 - #6243 apache-ranger authorizer as plugin is not supported in DataHub Kubernetes deployment.
 - #6243 Authentication and Authorization plugins configuration are removed from [application.yml](../../metadata-service/factories/src/main/resources/application.yml). Refer documentation [Migration Of Plugins From application.yml](../plugins.md#migration-of-plugins-from-applicationyml) for migrating any existing custom plugins. 
 - `datahub check graph-consistency` command has been removed. It was a beta API that we had considered but decided there are better solutions for this. So removing this.

 - `graphql_url` option of `powerbi-report-server` source deprecated as the options is not used.

 - #6611 - Snowflake `schema_pattern` now accepts pattern for fully qualified schema name in format `<catalog_name>.<schema_name>` by setting config `match_fully_qualified_names : True`. Current default `match_fully_qualified_names: False` is only to maintain backward compatibility. The config option `match_fully_qualified_names` will be deprecated in future and the default behavior will assume `match_fully_qualified_names: True`."
