+### Improvements
+
+* We improved **Change Data Capture** event publishing performance by sending events in batches and updating the Kafka Producer configuration.
+* We added a reminder to change the version number when exporting a module, because the version number is automatically used by Mendix Marketplace.
+* We improved the App Bundle error dialog to show clearer error messages and the location of the full app bundle log.
+
+### Fixes
+
+* We fixed an issue where files larger than 5 MB could not be downloaded when encryption is enabled for S3. (Ticket 279197)
+* We fixed an issue where clearing the selection with a JavaScript action did not work for data widgets with **Keep selection** enabled, such as the Data Grid 2 widget. The previously selected rows became selected again. (Ticket 280575)
+* We fixed an issue where an optional microflow, nanoflow, or page parameter that was explicitly configured as **(none)** still received a default value at runtime instead of being left empty. (Ticket 284412)
+* We fixed an issue where retrieving objects in offline apps failed with a SQLite **No such column** error when an XPath constraint traversed an association to a referenced entity with specializations. (Ticket 286965)
+* We fixed an issue with the **Call REST Service** activity where the response handling was set to **Apply import mapping** with a parameter, but the provided parameter had a type that did not match what the **Import Mapping** expected. This led to an error message. Now it correctly shows consistency error CE0245. (Ticket 287936)
+* We fixed an issue where the diff of values was not shown correctly during a merge conflict.
+* We fixed a crash that occurred when selecting a branch in the App Selector in Studio Pro. This crash occurred when information about the Mendix version was missing from a branch.
+* We fixed an issue where documents created by the user incorrectly appeared in the Maia changes list.
+* We fixed an issue where users who were not signed in to Mendix Platform could not configure and use a custom LLM provider to chat with Maia.
+* We fixed an issue where the Java sources of protected modules were added to the Eclipse build path.
+* We fixed an export issue of app-level Maia Agent Skills (*SKILLS.md*) and Agent Instructions (*AGENTS.md*) in solution packages (*.mxsolution*) and regular app packages (*.mpk*).
+* We fixed an issue where the Modernized App Explorer was in a state where the visible nodes and the cursor position were shifted after it scrolled automatically to a position.
+
+### Known Issues
+
+* The Maia Chat pane may appear and remain functional even when Maia is disabled in **Edit** > **Preferences**.
+  * Workaround: Manually close the panel when it appears.
+* When using BYO LLM, switching back to the Mendix Platform provider and saving your configuration causes reasoning and caching to stop functioning.
+  * Workaround: Click **New Chat** to restore reasoning and caching. Note that **New Chat** is only available when the chat is not empty.
+* When you use the new module update flow (when you right-click a module and choose **Update from file..**), the StorageGuids and StableGuids for native mobile are not restored. This will lead to data loss when the app is started. The usual import module flow (**App** > **Import module or Download from Marketplace**) is not affected by this issue.
