Anthropic has released Claude Code 2.1.172, a significant update that allows subagents to spawn their own subagents, creating a nested structure up to five levels deep. This new capability enables more complex task delegation, such as breaking down large code reviews or migrations into smaller, manageable pieces distributed across multiple agents. The update also includes improvements to plugin searching and a fix for sessions exceeding the 1 million context window limit, along with adjustments for Amazon Bedrock users regarding AWS region configuration.
