🚀 v2.2.0 (Latest Stable)

🌟 New Features & Enhancements

• Native C++ Telematics Vault:
  • Core GPS verification, EMA algorithms, and JWT license parsing are now executed inside an obfuscated C++ .so vault (libveg_vault.so) to prevent Dalvik/ART hooking.
• Flexible Commercial Licensing:
  • Completely replaced Firebase authentication with offline-first JWT (JSON Web Token) commercial license keys that encode module access and expiry dates directly in the payload.
• Sample Applications Monorepo:
  • Released the veg-sahayyak-samples repository featuring 6 B2B integrations (Basic, Fleet, UBI, Background, Custom UI, OEM).

🟡 v2.1.0 (Legacy Stable)

🌟 New Features & Enhancements

• Voice Commands & Driving Profiles:
  • Introduced VoiceCommandButton and VoiceCommandParser for hands-free mode switching.
  • Replaced manual limit configuration with legal DrivingProfile bounds (e.g. CarHighway, SchoolZone).
• Client Theme & Color Scheme Injection:
  • Added SpeedColorScheme (:speed-core) and SpeedUiColorScheme (:speed-ui) allowing host apps to inject custom brand colors.
  • Propagates brand colors across SpeedGauge, HudDisplay, PipWidget, and foreground NotificationProvider.
• HUD Windshield Reflection Mode:
  • Added Modifier.hudMirror() for vertical/horizontal axis transformations.
  • Added HudDisplay standalone composable with true OLED black (#000000) background and high-visibility 120sp typography.
  • Integrated HUD mirroring into SpeedGauge and ThemeMode.HUD_MIRRORED.
• Decoupled Architecture Modules:
  • :speed-overlay: Standalone floating Picture-in-Picture speedometer widget (PipWidget).
  • :speed-autostart: Zero-touch background trip detection via Google Play Activity Recognition (AutoStartManager).

🐛 Bug Fixes

• False Minimum Speed Alarms: Implemented 8 km/h Stationary Suppression in TelematicsEngine. The under-speed alarm is now aggressively silenced when the vehicle is in heavy traffic or navigating speed bumps.

• API 25 Crash Fix: Resolved VectorDrawable inflation crashes on Android Nougat (API 25).

• AAPT2 String Errors: Fixed missing localized string resources triggering AAPT2 compilation failures during :app assembly.

• CI/CD Quality Gates & Coverage:

  • Aggregated multi-module JaCoCo coverage reporting (jacoco.gradle.kts).
  • Verified full ProGuard consumer rules and zero-warning Lint passes.

🚀 v2.0.2

🌟 New Features & Enhancements

• TelematicsEngine Signal Pipeline:
  • Implemented Exponential Moving Average (EMA) with [REDACTED] smoothing to eliminate jitter from raw GPS sensor readings.
  • Added confidence gating to automatically discard GPS fixes exceeding [C++ VAULT THRESHOLD] inaccuracy.
  • Introduced Dual Schmitt Trigger Hysteresis (+1.0 km/h alert, -3.0 km/h dismissal) to prevent alarm fluttering.
• Jetpack Compose UI Gallery (:speed-ui):
  • Added hardware-accelerated SpeedGauge canvas component with smooth 60fps needle animations.
  • Added high-contrast and OLED dark theme presets.
  • Integrated real-time GPS accuracy pill badge (Good, Fair, Weak).
• Bill of Materials (:speed-bom):
  • Added Gradle platform BOM artifact for aligned SDK dependency resolution.

🔄 Migration Guide: v1.x → v2.0.x

Version 2.0 represents a major architectural overhaul, splitting the codebase into modular SDK components:

1. Update Gradle Dependencies

Replace legacy monolithic imports with the modular BOM:

// Old (v1.x)
implementation("com.vegsahayyak:speed-assistant:1.2.0")

// New (v2.x Modular)
implementation(platform("com.vegsahayyak:speed-bom:2.0.2"))
implementation("com.vegsahayyak:speed-core")
implementation("com.vegsahayyak:speed-ui")

2. Update Initialization Pattern

Replace static singleton access with the manual service locator builder:

// Old (v1.x)
SpeedAssistantManager.getInstance().start(context)

// New (v2.x)
SpeedAssistant.with(context, "YOUR_JWT_LICENSE")
    .setDrivingProfile(DrivingProfile.CarHighway)
    .start()

🔮 Upcoming: v2.3.0 Roadmap Teaser

The upcoming v2.3.0 release will introduce further enterprise telematics and driver safety capabilities:

• Trip Reports & Export (PDF/CSV): Comprehensive driving logs, trip summaries, and compliance reports for parents and fleet managers.
• Emergency SOS on Sudden Deceleration: Life-saving automated first-responder triggers on severe decelerations.
• Lock Settings While Monitoring: Vibration-proof dashboard lock preventing accidental setting modifications during active monitoring.
• Intent-Based Telematics: On-device LLM / Gemini Nano integration for conversational driving profile switching.
