# CHANGELOG
Entries are listed in reverse chronological order.
# 2.1.0
* Add `PartialOrd`, `Ord`, `Hash` implementations for `VerificationKey`,
forwarding to the implementations on `VerificationKeyBytes`.
# 2.0.1
* Improve `Debug` output for `VerificationKey`.
# 2.0.0
* Remove `Copy` implementation from `SigningKey`.
# 1.2.0
* Add `to_bytes`/`as_bytes` for `VerificationKey`.
* Add `SigningKey::verification_key()` convenience method (instead of `From`).
# 1.1.0
* Support `no_std`.
* Add `to_bytes`/`as_bytes` methods to complement the `Into` implementations (by @0xdeadbeef).
# 1.0.0
* Remove Zcash-specific language, update dependencies, and re-release as
`ed25519-consensus`.
# `ed25519-zebra` changelog entries
## 2.2.0
* Add `PartialOrd`, `Ord` implementations for `VerificationKeyBytes`. While
the derived ordering is not cryptographically meaningful, deriving these
traits is useful because it allows, e.g., using `VerificationKeyBytes` as the
key to a `BTreeMap` (contributed by @cloudhead).
## 2.1.2
* Updates `sha2` version to `0.9` and `curve25519-dalek` version to `3`.
## 2.1.1
* Add a missing multiplication by the cofactor in batch verification and test
that individual and batch verification agree. This corrects an omission that
should have been included in `2.0.0`.
## 2.1.0
* Implements `Clone + Debug` for `batch::Item` and provides
`batch::Item::verify_single` to perform fallback verification in case
of batch failure.
## 2.0.0
* Implements ZIP 215, so that batched and individual verification
agree on whether signatures are valid.
## 1.0.0
* Adds `impl TryFrom<&[u8]>` for all types.
## 1.0.0-pre.0
* Add a note about versioning to handle ZIP 215.
## 0.4.1
* Change `docs.rs` configuration in `Cargo.toml` to not refer to the removed
`batch` feature so that the docs render correctly on `docs.rs`.
## 0.4.0
* The sync batch verification api is changed to remove a dependence on the
message lifetime that made it difficult to use in async contexts.
## 0.3.0
* Change terminology from secret and public keys to signing and verification
keys.
* Remove async batch verification in favor of a sync api; the async approach is
to be developed in another crate.
## 0.2.3
* The previous implementation exactly matched the behavior of `libsodium`
`1.0.15` with the `ED25519_COMPAT` configuration, but this configuration
wasn't used by `zcashd`. This commit changes the validation rules to exactly
match without `ED25519_COMPAT`, and highlights the remaining inconsistencies
with the Zcash specification that were not addressed in the previous spec
fix.
## 0.2.2
* Adds `impl AsRef<[u8]> for PublicKey`.
* Adds `impl AsRef<[u8]> for SecretKey`.
## 0.2.1
* Adds `impl AsRef<[u8]> for PublicKeyBytes`.
## 0.2.0
* Adds experimental futures-based batch verification API, gated by the `batch` feature.
## 0.1.0
Initial release, attempting to match the actual `zcashd` behavior.
