Changelog

Entries are listed in reverse chronological order.

2.5.0

Update to new stable #![doc = include_str!], by @delta1. This fixes a compile issue caused by the use of the older #![doc(include(...))] syntax. This also bumps the MSRV to 1.54.

2.4.1

Add a note to the README about crate seizures.

2.4.0

Add new ConstantTimeGreater and ConstantTimeLess traits, as well as implementations for unsigned integers, by @isislovecruft.

2.3.0

Add impl ConstantTimeEq for Choice by @tarcieri.
Add impl From<CtOption<T>> for Option<T> by @CPerezz. This is useful for handling library code that produces CtOptions in contexts where timing doesn't matter.
Introduce an MSRV policy.

2.2.3

Remove the nightly-only asm-based black_box barrier in favor of the volatile-based one, fixing compilation on current nightlies.

2.2.2

Update README.md to clarify that 2.2 and above do not require the nightly feature.

2.2.1

Adds an or_else combinator for CtOption, by @ebfull.
Optimized black_box for nightly, by @jethrogb.
Optimized black_box for stable, by @dsprenkels.
Fixed CI for no_std, by @dsprenkels.
Fixed fuzz target compilation, by @3for.

2.2.0

Error during cargo publish, yanked.

2.1.1

Adds the "crypto" tag to crate metadata.
New shorter, more efficient ct_eq() for integers, contributed by Thomas Pornin.

2.1.0

Adds a new CtOption<T> which acts as a constant-time Option<T> (thanks to @ebfull for the implementation).
Choice now itself implements ConditionallySelectable.

2.0.0

Stable version with traits reworked from 1.0.0 to interact better with the orphan rules.
