What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

- **fixed** — Preserve active text and reasoning parts when another merged UI message stream finishes a step, and align workflow stream normalization with the explicit part end chunks
- **added** — Add batch completion webhooks where experimental_startTextBatch accepts a webhookUrl, and the gateway provider registers it through the batch callbackUrl contract and exports typed async-job metadata
- **changed** — Direct Anthropic and OpenAI batch providers return an unsupported warning when the webhookUrl option is provided
- **fixed** — Parse structured generateText output when providers omit finishReason but return text
