June 2025 focused on UX improvements and data integrity for opf/openproject, delivering a cohesive set of enhancements that increase user productivity, reliability, and extensibility. Key deliverables include a UI-driven Time Tracking Pages overhaul with navigation improvements and empty-state handling, the introduction of GID-based work package links, support for entities from Cost- and TimeEntry contexts, and enhancements to journaling via polymorphic associations. Calendar view was refined to collapse non-current-week days for focused planning.
