Sep 1, 2025September 2025 monthly summary for signalwire/signalwire-js: Delivered Video SDK CI testing and debugging enhancements with refactoring for reliability and observability across stream checks, room management, and logging. Core improvements included modularizing the CI pipeline by dividing the call fabric into sub-projects, employing soft assertions, and polling-based checks; removing e2e-client tests to streamline the pipeline; and expanding test coverage by adding explicit steps in room session and member handling specs. The changes improved CI stability, reduced debugging time, and increased release confidence.

Jun 1, 2025June 2025: Delivered two major features in signalwire-js with measurable business impact and improved stability. Robust GitHub Playground Deployments: refactored the bash script for uploading GitHub playground builds, enhanced branch filtering, strengthened error handling across SDK and playground builds, and updated the GitHub Pages deployment action to the latest version to provide reliable, branch-specific playground deployments. CallFabric SDK Microphone Features: introduced microphone APIs and tests to manage audio flags (echo cancellation, auto gain, noise suppression) for self and other members; updated end-to-end tests and internal client logic to support these configurations. In addition, fixed the GitHub playground upload script to improve reliability and branch handling, and kept CI/CD tooling up to date.

May 1, 2025May 2025: Delivered two core features in signalwire-js with cross-cutting impact on call reliability, attribution, and developer UX. Implemented Default Media Parameters in the Call Flow SDK and added From Fabric Address ID support across the CF SDK and Playground UI. Created testing/documentation assets and enhanced UI persistence to ensure consistent parameter usage across sessions. These changes reduce configuration errors, improve attribution telemetry, and accelerate integration for customers using Fabric-address-based workflows.

Mar 1, 2025March 2025 focused on enhancing call control UX, stabilizing realtime communications, and ensuring release readiness for signalwire-js. Key features delivered include new hold/unhold APIs for CallFabric and Video SDKs, and reliability improvements for realtime messaging. Release prep for the March 4, 2025 launch was completed with comprehensive changelogs across packages and inclusion of package-lock.json. Realtime API robustness was further improved with auto-resubscription of voice call topics after socket reconnects, chat API type fixes, and BaseNamespace unit tests. These efforts collectively improve user experience in live sessions, reduce post-reconnect disruptions, and strengthen CI/test coverage for more deterministic deployments.
