May 1, 2026May 2026 highlights for arthur-engine focused on delivering user-facing data retrieval improvements and stabilizing the CI pipeline. A new LLM Evaluations and Prompts Sorting feature was released, enabling an optional sort_by parameter to sort by name or the latest version creation date, improving data discovery for users. The CI pipeline was stabilized by updating the @tanstack/react-form dependency to address a checksum mismatch, reducing build fragility and speeding up automated installs. These changes collectively strengthen data access for LLM evaluation workflows and improve release readiness.
