Action Checklist
- Evaluate project dependencies for compatibility with the native TypeScript 7.0 compiler Check if custom compiler plugins or AST transformers require updates.
- Install TypeScript 7.0 in a development or staging branch Run initial builds locally before pushing changes to the remote repository.
- Verify type-checking accuracy and compare build times against previous versions Document any performance improvements and resolve new compiler errors.
