## Proposed Changes Split out several crates which now exist in separate repos under `sigp`. - [`ssz` and `ssz_derive`](https://github.com/sigp/ethereum_ssz) - [`tree_hash` and `tree_hash_derive`](https://github.com/sigp/tree_hash) - [`ethereum_hashing`](https://github.com/sigp/ethereum_hashing) - [`ethereum_serde_utils`](https://github.com/sigp/ethereum_serde_utils) - [`ssz_types`](https://github.com/sigp/ssz_types) For the published crates see: https://crates.io/teams/github:sigp:crates-io?sort=recent-updates. ## Additional Info - [x] Need to work out how to handle versioning. I was hoping to do 1.0 versions of several crates, but if they depend on `ethereum-types 0.x` that is not going to work. EDIT: decided to go with 0.5.x versions. - [x] Need to port several changes from `tree-states`, `capella`, `eip4844` branches to the external repos.
