AWS appstream2 medium security documentation change

Service: appstream2 · 2026-04-19 · Security-related medium

File: appstream2/latest/developerguide/base-image-version-history.md

Summary

Removed Amazon Linux 2 from supported operating systems, added end-of-support notice for Amazon Linux 2 images after 04/15/2026, and removed all Amazon Linux 2 version history entries and software component tables.

Security assessment

The change documents the end-of-support timeline for Amazon Linux 2 (AL2) in AppStream, which is a security-related change because unsupported operating systems don't receive security patches, making them vulnerable to exploits. The documentation explicitly states that Amazon Linux 2 images will no longer be available after 04/15/2026 due to End of Support, which is a proactive security measure to prevent customers from using vulnerable, outdated systems.
