This beta introduces AI-assisted evaluator generation, scoring improvements, and expanded SQL querying capabilities alongside timeline visualization enhancements and better trace metadata.

Features & Enhancements#

  • Server Stability — Improved handling of malformed spans and OTLP int64 values to prevent ingestion errors.
  • OpenAI Compatibility — Added support for max_completion_tokens parameter used by newer OpenAI models.
  • UI Fixes — Fixed drawer closing behavior, span deletion refresh, auth URL browser link handling, and time range persistence across views.
