During January 2026, Sibbl enhanced the openclaw/openclaw repository by upgrading its Matrix extension to use matrix-bot-sdk with end-to-end encryption, improving both security and alignment with Matrix core concepts. Sibbl expanded media handling to support voice messages and image attachments, including metadata and thumbnails, enabling richer user interactions. The work involved refactoring legacy code, normalizing thread IDs to resolve message sending failures, and strengthening direct messaging workflows with robust error handling. Using TypeScript and Node.js, Sibbl focused on backend development and API integration, delivering deeper reliability and maintainability for Matrix-based communications through targeted feature delivery and thoughtful code cleanup.
