 # News
+- change DST of hash-to-curve for `MCL_MAP_TO_MODE_HASH_TO_CURVE_06`.
 - add new hash-to-curve function of [draft-irtf-cfrg-hash-to-curve](https://cfrg.github.io/draft-irtf-cfrg-hash-to-curve/draft-irtf-cfrg-hash-to-curve.txt) at March 2020.
   - call `setETHmode(MCL_MAP_TO_MODE_HASH_TO_CURVE_06);`
   - The older `MAP_TO_MODE` will be removed after the draft is fixed.
