 Version 2.02.100 -
 ================================
+  Add --with-thin-repair and --with-thin-dump configure options.
+  Add lvm.conf thin_repair/dump_executable and thin_repair_options.
   Require 1.9 thin pool target version for online thin pool metadata resize.
   Ignore previous LV seg with alloc contiguous & cling when num stripes varies.
   Fix segfault if devices/global_filter is not specified correctly.
