Summarise this release note in one sentence of at most 30 words. Output only the sentence. Release 4.7.0: The public API now enforces a rate limit of 600 requests per minute per key (previously unlimited). Requests over the limit return HTTP 429 with a Retry-After header. Webhook deliveries are now signed with HMAC-SHA256 and the old unsigned mode will be removed in 4.9. We also fixed a bug where exporting more than 10,000 rows produced an empty file.
Rubric for the judge: A single accurate sentence that prioritises the rate limit and signed webhooks; no bullet list, no preamble.
Every cell is one OpenRouter call at temperature 0 with the prompt's token cap and reasoning effort "low" where the model supports it. Cost is usage × the catalogue rate in models.json. Quality is one judge call to anthropic/claude-haiku-4.5 against the prompt's rubric, cached per prompt version.
