Release Notes - **Release date: November 4, 2025** ### Fixes * We fixed an issue where incompatible React client widgets did not display an error when they were nested inside a pluggable widget. (Ticket 253896) * We fixed an issue where JSON Import mappings stopped finding objects. (Ticket 258507) * We fixed an issue where a wait-for-timer activity could get stuck when its workflow was upgraded while the activity was active. (Ticket 263288) * We fixed a migration issue when going from 10.24 to 11.x that attempted to recreate an already existing column in a table in an offline app database. * We fixed a bug where the JavaScript Action code editor would overlap with the errors pane after resizing it. * We improved Studio Pro memory usage in operations that involve processing the project's structure (for example find usages and errors check). * We fixed the following bugs in the version selector: * When opening a widget .mpk the file was kept on hold even after closing the dialog, preventing it to be renamed or opened. * Closing the "Version not found" dialog launched the selected Studio Pro version instead of just closing the dialog. * The Studio Pro versions were not displayed with the correct format. * We reduced the size of the Studio Pro installer on Windows. ### Deprecations * We dropped support for the following database versions that are no longer supported by the vendors: * MariaDB 10.5 * Microsoft SQL Server 2019 * MySQL 8.0
