⚠ BREAKING CHANGES

Features

• codetable: remove identity hasher (#289) (8473e2f)
• Serde serialize Multihash in bytes representation (#302) (1023226)

Bug Fixes

• avoid possible panic in error handling code (#277) (5dc1dfa)
• don't panic on non minimal varints (#291) (6ef6040), closes #282
• expose MultihashDigest trait in codetable (#304) (50b43cd)

Code Refactoring

• split crates into multiple to isolate breaking changes (#272) (954e523)

Migrating

When upgrading to v0.19, consider the following:

• Code has moved from multihash::Code to multihash_codetable::Code. It's strongly recommended to define your own code table using multihash_derive. Check the custom codetable example on how to use it. For the simplest migration, use the multihash_codetable::Code.

  Before

  use multihash::{Code, MultihashDigest};
  fn main() {
  let hash = Code::Sha2_256.digest(b"hello, world!");
  println!("{:?}", hash);
  }

Looks like multihash is up-to-date now, so this is no longer needed.
