AWS managedservices documentation change

Service: managedservices · 2026-05-01 · Documentation low

File: managedservices/latest/ctref/doc-history-ct.md

Summary

Added documentation for EBS volume parameter limit updates and deprecated Outbound (Palo Alto) change types, plus removed hyperlinks from older change type references

Security assessment

The changes include: 1) Updated EBS volume parameter limits (performance-related, not security), 2) Deprecated Palo Alto firewall change types (likely service deprecation, not a security fix), and 3) Removed hyperlinks from older entries (formatting change). None of these indicate addressing a specific security vulnerability or adding security documentation.
