AWS bedrock-agentcore documentation change
Summary
Added 'Adjustable' column to memory limits table and updated limit values/descriptions
Security assessment
The changes clarify which service limits can be adjusted via Service Quotas and update API rate limits (e.g., increasing CreateEvent requests from 5 to 10 TPS). While rate limits can indirectly impact security by preventing abuse, there is no explicit evidence of a security vulnerability being addressed or new security features being documented. The updates are operational in nature.
