 ## Latest Updates
 
+* 05-24-22:  add `wz_mini.conf` to replace `run_mmc.sh`, all configuration variables are now stored in this file, scripting logic now in wz_user.sh inside init.d folder. add support for user to add a custom script to run on boot.
 * 05-23-22:  added simple wireguard startup configuration.
 * 05-22-22:  added fps variable for rtsp server, thanks @claudobahn.
 * 05-22-22:  Update wz_mini scripts and libraries to support v2 camera.  experimental.
