Release Notes - **Release date: July 21, 2026** ### Fixes - We fixed an issue where projects located in a folder whose name contained special characters (for example an '&') would fail to run locally. (Ticket 275109) - We fixed an issue in React client mode where navigating between pages with the same layout left widgets unresponsive. (Ticket 276710) - On SQL Server, when a unique constraint or foreign key constraint is dropped, we now use `IF EXISTS`. This avoids an automatic rollback of the synchronization transaction in case the constraint does not exist. (Ticket 279545) - We fixed an issue where runtime fails to finish executing a queued task started by a user if the user is deleted during task execution. (Ticket 279891) - We fixed an issue where the native `Switch` widget did not render correctly on iOS. (Ticket 280839) - We fixed an issue with PWAs using Rspack where the service worker would sometimes not be created correctly. (Ticket 282616, 282601) - We fixed the `t is not a function` crash in workflow and page editors, introduced by the recent Microsoft update for WebView. If you installed an older version of the Microsoft Edge WebView as a workaround and you have no other affected Studio Pro installations, we recommend uninstalling it to prevent future compatibility issues. (Ticket 282685) - We fixed an issue in the call web service activity and in consumed OData services that consume services using OData version 3. The XML parser now rejects DTD declarations and external entities, because a compromised server might exploit those features. - We fixed an issue where pressing Escape to close a modal dialog would also close the sidebar. ### Deprecations - We dropped support for the following database versions that are no longer supported by the vendors: - PostgreSQL 13 - MariaDB 10.6
