+## What's new

+- Lowered the maximum batch size from 2000 to 200 results per request, matching the new bulk-results API cap. `BatchConfig.set_size` now rejects a size above 200, and both TestOps reporters clamp the configured size with `min(200, ...)`. The default stays 200, so setups on defaults are unaffected.
