 Version 2.02.92 - 
 ====================================
+  Skip pv/vg_set_fid processing if the fid is same.
   Check for foreach loop errors in _vg_read_orphans() (2.02.91).
   Clean error paths for format instance creation (2.02.91).
   Release vg in error path of _format1_vg_read() instead of just free().
