AWS cli documentation change

Service: cli · 2026-02-10 · Documentation low

File: cli/latest/reference/ec2/describe-launch-template-versions.md

Summary

Updated CLI version reference and added documentation for secondary network interfaces in launch templates including fields like DeleteOnTermination, PrivateIpAddresses, and InterfaceType.

Security assessment

The changes document new networking features (secondary interfaces) but don't address any security vulnerabilities or weaknesses. The DeleteOnTermination field describes resource cleanup behavior, not a security control.
