CKM 1.21.0 represents one of the most significant upgrades to the Clinical Knowledge Manager platform to date, delivering a large set of enhancements focused on performance, governance, usability and interoperability. This release addresses over 190 improvements across functionality, stability, and user experience, supporting the evolving needs of the global openEHR community. 

While some upgrades are highly visible, many others strengthen the foundations of CKM to deliver faster performance, clearer governance, and more reliable integrations.

Key Improvements in CKM 1.21.0

1. Smarter, Faster Search
Search in the “Find Resources” area is now significantly more intelligent and performant. Exact phrase searching using quotation marks is supported, and special characters such as slashes and brackets no longer break search logic. Result relevance has been improved, with better visual indicators showing where matches were found inside resources. 

2. REST API Enhancements
The REST API now supports retrieval via semantic versions, along with direct access to the latest published resources. New API endpoints allow teams to query Change Requests and Resource Proposals using robust filtering. ISO date formats with fractional seconds are now supported, improving compatibility with third-party systems.

3. Improved User and Membership Management
Project membership and role management panels have been redesigned to provide a clearer, more modern experience. Administrators can now suspend users for security purposes, improvements have been made to auditing of user lifecycle events, and large user lists now perform better through paging and better filtering. 

4. Stronger Archetype and Template Governance
CKM now supports direct, stable links to specific semantic versions of resources and provides clearer control when working with resources under reassessment. Revision history filtering has been enhanced, a new release-notes view is available for resources, and Markdown formatting is now supported in key descriptive fields. Validation during template upload has also been strengthened. 

5. Expanded Mappings and Interoperability Support
Support for FHIR, OMOP and AQL mappings has been significantly expanded. New reporting tools allow better visibility of mappings across projects. Bulk upload of mapping files is now supported, as well as improved handling of semantic versioning across mapping artefacts. Mappings can now be included in Release Sets. 

6. Editorial Workflow Improvements
Change Requests and Editorial Tasks dashboards have been rebuilt to support advanced filtering, grouping, and export options. Review rounds have been enhanced, allowing easier reviewer management, clearer communication, and safer handling of active review cycles. 

7. SEO, Sharing and Visibility Enhancements
CKM now generates more robust previews for social platforms such as LinkedIn, BlueSky, Discourse, Teams and Slack using improved OpenGraph metadata. Direct links to archetypes and templates are more stable and shareable. 

8. ADL 2.4 Export Support
As part of forward compatibility work with openEHR specifications, CKM can now export ADL2 archetypes using AT-coded identifiers, aligned with emerging ADL 2.4 standards. This improves stability for downstream systems relying on consistent identifiers. 

9. Performance and Scalability Gains
Search and query performance has improved significantly – with some searches running up to 50× faster. Large audit logs are now capped for responsiveness, caching has been improved for common downloads, and paging has been introduced in key admin panels. 

What’s Next?
CKM 1.21.0 lays the foundation for future clinical modelling capabilities, stronger interoperability and improved collaboration workflows. Work will continue to build on these technical and usability improvements in upcoming releases.

As always, the openEHR community’s feedback continues to guide our roadmap.
