 Version 1.02.75 - 
 ================================
+  Remove dmeventd fifos on exit if they are not managed by systemd.
   Use SD_ACTIVATION env. var. in systemd units to better detect systemd in use.
   Do not run a new dmeventd instance on restart if there's no existing one.
   Make the time window for reading fifo longer 5sec (1.02.73).
