Release Notes - **Release date: March 8th, 2021** ### Improvements * We upgraded the Swagger UI component for viewing the [Open API specification](https://docs.mendix.com/refguide8/open-api) for [published REST services](https://docs.mendix.com/refguide8/published-rest-services) from 3.31.1 to 3.40. * As part of ongoing maintenance, we reduced the memory footprint and improved the performance of Studio Pro and [MxBuild](https://docs.mendix.com/refguide8/mxbuild). * We added [support](https://docs.mendix.com/refguide8/system-requirements#databases) for PostgreSQL 13. ### Fixes * We fixed an issue in [published OData services](https://docs.mendix.com/refguide8/published-odata-services) where an error occurred when a client queried the service using `$select` in combination with expanding (`$expand`) an association from the child's side. (Ticket 113523) * We fixed an issue in [consumed web services](https://docs.mendix.com/refguide8/consumed-web-services) that logged a message "Operation getFaultNode not supported" when calling a SOAP 1.1 web service even though there was no problem. (Ticket 114070) * We fixed an issue in [published REST service](https://docs.mendix.com/refguide8/published-rest-services) POST operations with file form parameters where an empty file was written to storage when the body did not contain a part for it. Now, no file is written to storage. (Ticket 114991) * We fixed an issue where adding a snippet call without a snippet led to an error. (Ticket 114041) * We fixed an issue where the **View** > **Phone/Tablet** options did not work for apps deployed to Mendix Cloud. (Ticket 114471) * When an average of a list is calculated by the database, the result is no longer truncated. (Tickets 111779, 112782) * We updated access rules for the user’s password attribute to prevent access to its hashed value. * We fixed a bug where an incorrect number of revisions was shown after a successful update. ### Known Issues * When you update a [consumed OData service](https://docs.mendix.com/refguide/consumed-odata-service) with a new version from [Mendix Data Hub](https://docs.mendix.com/data-hub/index) 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 project and opening it again fixes this issue.
