+### Overview
+
+The Life360 integration has been converted from the old "legacy"
+implementation (which uses `known_devices.yaml`) to the newer entity based
+design, similar to what was done back in the 0.94.0 release to many other
+device tracker integrations.
+
+Due to this change, all your existing Life360 entities will become
+non-functional, and there will be new entities, with different entity IDs,
+that _are_ functional.
+
+### Steps to replace old entities with new ones
+
+1. Edit the `known_devices.yaml` file in your configuration directory to
+remove any Life360-related entries. Or, if there are only Life360 entries in
+this file, simply delete the file entirely.
+2. Restart Home Assistant. All the old, non-functional Life360 entities
+should now be gone.
+3. Go to the Entities page (under Settings -> Devices & Services -> Entities)
+and change the entity IDs for the new Life360 entities as desired.
+
+### Removed/changed functionality
+
 The previously deprecated YAML configuration of the Life360
 integration has been removed.
