No changelog entry is added since it does not belong to any of the three categories.

In fact, it still depends on the rand, but from ark_std, and it depends on the same version 0.7.

A bump to the new version 0.8 would be done after individual repos' dependency on rand is removed (otherwise there would be an error).
