For March 2025, delivered two core backend improvements in pimcore/studio-backend-bundle that enhance data integrity and runtime reliability. The Translation Schema Initialization Bug Fix corrects the keys array initialization to use PublicTranslations::PUBLIC_KEYS as a single array, eliminating a double-array structure and preventing potential runtime data errors. The User Information Schema Validation Enhancement makes 'classes' and 'docTypes' required fields, improving data integrity and reducing processing errors due to missing user-related data. These changes reduce downstream issues in translations and user data processing, supporting more reliable features and analytics across services. Implemented with commits 7106461cdd9cc553fcc7378f1de1d01a570defb0 and cd5d30072cc3c5a8f5d89456adbb49dbe6408a23, trackable via issue references (#907, #916).
