# Workflow authoring and asset upload improvements

**Version:** v2.35.0

**Published:** September 17, 2026

## New Features

- Workflows: Add authoring guidance, definition validation, full definition reads, and deployment tools where Workflows is enabled. Agents can generate workflows from descriptions and deploy new versions while running instances retain their original definition.

## Improvements

- Asset uploads: Add batch status checks and smaller results for asset uploads. Generate `requestKey` automatically when omitted.
- Schema deployments: Register the uploaded schema version as the dataset's authoritative schema.

## Fixes

- `deploy_schema` tool: Reject unsupported `preview` configuration before deployment instead of silently discarding it.
