Deprecated Features
Deprecated features do not require any action before upgrading to Talend Data Catalog 8.1. If any of these features are used in worksheets, dashboards, conditional labels and collections created in the previous release, they will be automatically upgraded. In order to use any of these features in MQL queries in the REST API functions, you need to set the mqlVersion parameter to 1 or 2 so that they can be automatically upgraded. If you use any deprecated feature in the filters entered manually, you may get a warning about the field cannot be resolved to a valid attribute, in which case, you will need to replace the deprecated feature with the new feature by yourself.
