+## [0.3.1] - 2019-08-06
+- Drop `byteorder`-dependency in favor of `stdlib`-implementation.
+
+## [0.3.0] - 2019-06-12
+- Bump minor crate version since rand_core bump is a breaking change
+- Switch to Edition 2018
+
+## [0.2.1] - 2019-06-06 - yanked
+- Bump `rand_core` version
+- Document crate features in README
+
+## [0.2.0] - 2019-05-28
+- Fix `seed_from_u64(0)` for `Xoroshiro64StarStar` and `Xoroshiro64Star`. This
+ breaks value stability for these generators if initialized with `seed_from_u64`.
+- Implement Serde support.
+
## [0.1.0] - 2019-01-04
Initial release.
