Oct 1, 2025October 2025 — Sakai (sakaiproject/sakai): Delivered two targeted core fixes that improve data integrity and content accessibility in key workflows. Gradebook category lookup fix prevents incorrect gradebook group data by using the correct site ID when retrieving category definitions; Lesson Builder hidden folders semantics fix clarifies hidden content access by renaming the folder and applying the appropriate content flag. These changes reduce risk of data misalignment and improve user experience in grading and content access.

Jul 1, 2025July 2025 (2025-07) delivered targeted features and critical fixes across the Sakai repository to improve usability, governance, and reliability. Key features modernized UI icons in Discussions/Messages, exposed a default for single-instance content hosting, and tightened UI behavior for push notifications. Major fixes addressed folder creation errors, gradebook item retrieval under grouped contexts, grouped CSS styling, and lessons sub-page navigation. Additionally, access to export statistics was restricted to users with grading permissions, and TA-focused views were constrained to TA associations to improve data integrity and relevance. Collectively, these changes reduce user friction, enhance security and governance, and set the stage for scalable content hosting and reporting.
