Bump MSRV to 1.56.1 As we have done in other parts of the ecosystem bump the MSRV to Rust `v1.56.1`. Done for `secp256k1` and `secp256k1-sys`.
2024-03-26 23:20:53 +00:00
# Unreleased
Deprecate ThirtyTwoByteHash The implementations of `ThirtyTwoByteHash` for types from the `hashes` crate are problematic during upgrades because both `bitcoin` and `secp256k1` depend on `hashes` and when the versions of `hashes` get out of sync usage of the trait breaks. Deprecate the `ThirtyTwoByteHash` trait and remove the impls for types from `bitcoin_hashes`. Add an explanation in the changelog because its too long to go in the deprecation message.
2024-04-01 22:07:08 +00:00
* Deprecate `ThirtyTwoByteHash`
This trait turned out to be problematic during upgrade because we support a ranged dependency for
`bitcoin_hashes`. Consider implementing `From<T> for Message` for your type iff your type is a 32
byte hash (ie, output from a hash algorithm that produces a 32 byte digest like sha256). When
using the impl, consider using `Message::from` instead of `hash.into()` because we will be
introducing generics in a future version and the compiler will not be able to work out the target
type.
Bump MSRV to 1.56.1 As we have done in other parts of the ecosystem bump the MSRV to Rust `v1.56.1`. Done for `secp256k1` and `secp256k1-sys`.
2024-03-26 23:20:53 +00:00
* Bump MSRV to Rust `v1.56.1`
Upgrade hashes dependency Keep the range versioning but increase the threshould to include the upcoming `v0.14.0` release.
2024-03-21 04:54:32 +00:00
* Upgrade `hashes` using range dependency `version = ">= 0.12, <= 0.14"`.
Bump MSRV to 1.56.1 As we have done in other parts of the ecosystem bump the MSRV to Rust `v1.56.1`. Done for `secp256k1` and `secp256k1-sys`.

secp256k1: Remove custom implementations of Eq, Ord and friends Now that we have Rust 1.48 as the MSRV we no longer need the custom implementations of `PartialEq`, `Eq`, `PartialOrd`, `Ord`, and `Hash`. We can just let users of the `impl_array_newtype` macro derive these traits if they want them. Remove the custom implementations and add derives to our two users of the macro.
2023-03-30 22:23:49 +00:00
* Remove implementations of `PartialEq`, `Eq`, `PartialOrd`, `Ord`, and `Hash` from the

Add changelog entry for removal of ONE_KEY In the 0.25.0 release we removed the `ONE_KEY` const but did not mention it in the release notes. This makes upgrade harder than it should be. In hindsight we should have deprecated the const then removed it. Add a changelog entry to the 0.25.0 release mentioning the removal and the work around.

Bump version number to v0.24.1 We have fixed a bug in `KeyPair` decoding and otherwise didn't change the API.
2022-10-25 18:32:58 +00:00
# 0.24.1 - 2022-10-25
* [Fix broken deserialization logic of `KeyPair`](https://github.com/rust-bitcoin/rust-secp256k1/issues/491) that previously always panicked. After the patch deserialization only panics if neither the `global-context` nor the `alloc` (default) feature is active.
Bump version number to v0.24.0 We have updated the `bitcoin_hashes` version, this requires a minor version bump and release.
2022-07-18 23:08:12 +00:00

# 0.23.0 - 2022-06-21
The major change in this version is the increase of the Minimum Supported Rust Version (MSRV) from 1.29 to 1.41.1, this is a big change because it introduces Rust Edition 2018 to the codebase along with all the benefits that brings.
## Breaking changes
* [MSRV bumped to 1.41.1 and edition changed to 2018](https://github.com/rust-bitcoin/rust-secp256k1/pull/331)
* serde implements serialize [fixed-width arrays](https://github.com/rust-bitcoin/rust-secp256k1/pull/406) as tuples in binary formats to avoid encoding the length
* Key tweaking methods renamed and refactored to use a more [functional-style](https://github.com/rust-bitcoin/rust-secp256k1/pull/406), they now accept a [new Scalar](https://github.com/rust-bitcoin/rust-secp256k1/pull/445) type instead of raw slices
* Update [`rand` dependency to 0.8](https://github.com/rust-bitcoin/rust-secp256k1/pull/331)
* `KeyPair::from_secret_key` [borrows SecretKey](https://github.com/rust-bitcoin/rust-secp256k1/pull/430) instead of taking ownership
Removed `Default` from `SerializedSignature` `Default` was pointless, so it was replaced with internal `from_raw_parts` method which also checks the length. This commit also documents changes to `SerializedSignature`. Closes #454
2022-06-21 22:29:57 +00:00
* `SerializedSignature` no longer implements `Default`
Bump crate version to 0.23.0 In preparation for release, write CHANGELOG release notes and bump the crate version to 0.23.0
2022-06-09 05:48:15 +00:00
## New features/APIs
* Several convenience/conversion methods between [keys](https://github.com/rust-bitcoin/rust-secp256k1/pull/430)
* [`sign_ecdsa_with_noncedata` and `sign_ecdsa_recoverable_with_noncedata`](https://github.com/rust-bitcoin/rust-secp256k1/pull/425) can be used to add additional entropy to ECDSA signatures
* Errors now display their sources if std is unavailable, with std they rely on the consumer to use the source() method
* [Implemented `TryFrom` for `Parity`](https://github.com/rust-bitcoin/rust-secp256k1/pull/409)
* The [alloc feature](https://github.com/rust-bitcoin/rust-secp256k1/pull/331) can be used on targets with allocators without a standard library
* `SharedSecret` can be created from a slice, parsed from a hex string, or [(de)serialized using serde](https://github.com/rust-bitcoin/rust-secp256k1/pull/418)
Removed `Default` from `SerializedSignature` `Default` was pointless, so it was replaced with internal `from_raw_parts` method which also checks the length. This commit also documents changes to `SerializedSignature`. Closes #454
2022-06-21 22:29:57 +00:00
* `SerializedSignature` implements `IntoIterator` (both owned and shared reference)

* We now [derive `std::hash::Hash` for `Signature`](https://github.com/rust-bitcoin/rust-secp256k1/pull/441)
## Other improvements

* `githooks/` directory added for contributors
* [Clippy is now used in CI](https://github.com/rust-bitcoin/rust-secp256k1/pull/448) and the code is clippy-compliant
* Various documentation improvements

rust-secp 0.20.0
2020-12-21 22:16:23 +00:00
# 0.20.0 - 2020-12-21
* [remove `ffi::PublicKey::blank`](https://github.com/rust-bitcoin/rust-secp256k1/pull/232) and replace with unsafe [`ffi::PublicKey::new` and `ffi::PublicKey::from_array_unchecked`](https://github.com/rust-bitcoin/rust-secp256k1/pull/253/); similar for all other FFI types
* [support wasm32-wasi target](https://github.com/rust-bitcoin/rust-secp256k1/pull/242)
* [make the global-context feature depend on the rand-std feature](https://github.com/rust-bitcoin/rust-secp256k1/pull/246)
* [add a lexicographic ordering to `PublicKey`](https://github.com/rust-bitcoin/rust-secp256k1/pull/248) which does **not** match the ordering used by Bitcoin Core (matching this would be impossible as it requires tracking a compressedness flag, which libsecp256k1 does not have)

* [require use of new `AlignedType` in preallocated-context API to enforce alignment requirements](https://github.com/rust-bitcoin/rust-secp256k1/pull/233); previously it was possible to get UB by using misaligned memory stores
* [enforce correct alignment when using preallocated context API](https://github.com/rust-bitcoin/rust-secp256k1/pull/233)
* [stop using cargo features for dangerous build-breaking options, require setting `RUSTFLAGS` instead](https://github.com/rust-bitcoin/rust-secp256k1/pull/263)
* [implement low-R signing and function to grind even smaller signatures](https://github.com/rust-bitcoin/rust-secp256k1/pull/259)
* [remove endomorphism feature, following upstream in enabling it by default](https://github.com/rust-bitcoin/rust-secp256k1/pull/257)

significantly less memory for the validation context (~680B instead of
~520kB), at the cost of slower validation. It does not affect the speed of
signing, nor the size of the signing context.
