# CHANGELOG
Entries are listed in reverse chronological order.
# 4.0.3
* Update `curve25519-dalek` to `4.1.0`
# 4.0.2
* Update `curve25519-dalek` to `4.0.0`
# 4.0.1
* Fix no-std build with serde activated (#87)
* Update `curve25519-dalek` to `4.0.0-rc.3`
# 4.0.0
* `Signature` is now an alias for `ed25519::Signature`
* `impl From<Signature> for [u8; 64]` no longer exists; use `to_bytes()` instead.
* `signature::{Signer, Verifier} is now implemented for `SigningKey` and `VerificationKey`.
* Updates `sha2` version to `0.10` and `curve25519-dalek` version to `4.0.0-rc.2`.
* Add DER & PEM support for SigningKeySeed and VerificationKeyBytes (RFC 8410) #46 https://github.com/ZcashFoundation/ed25519-zebra/pull/46
* This is under the non-default `pem` and `pkcs8` features
MSRV increased to `1.65.0`.
# 3.1.0
* Add no_std support by @pvdrz in https://github.com/ZcashFoundation/ed25519-zebra/pull/57
# 3.0.0
* Fix typo by @rex4539 in https://github.com/ZcashFoundation/ed25519-zebra/pull/32
* Add Zeroize impl for SigningKey by @kim in https://github.com/ZcashFoundation/ed25519-zebra/pull/34
* Add JNI code for ed25519-zebra by @droark in https://github.com/ZcashFoundation/ed25519-zebra/pull/37
* Update rand_core to 0.6 and rand to 0.8 by @dconnolly in https://github.com/ZcashFoundation/ed25519-zebra/pull/44
* dependencies: update zeroize to 1.2 by @FintanH in https://github.com/ZcashFoundation/ed25519-zebra/pull/52
# 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.
