+
+# Release 0.1.40 (2019-05-20)
+
+- [Optimized primitive `gcd` by avoiding memory swaps][11].
+- [Fixed `lcm(0, 0)` to return `0`, rather than panicking][18].
+- [Added `Integer::div_ceil`, `next_multiple_of`, and `prev_multiple_of`][16].
+- [Added `Integer::gcd_lcm`, `extended_gcd`, and `extended_gcd_lcm`][19].

+# Release 0.1.39 (2018-06-20)
+
+- [The new `Roots` trait provides `sqrt`, `cbrt`, and `nth_root` methods][9],
+  calculating an `Integer`'s principal roots rounded toward zero.
+

+
+# Release 0.1.38 (2018-05-11)
+
+- [Support for 128-bit integers is now automatically detected and enabled.][8]
+  Setting the `i128` crate feature now causes the build script to panic if such
+  support is not detected.

+
+# Release 0.1.37 (2018-05-10)
+
+- [`Integer` is now implemented for `i128` and `u128`][7] starting with Rust
+  1.26, enabled by the new `i128` crate feature.

+**Contributors**: @cuviper

+
+# Release 0.1.36 (2018-02-06)
+
+- [num-integer now has its own source repository][num-356] at [rust-num/num-integer][home].
+- [Corrected the argument order documented in `Integer::is_multiple_of`][1]
+- [There is now a `std` feature][5], enabled by default, along with the implication
+  that building *without* this feature makes this a `#[no_std]` crate.
+  - There is no difference in the API at this time.
