Feb 1, 2026

February 2026 monthly summary for owncloud/reva and owncloud/ocis. Delivered targeted security, reliability, and tooling improvements that enhance authentication, public sharing workflows, and developer productivity. Key outcomes include: streamlined authentication and permissions for user shares; enabling archive downloads from password-protected public links; hardened error handling in the UserShareProvider; Go 1.25 runtime and CI/tooling refresh; and enabling public link archive downloads via signature-auth in OCIS. These changes reduce risk of internal error exposure, improve user experience for public shares, and strengthen performance and security posture across the stack.

November 2025 performance: Implemented OCM Sharing Compliance Enhancement in owncloud/reva, delivering a robust alignment with the OCM specification. Key changes include removing base64 encoding for user IDs, ensuring federated user permissions are correctly managed, and addressing issues related to user identification. This work improves reliability and interoperability of cross-provider sharing and simplifies permission handling, laying groundwork for future OCM-driven features. Validation included updates to OCM-related tests and fixes to edge cases (e.g., undefined ocmuser.RemoteID) and related components (gowebdav, provider permission handling).

Oct 1, 2025

For 2025-10, focused on reliability and API consistency in owncloud/reva. Implemented two critical bug fixes that improve data integrity and WebDAV API stability: - Storage Cache Invalidation on Storage Space Deletion: fixed cache invalidation to prevent stale data being served after a storage space is deleted (commit 70000d32239f003c3593634212e676ad60b5b40f). - OCM WebDAV URI Field Standardization and Backward Compatibility: renamed URL field to URI in WebDAV structures and methods, with backward compatibility for the url field during JSON unmarshalling to ensure consistent WebDAV endpoint references (commit bcc65ff3b7f152d9eaff215059a614897b16ee39).
