+-----------------------------------------------------------
+WHAT WAS *NOT* DONE, and you need to do now:
+ 1) You need to choose if the new HAL is optional or not for new devices.
+    Either add or replace $BASE_VERSION by $NEW_VERSION in
+    compatibility_matrices/compatibility_matrix.current.xml
+    Do not forget to update both the "audio" and "audio.effects" HAL'
+
+ 2) Then you need to choose a device to update its audio HAL implementation:
+    a) Update the HAL manifest of your device: open your device manifest.xml
+       and replace $BASE_VERSION by $NEW_VERSION for both
+        - android.hardware.audio
+        - android.hardware.audio.effect
+    b) Go to your device device.mk (usually next to the manifest) and replace:
+        - android.hardware.audio@$BASE_VERSION-impl by
+          android.hardware.audio@$NEW_VERSION-impl
+        - android.hardware.audio.effect@$BASE_VERSION-impl by
+          android.hardware.audio.effect@$NEW_VERSION-impl
