line argument to specify a different location for the config file
• Updated dependencies to latest versions (Flask, RestrictedPython, CodeMirror)

Breaking changes:

• New config file structure - files from previous versions will be automatically upgraded and a backup will be created
• Completely changed the API used by the web interface - the getfps and resettimer endpoints are not affected
• Removed secondary animation patterns - all functionality here has either already been added to built-in animations or would be trivial to implement if desired
• Speed and scale are no longer saved with each animation pattern - the speed of the built-in animations is much more consistent now than when this feature was added and if this functionality is still needed it can be achieved with presets

Known issues:

• Sometimes, when using the new web server, atexit handlers will not be called and recent changes to the config file will not be saved when exiting the program with Ctrl+C

v1.4.0

• Updated rpi_ws281x submodule to support Raspberry Pi Zero 2
• Added 3 new color palettes
• Added static white animation pattern
• Fixed a bug with HSV color palette interpolation
• Animation timer now resets when pattern is changed

v1.3.0

• E1.31 sACN receiver mode - allows low-latency direct control of LEDs over the network and enables music visualization through LedFx and other control software
  
• Support for custom pixel mappings - for displaying animations on arbitrary 2D and 3D LED arrangements
• Pattern functions now receive 3D position instead of 2D - existing custom patterns will be upgraded automatically
• Improved performance and default speed settings for some built-in animation patterns
• Added palette_mirrored utility function
• Added animated GIF previews of all built-in animations to patterns.md
• Fix more minor issues with web interface

v1.2.0

• 12 all new built-in color palettes
• Added a preview of the current color palette in the web interface
• New animation patterns, including Plasma and Perlin Noise animations that work with color palettes:
  • Static Gradient Mirrored 1D
  • Palette Scan/Bounce Mirrored 1D - replaces Palette Bounce 1D
  • Palette Ripples (Fast Cycle) 1D - alternate version of Palette Ripples 1D
  • Palette Plasma 2D
  • Palette Fractal Plasma 2D
  • Palette Perlin Noise 2D
• Improvements to consistency and appearance of existing animation patterns
• Added fast fBm (fractal Brownian motion) noise utility function for use in animations
• Fix minor issues with web interface and LEDs not updating when values are changed
• Minor performance improvements

v1.1.2

Remove dependency on recordclass, fix install issue

v1.1.1

Fix issue with LEDs not updating when palette colors are changed in some modes

v1.1.0

• Greatly improved rendering of desaturated colors
• Performance improvements
• Allow pixel order command line argument to be in lowercase
• Fix minor issues with web interface

v1.0.0

(v1.0 release since this is stable and the installation issues seem to have been resolved)
