v2.2.1 - Auto-Generated Release (2026-01-01)

What Changed?

This is a patch release created automatically by commitizen during the rebase integration. All Phase 0 work (flag consolidation and conditional compilation removal) has been merged into mainline. The build remains at the same resource utilization as v2.2.0.

What's New

Rebase Integration Complete

What it does: This release integrates Phase 0 work from the development branch into mainline. The rebase successfully merged 34 commits representing the complete flag consolidation refactoring.

How to use it: No changes needed! The build process remains the same:

task v2:build    # Build v2 firmware
task v2:upload   # Upload to ESP32
task monitor     # Verify functionality

Installation

Quick Start

# Get the release
git checkout v2.2.1

# Build v2 firmware
task v2:build

# Upload to ESP32
task v2:upload

# Verify it works
task monitor

Next Steps

Phase 1: Dual-Core Separation (v2.3.0 planned)

With the codebase now unified and simplified, the next major phase will implement multi-threading using FreeRTOS:

  • Separate detection loop (Core 1) from utility operations (Core 2)
  • Eliminate detection loss during serial transmission and command processing
  • Improve timestamp precision from Âą1-2ms to Âą100-500Ξs
  • Target: 10-20x improvement in detection timestamp accuracy
