by @Xaeroxe + - Added combinatory iterator adaptors: + - [`.permutations(k)`](https://docs.rs/itertools/0.8.1/itertools/trait.Itertools.html#method.permutations): + + `[0, 1, 2].iter().permutations(2)` yields + + ```rust + [ + vec![0, 1], + vec![0, 2], + vec![1, 0], + vec![1, 2], + vec![2, 0], + vec![2, 1], + ] + ``` + + ;

by @Emerentius +## 0.8.0 + - Added new adaptor `.map_into()` for conversions using `Into` by @vorner + - Improved `Itertools` docs by @JohnHeitmann + - The return type of `.sorted_by_by_key()` is now an iterator, not a Vec. + - The return type of the `izip!(x, y)` macro with exactly two arguments is now the usual `Iterator::zip`. + - Remove `.flatten()` in favour of std's `.flatten()` + - Deprecate `.foreach()` in favour of std's `.for_each()` + - Deprecate `.step()` in favour of std's `.step_by()` + - Deprecate `repeat_call` in favour of std's `repeat_with` + - Deprecate `.fold_while()` in favour of std's `.try_fold()` + - Require Rust 1.24 as minimal version. +## 0.7.11 + - Add convenience methods to `EitherOrBoth`, making it more similar to `Option` and `Either` by @jethrogb +## 0.7.10 + - No changes. +## 0.7.9 + - New inclusion policy: See the readme about suggesting features for std before accepting them in itertools. + - The `FoldWhile` type now implements `Eq` and `PartialEq` by @jturner314 +## 0.7.8 + - Add new iterator method `.tree_fold1()` which is like `.fold1()` except items are combined in a tree structure (see its docs). By @scottmcm + - Add more `Debug` impls by @phimuemue: KMerge, KMergeBy, MergeJoinBy, ConsTuples, Intersperse, ProcessResults, RcIter, Tee, TupleWindows, Tee, ZipLongest, ZipEq, Zip. +## 0.7.7 + - Add new iterator method `.into_group_map() -> HashMap>` which turns an iterator of `(K, V)` elements into such a hash table, where values are grouped by key. By @tobz1000 + - Add new free function `flatten` for the `.flatten()` adaptor. **NOTE:** recent Rust nightlies have `Iterator::flatten` and thus a clash with our flatten adaptor.

This means it optimizes as well as the standard library `.zip()` it uses. **Note:** `multizip` and `izip!()` are now different! The former has a named type but the latter optimizes better. + - Faster `.unique()` + - `no_std` support, which is opt-in! + - Many lovable features are still there without std, like `izip!()` or `.format()` or `.merge()`, but not those that use collections. + - Trait bounds were required up front instead of just on the type: `group_by`'s `PartialEq` by @Phlosioneer and `repeat_call`'s `FnMut`. + - Removed deprecated constructor `Zip::new` — use `izip!()` or `multizip()` +## 0.6.5 + - Fix bug in `.cartesian_product()`'s fold (which only was visible for unfused iterators). +## 0.6.4 + - Add specific `fold` implementations for `.cartesian_product()` and `cons_tuples()`, which improves their performance in fold, foreach, and iterator consumers derived from them. +## 0.6.3 + - Add iterator adaptor `.positions(predicate)` by @tmccombs +## 0.6.2 + - Add function `process_results` which can “lift” a function of the regular values of an iterator so that it can process the `Ok` values from an iterator of `Results` instead, by @shepmaster + - Add iterator method `.concat()` which combines all iterator elements into a single collection using the `Extend` trait, by @srijs +## 0.6.1 + - Better size hint testing and subsequent size hint bugfixes by @rkarp. Fixes bugs in product, `interleave_shortest` size hints. + - New iterator method `.all_equal()` by @phimuemue +## 0.6.0 + - Deprecated names were removed in favour of their replacements + - `.flatten()` does not implement double ended iteration anymore + - `.fold_while()` uses `&mut self` and returns `FoldWhile`, for composability #168 + - `.foreach()` and `.fold1()` use `self`, like `.fold()` does. + - `.combinations(0)` now produces a single empty vector. #174 +## 0.5.10 + - Add itertools method `.kmerge_by()` (and corresponding free function) + - Relaxed trait requirement of `.kmerge()` and `.minmax()` to PartialOrd. +## 0.5.9 + - Add multipeek method `.reset_peek()` + - Add categories +## 0.5.8 + - Add iterator adaptor `.peeking_take_while()` and its trait `PeekingNext`. +## 0.5.7 + - Add iterator adaptor `.with_position()` + - Fix multipeek's performance for long peeks by using `VecDeque`. +## 0.5.6 + - Add `.map_results()` +## 0.5.5 + - Many more adaptors now implement `Debug` + - Add free function constructor `repeat_n`. `RepeatN::new` is now deprecated. +## 0.5.4 + - Add infinite generator function `iterate`, that takes a seed and a closure. +## 0.5.3 + - Special-cased `.fold()` for flatten and put back. `.foreach()` now uses fold on the iterator, to pick up any iterator specific loop implementation. + - `.combinations(n)` asserts up front that `n != 0`, instead of running into an error on the second iterator element. +## 0.5.2 + - Add `.tuples::()` that iterates by two, three or four elements at a time (where `T` is a tuple type). + - Add `.tuple_windows::()` that iterates using a window of the two, three or four most recent elements. + - Add `.next_tuple::()` method, that picks the next two, three or four elements in one go. + - `.interleave()` now has an accurate size hint. +## 0.5.1 + - Workaround module/function name clash that made racer crash on completing itertools. Only internal changes needed. +## 0.5.0 + - [Release announcement](https://bluss.github.io/rust/2016/09/26/itertools-0.5.0/) + - Renamed: + - `combinations` is now `tuple_combinations` + - `combinations_n` to `combinations` + - `group_by_lazy`, `chunks_lazy` to `group_by`, `chunks` + - `Unfold::new` to `unfold()` + - `RepeatCall::new` to `repeat_call()` + - `Zip::new` to `multizip` + - `PutBack::new`, `PutBackN::new` to `put_back`, `put_back_n` + - `PutBack::with_value` is now a builder setter, not a constructor + - `MultiPeek::new`, `.multipeek()` to `multipeek()` + - `format` to `format_with` and `format_default` to `format` + - `.into_rc()` to `rciter` + - `Partition` enum is now `Either` + - Module reorganization: + - All iterator structs are under `itertools::structs` but also reexported to the top level, for backwards compatibility + - All free functions are reexported at the root, `itertools::free` will be removed in the next version + - Removed: + - `ZipSlices`, use `.zip()` instead + - `.enumerate_from()`, `ZipTrusted`, due to being unstable + - `.mend_slices()`, moved to crate `odds` + - Stride, StrideMut, moved to crate `odds` + - `linspace()`, moved to crate `itertools-num` + - `.sort_by()`, use `.sorted_by()` + - `.is_empty_hint()`, use `.size_hint()` + - `.dropn()`, use `.dropping()` + - `.map_fn()`, use `.map()` + - `.slice()`, use `.take()` / `.skip()` + - helper traits in `misc` + - `new` constructors on iterator structs, use `Itertools` trait or free functions instead + - `itertools::size_hint` is now private + - Behaviour changes: + - `format` and `format_with` helpers now panic if you try to format them more than once. + - `repeat_call` is not double ended anymore + - New features: + - tuple flattening iterator is constructible with `cons_tuples` + - itertools reexports `Either` from the `either` crate. `Either` is an iterator when `L, R` are. + - `MinMaxResult` now implements `Copy` and `Clone` + - `tuple_combinations` supports 1-4 tuples of combinations (previously just 2) +## 0.4.19 + - Add `.minmax_by()` + - Add `itertools::free::cloned` + - Add `itertools::free::rciter` + - Improve `.step(n)` slightly to take advantage of specialized Fuse better. +## 0.4.18 + - Only changes related to the "unstable" crate feature.
