+# Changelog
+
+Entries are listed in reverse chronological order.
+
+## 2.4.1
+
+* Fix a bug in how the README was included in the documentation builds
+ which caused nightly builds to break.
+
+## 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 `CtOption`s 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.
