 ### Fixed
 
 - Fixed serialization of `MclBilinearGroup` returning "bn256" instead of the correct "bn254" which lead to deserialization not working
 
-
 ### Changed
 - Made most of the mcl wrapper classes package-private

 # Mclwrap
 
 Mclwrap provides a wrapper around the BN-254 bilinear group implemented in the [MCL library](https://github.com/herumi/mcl). As the bilinear groups implemented in the Cryptimeleon Math library are not particulary efficient, use of this wrapper is recommended for proper benchmarks.
