- `DefaultRng` type alias added to public API
## 0.7.1
### Notable Internal Changes
- [[#80](#80)] Added a default set of features to enable `ed2559-dalek`s 64 bit backend and added a `wasm` feature that will instead use a 32 bit backend
## 0.7.0
### Public API changes
- [[#57](#57)]
- `api::Api` renamed to `api::Recrypt`
- `api_480::Api480` renamed to `api_480::Recrypt480`
- `ApiErr` renamed to `RecryptErr` and `RecryptErr` is now publicly exported
- `PrivateKey::ENCODED_SIZE_BYTES` is now pub
- [[#63](#63)] Added a prelude for easier importing of common types and traits
- `use recrypt::prelude::*`
- [[#70](#70)]
- `DerivedSymmetricKey` now has a `to_private_key`
- `PublicKey` APIs now take all arguments as borrows
- [[#71](#71)]
- provide `From<SigningKeyPair>` instance for `[u8; 64]`
- provide `Clone` for `PrivateKey`
- many wrapped byte types can be consumed to get the underlying bytes out without copying
- [[#72](#72)] `PublicSigningKey`'s `bytes()` method now returns a reference instead of copying
## 0.6.2
### Notable Internal Changes
- [[#54](#54)] Consume gridiron 0.6.0, which fixes some perf issues.
- [[#55](#55)] Optimize inverse, xi multiplications, etc.
## 0.6.1
### Notable Internal Changes
- [[#47](#47)] Document HomogeneousPoint / TwistedHPoint normalize behavior and remove panic from pairing
- [[#50](#50)] Update to use Monty represenation for all 256 bit operations.
- [[#52](#52)] Update to use Monty represenation for all 480 bit operations.
## 0.6.0
### Public API changes
* [[#35](#35)] 480-bit public API available. See api_480.rs
### Notable Internal Changes
- [[#27](#27)] Use Rust 2018 edition
- Progress toward Constant Time algorithms
* [[#42](#42)] Fp `is_one` and `is_zero` documented to not be constant time
* [[#40](#40)] Fp `Mul<u64>` and `Add<u64>` now use `u32` and are documented to not be constant time
* [[#39](#39)] Point negation is constant time
* [[#37](#37)] Fp12/6 `to_fp2` constant time behavior documented
* [[#26](#26)] Point double and add functions are constant time
## 0.5.1
