# 0.20.3 - 2021-06-10
* Fix [`SecretKey` validation in `from_str`](https://github.com/rust-bitcoin/rust-secp256k1/pull/296)
* Add [`global-context-less-secure` feature](https://github.com/rust-bitcoin/rust-secp256k1/pull/279) which creates a non-randomized global context (and does not require `rand` or `std`)
* Add [`schnorrsig::KeyPair::from_secret_key` convenience function](https://github.com/rust-bitcoin/rust-secp256k1/pull/294)
* Add [`combine_keys` function to `PublicKey`](https://github.com/rust-bitcoin/rust-secp256k1/pull/291)

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)
* [implement BIP340 Schnorr signatures](https://github.com/rust-bitcoin/rust-secp256k1/pull/237)
* [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)

2020-08-26 20:26:14 +00:00
# 0.18.0 - 2020-08-26
* Add feature-gated `bitcoin_hashes` dependency and [`ThirtyTwoByteHash` trait](https://github.com/rust-bitcoin/rust-secp256k1/pull/206/)

2020-08-26 20:26:14 +00:00
* Allow [all-zero messages](https://github.com/rust-bitcoin/rust-secp256k1/pull/207) to be constructed

# 0.17.2
- Fix linking in the `fuzztarget` feature.
2019-12-11 17:50:23 +00:00
# 0.17.1
- Correctly prefix the secp256k1-sys links field in Cargo.toml.
2019-12-05 15:17:08 +00:00
# 0.17.0
- Move FFI into secp256k1-sys crate.
- Add `external-symbols` feature for not building upstream.
- Add functions to create a context from a raw pointer.
- Support passing custom hash functions to ECDH.
- Wrap Secp256k1 from raw context in a ManuallyDrop.
2019-09-06 16:15:49 +00:00
# 0.15.4 - 2019-09-06
- Add `rand-std` feature.
- Pin the cc build-dep version to `< 1.0.42` to remain
compatible with rustc 1.22.0.
- Changed all `as_*ptr()` to a new safer `CPtr` trait
# 0.15.2 - 2019-08-08
- Add feature `lowmemory` that reduces the EC mult window size to require
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.
2019-07-25 13:06:07 +00:00

2019-07-08 13:57:52 +00:00
# 0.14.0 - 2019-07-08

* Got full no-std support including eliminating all use of libc in C bindings.
[PR 1](https://github.com/rust-bitcoin/rust-secp256k1/pull/115)
[PR 2](https://github.com/rust-bitcoin/rust-secp256k1/pull/125).
This library should be usable in bare-metal environments and with rust-wasm.
Thanks to Elichai Turkel for driving this forward!

2018-12-03 13:51:42 +00:00
# 0.12.0 - 2018-12-03
2018-12-03 13:51:42 +00:00

2018-08-22 16:39:36 +00:00
# 0.11.0 - 2018-08-22
2018-07-30 03:03:20 +00:00
* Update `rand` to 0.4 and `gcc` 0.3 to `cc` 1.0. (`rand` 0.5 exists but has a lot of breaking changes and no longer compiles with 1.14.0.)
2018-08-15 16:29:23 +00:00
* Remove `PublicKey::combine` from API since it cannot be used with anything else in the API

* [Remove `PublicKey::new()` and `PublicKey::is_valid()`](https://github.com/rust-bitcoin/rust-secp256k1/pull/37) since `new` was unsafe and it should now be impossible to create invalid `PublicKey` objects through the API
* [Reintroduce serde support](https://github.com/rust-bitcoin/rust-secp256k1/pull/38) behind a feature gate using serde 1.0
* Clean up build process and various typos
