December 2024 (MentraOS) delivered key features, reliability improvements, and foundational refactors that broaden multilingual capabilities, streamline third‑party app interactions, and improve audio quality across devices. Major features include a multilingual transcription and translation framework with TPA controls, a unified speech recognition event model with Vosk removal, and initial Even Realities G1 support with corresponding UI flows. Audio processing was enhanced with LC3/RNNoise, BLE microphone integration, and UI stability improvements for text walls. TPA screen management introduced HomeScreenEvent to clear screens on TPA termination, and a project‑wide refactor addressed launch crashes and documentation updates to improve maintainability.
