Apr 1, 2026April 2026 focused on delivering business-value features for weni-ai/chats-engine, elevating data visibility, user communication, and development operations. Key outcomes include an external endpoint to expose time metrics for finished rooms, refined filtering to exclude deleted/irrelevant data, and unit tests ensuring reliability of bulk actions in the project viewset. Improvements to holiday-closure messaging and email templates reduced user confusion and improved communication. CI/CD and API documentation quality were strengthened with automated PR-title validation and deprecation cleanup in Swagger docs. Changelog and release notes were aligned to reflect new endpoints and templates. These changes collectively improve data quality, user experience, and release readiness across the team.

Mar 1, 2026March 2026 monthly summary for weni-ai/chats-engine. Focus on delivering scalable room lifecycle management, navigation improvements, and automation while ensuring safe feature iteration. Key outcomes include a new soft-delete based room requeue flow with async processing and tests, improved navigation via URL redirection, scalable multi-queue support for repository queries and dashboards, and automation for project updates. Note: a rollback was performed to revert the requeue behavior to prevent unintended reassignment, replacing it with marking affected instances as deleted. This month also included groundwork for internal visibility improvements and tagging optimizations that support maintainability and performance.
