 Version 2.02.106 - 
 ====================================
+  Use correct rl_completion_func_t typedef for new readline.
   Make lvm 'dumpconfig --type default' complete for it to be consumed by lvm.
   Run pvscan --cache via systemd-run in udev if the PV label is detected lost.
   Fix memleak when lvmetad discovers PV to appear on another device.
