Recently shipped Topics trace classification, decision-model evaluator results, and skills imports from files and ZIPs.

**Topics classify and summarize traces.** Traces are now classified into buckets, with an adaptive map exploration view and compact workspace. All facets of a trace summarize in one call, and the summary prompt and default facets were reworked.

**Decision-model evaluators expanded across results, MCP, and OpenAI.** Eval decision model results were revamped, OpenAI decision models are supported, and decision-model evaluators work over MCP. Experiments annotate directly from the comparison grid, with persistent resizable charts and evaluator actions pinned while tables scroll.

**Sessions render as transcripts.** Session view uses trace transcripts, and session tool previews get syntax highlighting. Table rows can use a custom height. Org usage breakdown appears on every deployment, and enterprise SSO remembers the last email on the sign-in form.

**Skills import from local files and ZIPs.** Skills take local file and ZIP imports, unified file and folder uploads, and rendered file previews with raw source access.

**AI gateway adds request correlation.** Resolution context is exposed in response headers, spans, and logs, and a gateway request ID correlates requests. Full-mode inputs capture up to 5 MiB.

**SDK wrap-up.** The Python exporter added opt-in gzip compression (`v4.17.0`). The JS exporter caps oversized batches and stopped serializing each export batch twice; the LangChain integration records completion start time for streamed chat models and no longer reports LangGraph control flow as errors.
