24 Commits • 20 Features
Oct 1, 2025October 2025 was focused on delivering value through observability, integration, and security enhancements, while stabilizing platform behavior and improving developer experience. Notable work includes exposing the reasoning behind model decisions in ModelAudit UI, enabling Postman collection imports for the HTTP provider, surfacing GitHub star counts on the site, delivering Snowflake Cortex provider integration, and adding conductor configuration for streamlined deployments. Telemetry instrumentation and red-team event coverage improved observability and incident responsiveness, alongside a significant bug fix to reduce duplicate errors when strategy or plugin IDs are invalid. Documentation updates expanded coverage (safety benchmark, export formats, and index improvements) to accelerate onboarding and self-service. Overall impact: clearer decision support for users, faster integrations, stronger security posture, reduced operational noise, and measurable improvements in developer productivity.
