 Version 2.02.85 - 
 ===================================
+  Use format instance mempool where possible and adequate.
   Call destroy_instance for any PVs found in VG structure during vg_free call.
   Add new free_pv_fid fn and use it throughout to free all attached fids.
   Use only vg_set_fid and new pv_set_fid fn to assign the format instance.
