+### Improvements
+
+- We improved the rendering performance of repeating widgets in Design mode, by only rendering a single repeat for widgets within a snippet call, parent layout, or nested within another repeating widget.
+
+### Fixes
+
+- We fixed an issue in the React client where autofocus was incorrectly triggered by dynamically loaded widgets, causing combo boxes that use a widget with a dynamic source in their custom content to unexpectedly lose focus and close. (Ticket 254768)
+- We fixed an issue where **Import Mappings** using 'Find an object (by key)' or 'Call a microflow' did not create an object for valid input. (Tickets 255130, 260462)
+- We fixed an issue where Node.js would run out of memory during the bundling process of very large, complex applications using the React client. (Ticket 257472)
+- In the logic editors, we fixed the zoom in and zoom out behaviors of error-handling icons. (Ticket 258424)
+- We improved the performance of the tree control that allows you to select elements for **Message Definitions**, **Import Mappings**, **Export Mappings** (Ticket 258606).
+- We fixed an issue where a Java action could still cause compilation errors, even if excluded from the project. (Ticket 259414)
+- We fixed an issue when there were no conflciting changes users were not properly informed and metadata was missing due to cherry pick.
+- We fixed a few memory leaks in React client, most notably when closing and open pages.
+- We fixed a memory leak when re-opening a project, or switching branches in Studio Pro.
+- We fixed an issue for **Export Mappings** where a recursive XSD structure was not properly marked as invalid in case more than 1000 mandatory elements were auto-selected.
+- We fixed an issue in Studio Pro where restarting Windows with an open app and then opening the app again would result in a warning dialog window about the app already being open.
+- We fixed an issue where task queue tasks were not able to mark themselves as completed after execution.
