 # Release 2.7 (March 2021)
 
-Release 2.7 adds support for:
-* No new features
+Release 2.7 adds:
+* Performance improvements in the graph repo
+* Changes to metadata types
+* Changes to the distribution process
 
 Details of these and other changes are in the sections that follow.
 
 ## Description of Changes
 
 ### Build & Release changes
 
-* Previously egeria maven artifacts have been pushed to JCenter as well as Maven Central. As of 2.7 this no longer occurs due to the site's deprecation.
-* Due to the above, maven artifacts may be signed by a different user to previously (and this may change in a future release). This is only a concern if you verify the GPG key
+* Previously release maven artifacts have been pushed to JCenter (in addition to Maven Central), and snapshots have been pushed to odpi.jfrog.io/odpi/egeria-snapshot. As of 2.7 this no longer occurs and release and snapshots are pushed only to Maven Central.
+* Due to the above, maven artifacts may be signed by a different user to previously (and this may change in a future release). 
+
+### Performance Improvements
+
+* Release 2.7 includes performance improvements to the graph repository's search methods, which select an efficient query strategy based on the properties and type filters supplied to the search.
+
+### Metadata Types
+
+* We have removed overloaded properties that existed at multiple levels in a type definition: for example, length was defined both on SchemaAttribute and again on RelationalColumn (which is a subtype of SchemaAttribute). This change removes them from being defined again the lower level (RelationalColumn in this example); however, the property itself will still be available at the lower level due to inheriting it from the supertype.
 
 ### Bug fixes and other updates
-* Bug Fixes
+* Additional Bug Fixes
 * Dependency Updates
 
+For details on both see the commit history in GitHub.
+
+## Known Issues
+
+* It is recommended to use a chromium-based browser such as Google Chrome or Microsoft Edge, or Apple Safari for the Egeria React UI. Some parts of the UI experience such as Dino currently experience problems with Firefox. See [odpi/egeria-react-ui#96](https://github.com/odpi/egeria-react-ui/issues/96) .
+* When running the 'Understanding Platform Services' lab, ensure you run the 'egeria-service-config' notebook first and do not restart the python kernel before running this lab. See [#4842](https://github.com/odpi/egeria/issues/4842) .
