v0.8

New Features

• SPI Bus Selection: Added ethSpiBus configuration to select between SPI2 and SPI3 for Ethernet (when supported by hardware) (#241)
  • New Web UI note component warns users about GPIO conflicts when using Ethernet and PN532 on the same SPI bus
  • Automatic separation of Ethernet and PN532 SPI buses when SPI3 available
• Auth Precompute Cache: Added optional authentication context precomputation for faster HomeKey taps (#224)
  • Enable/disable through the UI (Misc -> HomeKey -> Auth Precompute Cache) or through API via hkAuthPrecomputeEnabled
  • Background task manages cache of precomputed authentication contexts
  • Intelligent cache invalidation when reader data changes
  • Significant performance improvement for repeated taps

Fixes and Improvements

• Logging System: Integrated loggable framework for unified, configurable logging across components
• Memory Safety: Added mutex protection for reader data concurrent access in ReaderDataManager (#224)
• Thread-Safe Snapshots: New getReaderDataCopy() method provides safe reader data snapshots (#224)
• Configuration Validation: Enhanced SPI bus validation and error messages in Web UI (#241)
• Build System: Improved find command compatibility in CMakeLists (#247)
• Stability: Fixed various race conditions and memory safety issues
• HomeKey Issues: Fixed HomeKey authentication issues that prevented Apple Watch and other secondary devices from unlocking the device (fixed #215)
• Web UI Reliability: Enhanced Web UI responsiveness and availability (fixed #237) (fixes? #211)
• Persistence issue: Fixed config deserialization for the neopixel colors (fixed #249)
• Improved OTA: Refactored OTA update process for better stability and cleaner code (#233)

Internal Changes

• Event System Overhaul: Completely refactored event handling from the espp::EventManager to a custom EventBus system for more efficient and flexible event communication (#229)
• Component Updates: Replaced espp/event_manager with esp32-event-bus, this is a simpler implementation that only uses one task and one queue which hugely decreased memory consumption and fixed exhaustion on lower memory models like C3
• New PN532 driver architecture: Migrated from PN532 library to modular pn532_cxx, esp-hal-pn532(Platform HAL) to house platform-agnostic support for future projects and this also motivated me to improve error handling and logging on both the application and transport layer.
• Console Logging: New ConsoleLogSinker provides ANSI colored console output with a cohesive and easily readable format between esp_log logs and loggable logs (used to dispatch logs to mutliple sinks, such as WebSocket to display them on the UI)

Build & CI Improvements

• Nix Flake Update: Updated to nixos-25.11 and switched to mirrexagon/nixpkgs-esp-dev
• LittleFS Handling: Improved LittleFS remounting during OTA updates
• Component Management: Updated to latest library versions

Documentation Updates

• Contributing Guidelines: Added some basic AI/LLM usage guidelines for contributions
• Configuration Guide: Added documentation for new auth cache option and Ethernet SPI bus selection
