## Overview

Sessions, AI metadata depth, and experiment tooling headline the latest Inngest releases.

**Sessions shipped as a first-class primitive.** Server-side session parse and emit landed in v1.31.0 alongside a dashboard UI; event payloads in the JS SDK gained a `sessions` field in v4.7.0; the invoke button now accepts session context; and v1.35.0 added REST V2 endpoints (`GET /v2/sessions` and `GET /v2/sessions/{key}/{id}/runs`) for programmatic session queries.

**AI step observability expanded across SDKs.** The JS SDK now extracts model, provider, response ID, token counts, finish reasons, and operation names from OTel GenAI spans — with an opt-out flag in v4.8.0. Server-side AI Metadata fields were renamed in v1.36.0: `.model` → `.request_model` and `.system` → `.provider` to align with OpenTelemetry GenAI standards. `@inngest/otel` added CommonJS and Google AI support in v0.2.0.

**Experiments gained a REST API and richer charts.** v1.35.0 added `GET /v2/experiments` and per-function experiment endpoints to the REST V2 API, plus box-plot charts for visualizing numeric metrics.

**Rerun from step now works in the cloud.** Previously dev-server only, the feature shipped in v1.34.0 for all step types, including the ability to update step inputs before rerunning.

**SvelteKit serve handlers added streaming.** JS SDK v4.12.0 added streaming support to SvelteKit serve handlers and fixed a hang on parallel steps when `optimizeParallelism` is off.
