FW 0.12.11\_20260415

Spectoda Firmware v0.12.11_20260415 Release Notes

Release Date: April 15, 2026
Version: 0.12.11_20260415
Base Tag: v0.12.11

🚀 Major Features

• Added a staged rev0-to-rev1 OTA partition migration flow with config backup and restore, app relocation, partition table rewrite, and revision-aware post-OTA handling.
• Hardened peer-to-peer OTA compatibility by advertising fw_max_image_size and rejecting incompatible firmware transfers earlier.
• Added a generic I2C IO path for Berry scripting and expanded I2C-based integration support.
• Added new I2C example scripts for Daylight, Skylight, VEML7700, MPU6050, LSM6DS3TR, and MPR121.
• Expanded WebAssembly support with network write requests, richer synchronization snapshots, and analytics record blob generation.

🔧 Technical Improvements & Refactors

• Exposed system revision through controller info and OTA helpers for more reliable diagnostics and revision-aware upgrade logic.
• Improved serial communication pacing, large-payload handling, and forwarded request/sync arbitration.
• Added the ability to change ESP-NOW power and datarate from Berry.
• Restored loading of config-defined Berry plugins after boot and TNGL reload.
• Performed a major firmware repository cleanup across ESP32, WASM, tooling, artifacts, and public header layout.

📈 Performance & Stability

• Improved serial throughput and stability under heavy traffic.
• Made mixed rev0/rev1 peer OTA rollouts safer by aligning sync logic with the active OTA geometry.
• Added rev1-targeted Berry and I2C smoke workflows for faster validation of scripting and sensor integrations.
• Added stronger build-time validation for OTA slot sizing and SPECTODA log code consistency.

🐛 Bug Fixes

• Fixed serial mutex starvation and ownership issues during forwarded request traffic.
• Fixed large serial payload handling and reduced noisy warning spam during retry scenarios.
• Fixed compatibility handling for legacy peers during peer-to-peer firmware OTA.
• Removed deprecated dedicated VEML7700 and APDS9930 integration paths in favor of the generic I2C flow.

🧩 Compatibility & Migration Notes

• No broad migration is required for existing 0.12.11 installations.
• Legacy rev0 controllers now have a dedicated migration path to newer OTA geometry.
• Mixed rev0/rev1 networks are handled more safely, but rev0 controllers still have tighter OTA size limits.
• Custom scripts using older dedicated sensor helpers should be updated to the generic io["I2C"] model.
