Those two packages are now at: * [https://github.com/narimiran/blake2](https://github.com/narimiran/blake2) * [https://github.com/narimiran/sha3](https://github.com/narimiran/sha3)
Nimble's `packages.json` has been updated with the new locations, so the installing them should be the same as before (but now using `git`, not `hg`), e.g.: `nimble install blake2`.
