 Version 2.02.76
 ===================================
+  Fix NULL pointer dereference for too large MDA error path in _vg_read_raw_area().
   Use static for internal _align_chunk() and _new_chunk() from pool-fast.c.
   Fix vgchange to process -a, --refresh, --monitor and --poll like lvchange.
   Add lvm2app functions to query any pv, vg, or lv property / report field.
