101 Commits • 32 Features
Apr 1, 2026During April 2026, the team delivered substantial business value through feature improvements, reliability fixes, and expanded test coverage across promptfoo/promptfoo. Key features shipped include multimodal input support for OpenAI provider agents, expanded Codex SDK evaluation controls and documentation, Codex local images support with SDK hardening, and a new Web UI system theme selector. In addition, testing, quality, and infrastructure were significantly enhanced with broader coverage across cache, redteam, and web UI, plus faster redteam test suites and improved test hygiene. Major bugs fixed encompassed CLI source-map initialization, MCP value handling (preserving falsy values and correct truncation), login org flag support, provider omitDefaults alignment, token refresh deduplication, redteam env-file parsing and concurrency config, assertions normalization, and UI timer/feedback improvements. Overall this work improves reliability, security, and developer productivity, while expanding automation capabilities and reducing regression risk.
