Mar 1, 2026March 2026: Reliability and data integrity improvements for the elevenlabs/packages repo. Delivered Wix integration stability by guarding the non-writable addEventListener at runtime and applying the livekit-client patch via patchedDependencies, ensuring patches are included in npm/pnpm publishes. Refined transcript handling to preserve text messages while stripping audio tags only from voice transcripts, with tests updated to reflect the new behavior. These changes reduce runtime crashes on Wix sites, improve transcript fidelity, and strengthen patch deployment practices. Technologies include JavaScript/TypeScript, pnpm patching, try-catch guards, and test-driven validation.

Feb 1, 2026February 2026 (2026-02) highlights business value through delivered features, reliability fixes, and UX enhancements for elevenlabs/packages. Key work centers on making TTS outputs clearer, improving tool-call transparency, and enabling flexible ConvAIWidget configuration. Notable deliveries and fixes include: - Text-to-Speech Emotion Tag Stripping: added a configurable stripAudioTags option with a safer regex and comprehensive integration tests to prevent stripping markdown links. - Widget: Tool Call Status Display and Inline Transcript Tracking: implemented real-time agent status during tool calls and per-event transcript entries via event_id, supported by status refactors and UI tweaks. - ConvAIWidget UX Enhancements: introduced PlaygroundSettings, a show-conversation-id option for disconnection messages, and a Safari rendering fix by unwrapping @supports blocks in the Tailwind/CSS pipeline. - Stability, tests, and refactors: improvements to transcript handling, CSS/layout adjustments, and test coverage across features, with related changesets. Impact: clearer TTS outputs, more transparent tool interactions, configurable widget behavior, and cross-browser consistency, reducing support load and accelerating feature adoption. Technologies/skills demonstrated: regex hardening, integration testing, type-safe configuration (WidgetConfig), inline transcript architecture, event_id propagation, DOM/CSS tweaks in Shadow DOM, and cross-browser rendering fixes.

Jan 1, 2026January 2026 (2026-01) delivered a redesigned Agent Widget with markdown rendering improvements, a text/voice mode toggle, dark mode, and allowlist-controlled link rendering, significantly improving agent usability and governance. The team fixed critical UI/UX issues (multiline user message rendering) and chat reliability (microphone mute state reset on call end). Frontend modernization included Tailwind CSS v4 upgrade, Node.js 22 CI alignment, and a Shadow DOM styling workflow via a Vite plugin to ensure consistent visuals inside shadow roots. The work also enhanced performance and maintainability through refactors, updated package versions (convai-widget-core/convai-widget-embed to 0.6.1), and added markdown rendering tests.
