It already filtered that list for Amazon Bedrock. It now also removes any beta that appears on a separate exclusion list. When that list is empty, nothing changes.\n\n**Why**\n\nThis gives Claude Code one place to stop particular betas from being requested.\n\n- Area: API\n- Tier: Under the hood\n- Useful: 3\/5\n- Signal: 3\/5"}
