# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/) and this project
adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).
## [3.0.0] - 2024-04-28
### Changed
- Make `OrdSet::get_prev` and `OrdSet::get_next` more generic, using the `Borrow` trait.
## [2.0.3] - 2023-10-25
### Changed
- `Vector::truncate` no longer panics if the `len` argument is larger than the
vector's length (instead it does nothing)
- Added `OrdSet::get` to align with `std::collections::BTreeSet` and make it possible
to get values in the set by using a borrowed form of the element.
## [2.0.2] - 2023-08-19
### Changed
- Some unnecessary trait bounds on `HashMap` were removed.
## [2.0.1] - 2022-04-19
### Deprecated
- The `difference` alias for `symmetric_difference` has been deprecated.
To avoid conflicting with the *std* library where `difference` is equivalent
to *imbl*'s `relative_complement`.
## [2.0.0] - 2022-04-12
### Fixed
- Fixed several critical bugs in `Vector` (see PRs #34 and #37).
- Removed `Hash` and `PartialOrd` impls for `HashMap` and `HashSet`.
- Made all container types covariant in their type parameters.
### Added
- Added `Vector::insert_ord_by` and `Vector::insert_ord_by_key`
- Added `From` impls from arrays.
## [1.0.1] - 2021-08-12
### Fixed
- Fixed #18, a critical bug that prevented everything from being `Send` and `Sync`.
- Fixed value priority of unions in `OrdMap` and `HashMap`: the values in `self` should always win.
## [1.0.0] - 2021-08-11
This is the initial release of `imbl`, our fork/continuation of `im`. It is
fully compatible with version `15.0.0` of `im`, and this changelog only lists
those things which have changed since the fork.
### Fixed
- Fixed bugs when deleting elements from large `OrdMap`s and `OrdSet`s
- Fixed bugs where iterating over `OrdMap`s and `OrdSet`s could skip some elements.
