During September 2025, the team delivered major releases and enhancements across Invenio RDM components, focusing on robust deletion workflows, accurate user notifications, and maintained compatibility with key dependencies. Key features included the Invenio-RDM Records 21.0.0 release with deletion workflow improvements and updated validation, improved guest access request notifications, and dependency compatibility maintenance for invenio-checks and invenio-communities. In Invenio App RDM, the deletion policy and deposit UI enhancement introduced an admin 'Requests view' for record deletion and policy configurability, with UI logic corrected to use API record evaluation. A parallel maintenance effort updated core dependencies and performed release housekeeping and code cleanup. Major bugs fixed include aligning Marshmallow schemas with request actions for deletion, ensuring deposit UI evaluation uses the API record, and improving guest notification tests. Overall, these changes reduce deletion-related risks, improve user communications and governance, and keep the platform aligned with upstream libraries, enabling smoother upgrades and faster delivery of value to researchers and admins.
