 Version 2.02.99 - 
 ===================================
+  Fix autoactivation to not autoactivate VG/LV on each change of the PVs used.
   Skip mlocking [vectors] on arm architecture.
   Exit pvscan --cache immediately if cluster locking used or lvmetad not used.
   Don't use lvmetad in lvm2-monitor.service ExecStop to avoid a systemd issue.
