+- 1.8.0
+
+  - The new `IndexMap::into_keys` and `IndexMap::into_values` will consume

+    methods, by @taiki-e in PR [195].
+
+  - More of the iterator types implement `Debug`, `ExactSizeIterator`, and
+    `FusedIterator`, by @cuviper in PR [196].
+
+  - `IndexMap` and `IndexSet` now implement rayon's `ParallelDrainRange`,
+    by @cuviper in PR [197].
+
+  - `IndexMap::with_hasher` and `IndexSet::with_hasher` are now `const`
+    functions, allowing static maps and sets, by @mwillsey in PR [203].
+
+  - `IndexMap` and `IndexSet` now implement `From` for arrays, matching
+    Rust 1.56's implementation for `HashMap`, by @rouge8 in PR [205].
+
+  - `IndexMap` and `IndexSet` now have methods `sort_unstable_keys`,
+    `sort_unstable_by`, `sorted_unstable_by`, and `par_*` equivalents,

+
+  - The `hashbrown` dependency has been updated to version 0.11.
+
+- 1.6.2
+

+
+- 1.3.2
+
+  - Maintenance update to regenerate the published `Cargo.toml`.
+
+- 1.3.1
+
+  - Maintenance update for formatting and `autocfg` 1.0.
+
+- 1.3.0
+
+  - The deprecation messages in the previous version have been removed.
+    (The methods have not otherwise changed.) Docs for removal methods have been
+    improved.
+  - From Rust 1.36, this crate supports being built **without std**, requiring
+    `alloc` instead. This is enabled automatically when it is detected that
+    `std` is not available. There is no crate feature to enable/disable to
+    trigger this. The new build-dep `autocfg` enables this.
+
+- 1.2.0
+
+  - Plain `.remove()` now has a deprecation message, it informs the user
+    about picking one of the removal functions `swap_remove` and `shift_remove`
+    which have different performance and order semantics.
+    Plain `.remove()` will not be removed, the warning message and method
+    will remain until further.
+
+  - Add new method `shift_remove` for order preserving removal on the map,
+    and `shift_take` for the corresponding operation on the set.
+
+  - Add methods `swap_remove`, `swap_remove_entry` to `Entry`.
+
+  - Fix indexset/indexmap to support full paths, like `indexmap::indexmap!()`
+
+  - Internal improvements: fix warnings, deprecations and style lints
+
+- 1.1.0
+
+  - Added optional feature `"rayon"` that adds parallel iterator support
+    to `IndexMap` and `IndexSet` using Rayon. This includes all the regular
+    iterators in parallel versions, and parallel sort.
+
+  - Implemented `Clone` for `map::{Iter, Keys, Values}` and
+    `set::{Difference, Intersection, Iter, SymmetricDifference, Union}`
+
+  - Implemented `Debug` for `map::{Entry, IntoIter, Iter, Keys, Values}` and
+    `set::{Difference, Intersection, IntoIter, Iter, SymmetricDifference, Union}`
+
+  - Serde trait `IntoDeserializer` are implemented for `IndexMap` and `IndexSet`.
+
+  - Minimum Rust version requirement increased to Rust 1.30 for development builds.
+
+- 1.0.2
+
+  - The new methods `IndexMap::insert_full` and `IndexSet::insert_full` are
+    both like `insert` with the index included in the return value.
+
+  - The new method `Entry::and_modify` can be used to modify occupied
+    entries, matching the new methods of `std` maps in Rust 1.26.
+
+  - The new method `Entry::or_default` inserts a default value in unoccupied
+    entries, matching the new methods of `std` maps in Rust 1.28.
+
+- 1.0.1
+
+  - Document Rust version policy for the crate (see rustdoc)
+
+- 1.0.0
+
+  - This is the 1.0 release for `indexmap`! (the crate and datastructure
+    formerly known as “ordermap”)
+  - `OccupiedEntry::insert` changed its signature, to use `&mut self` for
+    the method receiver, matching the equivalent method for a standard
+    `HashMap`.  Thanks to @dtolnay for finding this bug.
+  - The deprecated old names from ordermap were removed: `OrderMap`,
+    `OrderSet`, `ordermap!{}`, `orderset!{}`. Use the new `IndexMap`
+    etc names instead.
+
+- 0.4.1
+
+  - Renamed crate to `indexmap`; the `ordermap` crate is now deprecated
+    and the types `OrderMap/Set` now have a deprecation notice.
+
+- 0.4.0
+
+  - This is the last release series for this `ordermap` under that name,
+    because the crate is **going to be renamed** to `indexmap` (with types
+    `IndexMap`, `IndexSet`) and no change in functionality!
+  - The map and its associated structs moved into the `map` submodule of the
+    crate, so that the map and set are symmetric
+
+    + The iterators, `Entry` and other structs are now under `ordermap::map::`
+
+  - Internally refactored `OrderMap<K, V, S>` so that all the main algorithms
+    (insertion, lookup, removal etc) that don't use the `S` parameter (the
+    hasher) are compiled without depending on `S`, which reduces generics bloat.
+
+  - `Entry<K, V>` no longer has a type parameter `S`, which is just like
+    the standard `HashMap`'s entry.
+
+  - Minimum Rust version requirement increased to Rust 1.18
+
+- 0.3.5
+
+  - Documentation improvements
+
+- 0.3.4
+
+  - The `.retain()` methods for `OrderMap` and `OrderSet` now
+    traverse the elements in order, and the retained elements **keep their order**
+  - Added new methods `.sort_by()`, `.sort_keys()` to `OrderMap` and
+    `.sort_by()`, `.sort()` to `OrderSet`. These methods allow you to
+    sort the maps in place efficiently.
+
+- 0.3.3
+
+  - Document insertion behaviour better by @lucab
+  - Updated dependences (no feature changes) by @ignatenkobrain
+
+- 0.3.2
+
+  - Add `OrderSet` by @cuviper!
+  - `OrderMap::drain` is now (too) a double ended iterator.
+
+- 0.3.1
+
+  - In all ordermap iterators, forward the `collect` method to the underlying
+    iterator as well.
+  - Add crates.io categories.
+
+- 0.3.0
+
+  - The methods `get_pair`, `get_pair_index` were both replaced by
+    `get_full` (and the same for the mutable case).
+  - Method `swap_remove_pair` replaced by `swap_remove_full`.
+  - Add trait `MutableKeys` for opt-in mutable key access. Mutable key access
+    is only possible through the methods of this extension trait.
+  - Add new trait `Equivalent` for key equivalence. This extends the
+    `Borrow` trait mechanism for `OrderMap::get` in a backwards compatible
+    way, just some minor type inference related issues may become apparent.
+    See [#10] for more information.
+  - Implement `Extend<(&K, &V)>` by @xfix.
+
+[#10]: https://github.com/bluss/ordermap/pull/10
+
+- 0.2.13
+
+  - Fix deserialization to support custom hashers by @Techcable.
+  - Add methods `.index()` on the entry types by @garro95.
+
+- 0.2.12
+
+  - Add methods `.with_hasher()`, `.hasher()`.
+
+- 0.2.11
+
+  - Support `ExactSizeIterator` for the iterators. By @Binero.
+  - Use `Box<[Pos]>` internally, saving a word in the `OrderMap` struct.
+  - Serde support, with crate feature `"serde-1"`. By @xfix.
+
+- 0.2.10
+
+  - Add iterator `.drain(..)` by @stevej.
+
+- 0.2.9
+
+  - Add method `.is_empty()` by @overvenus.
+  - Implement `PartialEq, Eq` by @overvenus.
+  - Add method `.sorted_by()`.
+
+- 0.2.8
+
+  - Add iterators `.values()` and `.values_mut()`.
+  - Fix compatibility with 32-bit platforms.
+
+- 0.2.7
+
+  - Add `.retain()`.
+
+- 0.2.6
+
+  - Add `OccupiedEntry::remove_entry` and other minor entry methods,
+    so that it now has all the features of `HashMap`'s entries.
+
+- 0.2.5
+
+  - Improved `.pop()` slightly.
+
+- 0.2.4
+
+  - Improved performance of `.insert()` ([#3]) by @pczarn.
+
+[#3]: https://github.com/bluss/ordermap/pull/3
+
+- 0.2.3
+
+  - Generalize `Entry` for now, so that it works on hashmaps with non-default
+    hasher. However, there's a lingering compat issue since libstd `HashMap`
+    does not parameterize its entries by the hasher (`S` typarm).
+  - Special case some iterator methods like `.nth()`.
+
+- 0.2.2
+
+  - Disable the verbose `Debug` impl by default.
+
+- 0.2.1
+
+  - Fix doc links and clarify docs.
+
+- 0.2.0
+
+  - Add more `HashMap` methods & compat with its API.
+  - Experimental support for `.entry()` (the simplest parts of the API).
+  - Add `.reserve()` (placeholder impl).
+  - Add `.remove()` as synonym for `.swap_remove()`.
+  - Changed `.insert()` to swap value if the entry already exists, and
+    return `Option`.
+  - Experimental support as an *indexed* hash map! Added methods
+    `.get_index()`, `.get_index_mut()`, `.swap_remove_index()`,
+    `.get_pair_index()`, `.get_pair_index_mut()`.
+
+- 0.1.2
+
+  - Implement the 32/32 split idea for `Pos` which improves cache utilization
+    and lookup performance.
+
+- 0.1.1
+
+  - Initial release.
