Version Log

v0.4.0

2026-03-11

Scan Tool: Uploading an image to the Scanner now intelligently displays a preview of the image above the decoded text
Improved rendering performance by optimizing WASM payload configuration (wasm-opt) and allocation strategies
Now uses the modern native BarcodeDetector API for scanning, falling back to a performant WASM-based ZXing decoder
UX: Added smart Z-Index management so active floating panels naturally come to the foreground on click
UX: Uploading a Custom Background image now automatically conceals the Paper layer to guarantee immediate visibility
UX: Advanced Mask Patterns are now labeled with human-readable descriptions rather than mathematical notation
Editor: Removed the redundant 'Layers' panel entirely. Transparency and visibility layers are now fully managed natively within the 'Image' panel
Removed obsolete wee_alloc from WASM crates in favor of the default performant memory allocator
Removed legacy jsqr dependency from the frontend, dropping main-thread execution weight

Current

v0.3.0

2026-02-08

Refined body/eye shapes and improved readability behavior
Toolbar UX upgrades: one-tap export flow, cleaner menu interactions, and better feedback
Added SEO refresh and llms.txt support for better discoverability

v0.2.1

2026-01-22

Implemented strict 5-layer renderer (Card UI base + BG, Paper, Ink, Logo)
Image slots now support BG/Paper/Ink/Logo with transforms + opacity
Rebuilt shapes system (10 body + 10 eye frame + 10 eye ball) with improved icons
Added 'alive' body shapes with neighbor/corner-aware chaining and tuned readability
Fixed verifier: now re-checks on any visual change (including shapes)
Fixed QR scan tool showing '[object Promise]' and improved type dropdown behavior

v0.2.0

2026-01-17

i18n migration + English/Spanish support
SVG export is now real vector SVG (not a PNG embedded in SVG)
Unified wasm-qr-svg loading with a single dynamic loader (removed mixed import warning)
Added JPEG download option and improved export pipeline consistency
Fixed Image panel: logo/background selection no longer mixes images; background + logo can coexist
Improved perceived performance with idle-time WASM prefetch on first user intent

Fixed WebGL shader compilation errors
Resolved 'Outdated Optimize Dep' issues

v0.1.0
