Design Studio for FastLED 0.7.0

Highlights

• Add HUB75 as a first-class MatrixOutput hardware family for ESP32, ESP32-S2, and ESP32-S3, including single panels, chained rows, folded and serpentine grids, rotations, and all firmware generators.
• Add a dedicated HUB75 Topology mode to Flash Wiring Test, with unmistakable per-panel coordinate and orientation markers for validating 2D panel layouts.
• Improve preview/firmware palette parity, palette-aware RAM estimates, and the RAM calibration harness.
• Add ten curated featured patterns, fix silent first frames in live-audio recording, update fbuild to 2.5.15, and move CI actions to the Node 24 runtime.

HUB75 hardware status

Single-panel 64×64 HUB75 upload and wiring diagnostics have recorded hardware validation. Multi-panel chains, folded/rotated layouts, streaming, show playback, and music-sync remain experimental pending broader hardware validation.

Desktop archives are available for Windows x64, Linux x64, macOS Apple Silicon, and macOS Intel. Verify downloads with SHA256SUMS.txt.

Design Studio for FastLED v0.4.0

Design Studio for FastLED v0.4.0

This beta release is a substantial authoring, performance, hardware-workflow, and reliability update over v0.3.0.

Highlights

• Performance Deck: pin graph properties as large knobs, faders, toggles, or selectors; save and recall parameter scenes; morph between scenes; and learn MIDI or keyboard bindings.
• Project and pattern workflows: named autosaved projects, recovery snapshots, safer disk sync, improved Pattern Collections, and offline Pattern Ratings for saved and bundled patterns.
• Hardware authoring: multiple independent Matrix Output routes, board-aware GPIO guidance, a streamlined setup wizard, Graph Health diagnostics, flash/RAM capacity checks, and opt-in beta hardware reports.
• New creative tools: 3D Wireframe with custom-mesh decimation, Palette from Image, preview recording to PNG/GIF/WebM, expanded Ease and node controls, resizable panels, and refreshed starters/help.
• Clock and live-control inputs: RTC Clock, Clock Display, Schedule Trigger, NTP, DS3231, and DMX/Art-Net authoring and firmware paths.
• Reliability: sustained-streaming fixes, music-sync SD provisioning/player corrections, safer project persistence, undo/history fixes, codegen corrections, and numerous interaction/performance fixes.
• Security: Wi-Fi credentials no longer travel in projects or share links, and both the production and full npm audits report zero known advisories.

Support scope

The public-beta support promise remains deliberately narrow. Only the exact environments recorded in the beta support matrix are supported end to end.

RTC/NTP, DS3231, DMX/Art-Net, PSRAM, tiled/custom layouts, and music-sync SD provisioning remain experimental until their outstanding hardware-validation runs are recorded.

Desktop archives

The attached Windows x64, Linux x64, macOS ARM64, and macOS Intel portable archives were built and launch-smoked on clean GitHub-hosted runners. SHA256SUMS.txt contains their checksums.

These archives are unsigned experimental beta artifacts. They have not completed Authenticode signing, macOS signing/notarization, or clean end-user-account hardware-upload validation and must not yet be described as supported desktop packages.

Verification

• Main CI and backend tests
• Cross-platform dependency compatibility
• Tagged four-platform desktop packaging
• Curated changelog
