Full Changelog: v0.2.0-alpha...v0.2.1-alpha

Millefeuille 0.2.0 (alpha)

This update brings enormous performance improvement to auto-updating thumbnails by avoiding GPU readbacks.

✨ New Features

• Full-window resize support - Layers and compositor buffers now automatically track canvas size and pixel density changes when using windowResized() and resizeCanvas()
• Custom layer sizing - New customSize flag protects layers with custom dimensions from auto-resize
• GPU-accelerated thumbnails - Thumbnail capture now uses GPU-to-GPU downsampling, reducing framebuffer readback from ~8MB to ~150KB
• Thumbnail update controls - New options thumbnailAutoUpdate and thumbnailUpdateEvery for configuring automatic thumbnail refresh cadence
• New example - Added full-window resize example demonstrating responsive canvas behavior

🧪 Testing

• Added comprehensive tests for LayerUI thumbnail configuration scenarios
• Added tests for LayerSystem resize behavior

Full Changelog: v0.1.0-alpha...v0.2.0-alpha

Millefeuille 0.1.0 (alpha)

Initial release.

• Photoshop-style layer system for p5.js WebGL, built atop p5.Framebuffer with intuitive layer lifecycle APIs (createLayer, begin/end, render, etc.).
• Layer properties and controls: visibility, opacity, z-index, blend modes, auto-resize, masking with framebuffers or images, plus fluent chaining.
• Compositor overhaul using GLSL blend functions and ping-pong buffers, enabling consistent shader-based compositing across all layers.
• Expanded shader-based blend mode suite using glsl-blend: Normal, Multiply, Screen, Add, Subtract, Overlay, Soft Light, Hard Light, Color Dodge, Color Burn, Darken, Lighten, Difference, Exclusion.
• LayerUI helper and LayerSystem validation to guard against improper WebGL usage, nested begins, and invalid layer references.
• Tutorials and examples (basic layering, blend modes, masking) to showcase common workflows.
• Jest-based test harness with canvas/shader mocks to ensure framebuffer lifecycle, property handling, and compositing logic remain stable.
