+### Improvements
+
+- Entity set to online synchronization mode can now be used by non-pluggable widgets on offline pages.
+- We added a configurable option **Use new string behavior** in the **Runtime** tab that controls how null and undefined values are handled for string attributes in the client. The new behavior (default for new projects) keeps these values as null to maintain consistency between nanoflows and microflows, while the old behavior converts them to empty strings. This option provides backward compatibility and gives developers time to migrate to the new more consistent behavior.
+- We have improved the performance of session cleanup.
+
+### Fixes
+
+- We fixed an issue where a remote entities with Decimal primary keys would cause errors on startup on existing deployments.
+- We fixed an issue with modern client offline apps that caused data sources of the home page to be executed too early causing errors because the offline system was not fully initialized.
+- We fixed an issue where a widget configured with an incorrect type of primitive parameter did not show a consistency error and could result in an error in the client.
+- We fixed an issue with the [tab container](https://docs.mendix.com/refguide11/tab-container/) widget. It would reset to the first tab when returning to the page, causing data sources to reload unnecessarily and other tabs to be blocked. (Tickets 266083, 266090, 267249) 
+- We fixed an issue where the "Find Advanced" -> "Unused Items" feature would list enumerations as unused, even when they were actually used (in Microflow expressions). Now, enumerations whose values are used in your project are no longer falsely reported as unused. (ZenDesk: #253576)
+- We fixed an issue when the last attributes were cut-off in entity properties dialog. (Tickets 266554, 260953, 256106, #51278, 255882)
+- We fixed an issue on macOS when while typing in the search field the text would get highlighted automatically and overwritten by subsequent characters. (Ticket 267303)
+- We fixed the issue where typing in a Dataset document was slow, causing delays in displaying each character. (Ticket 263330)
+- In the logic editors, we fixed an issue when extracted microflow did not have all parameters for newly created activity. (Ticket 265542).
+- Fixed an issue where Maia explain for Microflows crashes sometimes.
+- We fixed an issue in Maia chat causing it to crash when a Studio Pro version attribute was missing in a reference.
+- We fixed scenarios in Android where navigating fields of a data view, of different types, would not be possible using an external keyboard.
+- We fixed an issue that caused setting the image of a building block to show an error dialog instead of resizing the image. (Ticket 268856)
+- We fixed an issue where an interruption while fetching data, would lead to model changes not being displayed properly in the new history pane.
+- Fixed an issue during local development where system texts would not be updated in the application when hot-reloading. They are now correctly updated without the need to fully restart the server.
+- We fixed an issue where an Oops pop-up window appeared when page actions with return value mappings were copied and pasted or extracted to a snippet.
