This is a massive upgrade across multiple major versions, from an initial unstable release (0.x) to a mature version (2.x). This should be treated as a framework migration, not a simple dependency update, and will require significant code and configuration changes.

Highlights:

• Configuration Overhaul: Configuration has been split from a single file into multiple, module-specific YAML files (e.g., security.yml). Your application's configuration loading will need to be completely refactored.
• API & Module Refactoring: Core modules like security, audit, and info have undergone significant API changes and have been broken into smaller, more focused modules. For example, security handlers were refactored, and the audit log's data structure has changed.

Recommendation: This upgrade cannot be merged without a dedicated migration effort. Developers must follow the modern light-4j documentation to adapt the application to the new architecture and configuration model.
