 ### Builds after release 0.12.0
 
+#### Build 2106241
+
+-   BREAKING: Added ability for usermods to force a config save if config incomplete. `readFromConfig()` needs to return a `bool` to indicate if the config is complete
+-   Updated usermods implementing `readFromConfig()`
+-   Auto-create segments based on configured busses
+
 #### Build 2106200
 
 -   Added 2 Ethernet boards and split Ethernet configs into separate file
