12 Commits • 4 Features
Jun 1, 2026June 2026 delivered performance enhancements, privacy improvements, and foundational infrastructure work in the Sakai project. Notable outcomes include on-demand loading of site data to reduce upfront UI load, privacy-aware CC export logic to strip user messages, restoration of the Gradebook double-click edit interaction, and stabilization of tests with unique Elasticsearch event names. Internally, we completed a major migration to JPA for hierarchy management, modernized permission handling, transactional initialization for permission levels, demo properties loading, dependency upgrades (including Ignite 2.18.0), and release notes/acknowledgments updates for the 25.2 release. These changes improve user performance, data privacy compliance, test reliability, and provide a scalable foundation for future features.
