+## RECENT NEWS
+The modernization of repository artifacts, issues, and documentation is underway: 
+* Initial cleanup is expected to be completed by **June 30, 2026**.
+* The first wave of major structural changes (3.0) is expected to be released by **December 31, 2026** and will incorporate GeoSPARQL, QUDT, and the refactoring of information.
+* The second wave of major structural changes (4.0) is expected to be released **June 30, 2027**.
+
+It is the recommendation of the CCO Governance Board that users wait to update following 4.0 release. In the meantime, users who would like to use versions of CCO with the up-to-date changes, are directed to pull from the 'develop' branch. For a high-level overview of planned updates, see the milestones displayed below. See here for an accompanying [slide deck](https://github.com/CommonCoreOntology/CommonCoreOntologies/blob/develop/documentation/user-guides/Beverley%20-%20P%26G%20CCO%20Modernization%20Brief.pptx).

-***IMPORTANT NOTE***  
-Starting with version 2.0, CCO IRIs are using a new namespace and have opaque local identifiers for all ontology elements.  
-See [here](https://github.com/CommonCoreOntology/CommonCoreOntologies/tree/develop/documentation/mapping-new-iris) for the mapping file.
