# Changelog (2025-02-17 - 2025-02-18)

## Overview
This release focuses on enhancing the robustness and reliability of the system, particularly in the areas of call session management, speech transcription, text-to-speech (TTS) streaming, and dialing tasks. Key improvements include better error handling, refined control flow logic, and enhanced telemetry capabilities.

## 🚀 New Features
• Enhanced telemetry for TTS tasks by adding vendor-specific metrics, allowing for more granular performance tracking and analysis. This update improves observability and aids in performance optimization decisions. [🔗](https://github.com/quantstruct/jambonz-feature-server/commit/33bca8e67c8f29bd86558f2831e8fb80b5074c1f)

## 🐛 Bug Fixes
• Improved handling of speech transcription in the `TaskGather` class, addressing issues with the Speechmatics vendor to prevent premature termination of the listening process. [🔗](https://github.com/quantstruct/jambonz-feature-server/commit/122d267816879fb515d128522e44aef50a1641c9)

## ⚡ Performance Improvements
• Refactored the `TtsStreamingBuffer` class to replace the token-based system with a structured queue system, enhancing the management of text chunks and flush commands. This change improves the accuracy and reliability of TTS streaming. [🔗](https://github.com/quantstruct/jambonz-feature-server/commit/122d267816879fb515d128522e44aef50a1641c9)

## 🔧 Maintenance
• Wrapped the `updateCall` method logic in a `try-catch` block to improve error handling and prevent application crashes, enhancing the robustness of call session management. [🔗](https://github.com/quantstruct/jambonz-feature-server/commit/e8a7366526bc1db785f809875281766d938a892a)

• Updated error handling and control flow logic in the `TaskDial` class to ensure execution aligns with expected operational states, reducing the risk of unintended behavior during media playback.
