 - Version 4.8.0 is the first release of BlazeDS from Apache that includes a
   binary distribution
 - BlazeDS now requires Java 8 or newer
-- Removed the flex-messaging-proxy module
-   - If your services-config.xml or proxy-config.xml file defines a service using the flex.messaging.services.HTTPProxyService class, this service will need to be disabled.
-- Removed the blazeds-spring-boot-starter module
+- Disabled the flex-messaging-proxy module because it required a third-party
+  dependency that is no longer maintained
+   - If flex.messaging.services.HTTPProxyService is referenced in
+     services-config.xml or proxy-config.xml, BlazeDS now logs an error
+     that this type of service is no longer supported
+- Removed the blazeds-spring-boot-starter and blazeds-spring-boot-archetype
+  modules because they required a third-party dependency that is no longer
+  maintained
