 # Changelog
 
+## 3.0.6
+
+- Correct async PlatformIO dependency owners to the registry's canonical lowercase identity, so a clean consumer builds WiFiManager and its ESP8266/ESP32 transport dependencies without duplicating them in `lib_deps`. Remove the superseded include-path bridge.
+
 ## 3.0.5
 
 - Add a library-owned PlatformIO bridge for the asynchronous web/TCP include paths required when WiFiManager is nested beneath DeviceFramework.

 ## Installation
 
-Use the release tag and list the asynchronous web/TCP packages at project level.
-PlatformIO installs the manifest dependencies automatically, but its dependency
-finder requires these headers to be direct project dependencies before it adds
-their include paths:
+Use the release tag. The package manifest resolves DFTE, the asynchronous web
+server, and the platform-specific TCP library automatically:
