Release Notes - **Release date: September 22, 2025** ### Improvements * We updated the bundled Node.js from v20 to v22. ### Fixes * We fixed an issue where navigating to a screen already in the navigation history caused an unexpected behavior when using the **Side Bar** layout. (Ticket 232247) * We fixed an issue where enumeration values with the name *Core* caused compilation errors. (Ticket 250532) * We fixed an issue where an attempt to retrieve more than 500 external objects by ID at once failed. For example, when retrieving many external objects by association. (Ticket 251911) * We fixed an issue in the interactive documentation (Swagger UI) page for published OData services which indicated it did not support OpenAPI version 3.0.4. (Tickets 256982 and 257611) * We added proper refresh functionality for Marketplace for when a session times out. The reload button will properly handle the event, by closing the details page and refreshing the **Search** tab view. * We fixed the accessibility of the popup modal so now the keyboard is allowed keyboard to reach the **Close** button.
