Release Notes - **Release date: April 15th, 2021** ### Fixes * We fixed an issue in the [Call REST service](https://docs.mendix.com/refguide8/call-rest-action) activity with form-data content. The **Content-Type** request header now no longer contains additional whitespace. (Ticket 118389) * We improved the domain model editor performance so that it renders the domain model more quickly when there is a large number of entities (for example, more than 50). (Ticket 118284) * We fixed an issue with key-not-found when exporting a JSON/XML in an [export mapping](https://docs.mendix.com/refguide8/export-mappings) document. (Ticket 117965) * We fixed an issue that occurred when editing a message definition after deleting an association from the domain model. ### Known Issues * When you update a [consumed OData service](https://docs.mendix.com/refguide8/consumed-odata-service) with a new version from [Mendix Data Hub](https://docs.mendix.com/data-hub/) but close the document without saving, the blue arrow icon will no longer be shown to notify you about the available update for that service. * Workaround: Closing your app and opening it again fixes this issue.
