+# Threshold value is ignored (all shares are n=3)
+
+Affected versions of this crate did not properly calculate secret shares requirements.
+
+This reduces the security of the algorithm by restricting the crate to always
+using a threshold value of three, rather than a configurable limit.
+
+The flaw was corrected by correctly configuring the threshold.
