In March 2026, the xwiki-platform team delivered targeted features and reliability improvements that reduce risk, streamline localization, and strengthen data protection, while enhancing test quality and maintainability. Key features and fixes include: - Localization Streamlining: Removed English (United Kingdom) translation to shrink localization scope, enabling faster updates to core languages and reducing maintenance overhead. - Security hardening in REST API: Removed unfinished cryptographic APIs and introduced a generic obfuscation API for sensitive values (emails and passwords), improving data protection and reducing surface area. - Accessibility enhancement: Added an empty <dd> tag in diff outputs to comply with WCAG rules when obfuscated fields are present, ensuring assistive technologies render diffs correctly. - Authentication test reliability: Hardened test utilities to reset HttpClient credentials when switching user roles and ensured proper admin user setup, yielding more repeatable CI runs. - Core code quality and testing framework enhancements: A broad set of refactors and improvements (checkstyle fixes, revapi cleanup, improved filter stream API, enhanced test utilities, docker-aware testing) that reduce regressions and improve maintainability. Overall impact: Reduced security risk, more stable builds and faster release cycles, clearer localization scope, and a stronger, more maintainable codebase with better accessibility compliance. Technologies/skills demonstrated: REST security design, obfuscation APIs, testing architecture and utilities, checkstyle and static analysis practices, Revapi compatibility, Docker-based test environments, and robust refactoring approaches.
