|
|
|
|
Move crate from [original repo](https://github.com/rust-bitcoin/bitcoin_hashes) to the
|
|
`rust-bitcoin` repository. Commit history was lost during move, for commit history see the original
|
|
repository. Tip of bitcoin_hashes:master at time of import: 54c16249e06cc6b7870c7fc07d90f489d82647c7

# 0.11.0 - 2022-06-25
|
|
|
|
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. We also did a bunch of optimisations to speed up encoding and
|
|
decoding hex strings.
|
|
|
|
## Breaking changes
|
|
|
|
* [Enable edition 2018 and bump MSRV to Rust 1.41.1](https://github.com/rust-bitcoin/bitcoin_hashes/pull/136)
|
|
|
|
## New features/APIs
|
|
|
|
* [Add `all_zeros` to `Hash` trait](https://github.com/rust-bitcoin/bitcoin_hashes/pull/148)
|
|
* [Implement `Write` on `HmacEngine`](https://github.com/rust-bitcoin/bitcoin_hashes/pull/133)
|
|
* [Introduce `HexWriter`](https://github.com/rust-bitcoin/bitcoin_hashes/pull/156), makes serialising hex faster
|
|
* [Implement `Read` on `HexIterator`](https://github.com/rust-bitcoin/bitcoin_hashes/pull/135), makes deserialising hex faster
|
|
|
|
## Other improvements
|
|
|
|
* Use `rotate_left` [instead of custom macro](https://github.com/rust-bitcoin/bitcoin_hashes/pull/162)
|
|
* [Enable clippy on CI](https://github.com/rust-bitcoin/bitcoin_hashes/pull/152)
|
|
* Various docs fixes
|
|
* [Improve feature test coverage](https://github.com/rust-bitcoin/bitcoin_hashes/pull/147)
|
|
* [Add a disabled `rustfmt.toml`](https://github.com/rust-bitcoin/bitcoin_hashes/pull/141) to improve interaction with auto-formatting in editors
|
|
|
|
|
|
# 0.10.0 - 2021-07-05
|
|
|
|
* Increase `core2` to released version of 0.3.0
|
|
|
|
# 0.9.7 - 2021-06-17
|
|
|
|
* Introduce `alloc` feature and `core2` dependency for nostd support (this feature has MSRV of 1.36 rather than 1.29)
|
|
|
|
# 0.9.6 - 2021-05-03
|
|
|
|
* Re-export `core` as `_export::_core`. This resolves an issue when calling several exported macros with the `std` feature.
|
|
|
|
# 0.9.5 - 2021-04-28
|
|
|
|
* Add [`#[repr(transparent)]` to all newtype wrappers](https://github.com/rust-bitcoin/bitcoin_hashes/pull/108/)
|
|
* Add [missing `#derive`s](https://github.com/rust-bitcoin/bitcoin_hashes/pull/110/)
|
|
* Replace `fuzztarget` feature with [use of `cfg(fuzzing)`](https://github.com/rust-bitcoin/bitcoin_hashes/pull/111/)
|
|
* Use [`core` rather than `std`](https://github.com/rust-bitcoin/bitcoin_hashes/pull/118/) and [fix `no_std` compilation](https://github.com/rust-bitcoin/bitcoin_hashes/pull/122/)
|
|
|
|
Note that we have stopped re-exporting the `core` crate when compiling without `std`. This is technically a breaking change but it is hard to imagine what user might be affected.
