Version Control Freak

TGIF! Thank god it’s features, here’s what we shipped this week:

Datasets just got serious with Dataset Versioning—every change tracked, every version referenceable, no more “which dataset did we eval against?” Meanwhile, Replay Trace in Arena lets you re-run any production trace through Arena to compare models side-by-side on real traffic. And for the compliance-minded: Audit Logs are here.

Changelog March 14, 2026

Added

  • Dataset Versioning - Datasets now have full version history. Every edit, every addition tracked—so you always know exactly what you evaluated against. No more version of events that doesn’t add up.
  • Replay Trace in Arena - Take any production trace and replay it in Arena. Compare how different models handle the same real-world input, side by side. It’s the replay value you’ve been waiting for.
  • Audit Logs - Full visibility into who did what, and when. Every action logged, every change accounted for. Your compliance team just breathed a sigh of relief.
