-## [0.6.0] - Unreleased
-
-### Crate features and organisation
-- The ISAAC and Xorshift RNGs have been moved to their own crates: `rand_isaac`
-  and `rand_xorshift`. (#551, #557)
+You may also find the [Upgrade Guide](https://rust-random.github.io/book/update.html) useful.
+
+
+## [0.6.1] - 2018-11-22
+- Support sampling `Duration` also for `no_std` (only since Rust 1.25) (#649)
+- Disable default features of `libc` (#647)
+
+## [0.6.0] - 2018-11-14
+
+### Project organisation
+- Rand has moved from [rust-lang-nursery](https://github.com/rust-lang-nursery/rand)
+  to [rust-random](https://github.com/rust-random/rand)! (#578)
+- Created [The Rust Random Book](https://rust-random.github.io/book/)
+  ([source](https://github.com/rust-random/book))
+- Update copyright and licence notices (#591, #611)
+- Migrate policy documentation from the wiki (#544)
+
+### Platforms
+- Add fork protection on Unix (#466)
+- Added support for wasm-bindgen. (#541, #559, #562, #600)
+- Enable `OsRng` for powerpc64, sparc and sparc64 (#609)
+- Use `syscall` from `libc` on Linux instead of redefining it (#629)
+
+### RNGs
+- Switch `SmallRng` to use PCG (#623)
+- Implement `Pcg32` and `Pcg64Mcg` generators (#632)
+- Move ISAAC RNGs to a dedicated crate (#551)
+- Move Xorshift RNG to its own crate (#557)
+- Move ChaCha and HC128 RNGs to dedicated crates (#607, #636)
+- Remove usage of `Rc` from `ThreadRng` (#615)
+
+### Sampling and distributions
+- Implement `Rng.gen_ratio()` and `Bernoulli::new_ratio()` (#491)
+- Make `Uniform` strictly respect `f32` / `f64` high/low bounds (#477)
+- Allow `gen_range` and `Uniform` to work on non-`Copy` types (#506)
 - `Uniform` supports inclusive ranges: `Uniform::from(a..=b)`. This is
   automatically enabled for Rust >= 1.27. (#566)
-- Support for `i128` and `u128` is automatically enabled for Rust >= 1.26. This
-  renders the `i128_support` feature obsolete. It still exists for backwards
-  compatibility but does not have any effect. This breaks programs using Rand
-  with `i128_support` on nightlies older than Rust 1.26. (#571)
+- Implement `TrustedLen` and `FusedIterator` for `DistIter` (#620)
 
-### New distributions
+#### New distributions
+- Add the `Dirichlet` distribution (#485)
 - Added sampling from the unit sphere and circle. (#567)
+- Implement the triangular distribution (#575)
+- Implement the Weibull distribution (#576)
+- Implement the Beta distribution (#574)
 
-### Sequences module
+#### Optimisations
+
+- Optimise `Bernoulli::new` (#500)
+- Optimise `char` sampling (#519)
+- Optimise sampling of `std::time::Duration` (#583)
+
+### Sequences
+- Redesign the `seq` module (#483, #515)
+- Add `WeightedIndex` and `choose_weighted` (#518, #547)
 - Optimised and changed return type of the `sample_indices` function. (#479)
-- Added weighted sampling. (#518)
+- Use `Iterator::size_hint()` to speed up `IteratorRandom::choose` (#593)
 
-### Platform support
-- Added support for wasm-bindgen. (#541)
-- Added basic SIMD support. (#523)
+### SIMD
+- Support for generating SIMD types (#523, #542, #561, #630)
+
+### Other
+- Revise CI scripts (#632, #635)
+- Remove functionality already deprecated in 0.5 (#499)
+- Support for `i128` and `u128` is automatically enabled for Rust >= 1.26. This
+  renders the `i128_support` feature obsolete. It still exists for backwards
+  compatibility but does not have any effect. This breaks programs using Rand
+  with `i128_support` on nightlies older than Rust 1.26. (#571)
