-### Roadmap
+### Product Improvements Related to Local Network Access
+
+Dynamic Web TWAIN v19.3 introduces **user-experience enhancements** to better surface local service connectivity and permission issues.
 
-Dynamsoft plans to add a feature that automatically detects local service connectivity and permission status. If the connection is blocked, users will be prompted with a message and directed to this FAQ page.
+These changes **do not alter or bypass Chromium’s security model**. Their purpose is to make permission-related failures easier to identify and understand, and to guide users to the appropriate browser settings when access is blocked.
 
-Here are the details:
+The key improvements include:
 
-* When local network access is blocked, prompt the user with the following dialog:
+* **Explicit detection of blocked local network access** \
+When the browser blocks communication with the local service, a clear dialog is displayed explaining the cause and directing users to this FAQ.

-* Add a sentence about the permission in the service installation dialog, since we cannot determine whether the connection failure is due to the service not being installed or the access being blocked.
+* **Clearer messaging during service installation** \
+A notice is added to the service installation dialog to inform users that a connection failure may be caused either by the service not being installed or by local network access being denied, as these two cases cannot be reliably distinguished.

+These improvements are **available starting with Dynamic Web TWAIN v19.3**.
 
-This design will be integrated in v19.3. For old versions, we can include an extra js file, which can be retrieved by contacting [support](mailto://[email protected]).
