- Breaking changes: removal of unused ClickHouse feature gates and UI changes such as opening JSON views from the v3 trace API and migrating downloads to the new client.
- New features added across query, storage, and UI layers, including SQL statement support, API v3 search over HTTP/GRPC, AI auth gating, streamable HTTP transport, lazy‑loading of large attributes, and in‑browser OTLP trace parsing.
- Extensive documentation updates (remote storage gRPC port, security threat model, release process, RFCs) and numerous bug fixes and refactorings throughout the backend and UI.
