related to #81

parity-scale-codec has released new version 2.0.0, and now it's 2.1.1. It has more features for this crate, and some part is not compatible with 1.3.5 version. In our project, we need this new version parity-scale-codec, please update it.

Thanks.

We can help to review this. But need you guys to merge this pr and release new version to crates.io

@atenjin Good to hear that you use that feature. There is currently a PR open to remove parity-scale-codec support from rust-multihash, seems like we shouldn't remove it.

The parity-scale-codec was a breaking change in 2.0.0. It would be great if you could provide a PR to rust-multihash that upgrades to 2.0.0.

Once the new version of rust-multihash to be released, I will open a PR to bump the parity-scale-codec to v2.
