* [breaking change] Use `MaybeUninit` internally to avoid possible undefined behavior (servo#162, servo#170).
* [breaking change] The `drain` method now takes a range argument, just like the standard `Vec::drain` (servo#145).
* [breaking change] Remove the `unreachable` function and replace it with the new standard `unreachable_unchecked` function (servo#164).
* [breaking change] Use `no_std` by default. This crate depends only on `core` and `alloc` by default. If the optional `write` feature is enabled then it depends on `std` so that `SmallVec<[u8, _]>` can implement the `std::io::Write` trait (servo#173).
* Add support for 96-element small vectors, `SmallVec<[T; 96]>` (servo#163).
* Iterators now implement `FusedIterator` (servo#172).
* Indexing now uses the standard `SliceIndex` trait (servo#166).
* Remove the deprecated `VecLike` trait (servo#165).
* Use `NonNull` internally (servo#171).
* Add automatic fuzz testing and MIRI testing (servo#168, servo#162).
* Update syntax and formatting to Rust 2018 standard (servo#174, servo#167).
