The August 26 release adds a Model Armor guardrail plugin, SQL injection guards in the BigQuery tools, blocked yaml and ruamel deserialization in agent-config code references, and takes auth from the request rather than the client's response (GitHub). The sub-agent fencing fix is the one to copy: in a multi-agent system, a sub-agent's text arriving at its caller is untrusted content, and most frameworks concatenate it into the caller's context as if it weren't.
