Code Review

This pull request prepares the project for the next development phase by updating the version to 21.4.0-SNAPSHOT across all modules and updating several dependencies. The changes are consistent and appear correct. My review includes several suggestions to improve maintainability by removing hardcoded version strings in documentation and shell scripts. Applying these suggestions would make future version bumps easier and less error-prone.
