AWS batch documentation change
Summary
Updated deprecation timeline for Amazon Linux 2 AMIs, specifying end of support date (June 30, 2026), blocking of new environment creation after that date, and emphasizing the risk of running environments without security patches.
Security assessment
The change documents the end-of-life timeline for a specific AMI, which is a planned lifecycle event, not a response to an active security incident. However, it explicitly adds documentation about the security implications of not migrating: environments will 'no longer receive software updates, security patches, or bug fixes from AWS.' This constitutes added security documentation by warning users of future security risks.
