AWS transform documentation change

Service: transform · 2026-04-04 · Documentation low

File: transform/latest/userguide/transform-aws-customs.md

Summary

Added new AWS-managed transformations including Java performance optimization, Vue.js version upgrade, Angular version upgrade, and Log4j to SLF4J migration

Security assessment

The change adds documentation for new transformation services, including a Log4j to SLF4J migration transformation. While Log4j has known security vulnerabilities, this documentation describes a migration service feature rather than addressing a specific security incident or vulnerability. The description focuses on migration functionality without mentioning security remediation.

+  * `AWS/early-access-log4j-to-slf4j-migration` \- [Early Access] This transformation migrates Java applications from Log4j (1.x/2.x) to SLF4J with Logback backend. Handles source code, dependency management (Maven/Gradle), and logging configuration files. Validates via compile, test, and residual import scan.
