- Introduced a new read-only file system for seed data, enhancing initial data seeding capabilities. - Updated the file system registration to include the seed root and clarified comments regarding the use of app, data, system, DSL, and script registrations, marking them for future deprecation. - Improved code clarity and maintainability by restructuring file system registrations.
