## [Unreleased] - ReleaseDate
## [0.7.4] - 2021-03-16
### Added
- [PR#26](https://github.com/EmbarkStudios/cfg-expr/pull/26) added `Expression::original` to get the original string the expression was parsed from. Thanks [@gdesmott](https://github.com/gdesmott)!

## [0.7.3] - 2021-03-16
### Added
- [PR#25](https://github.com/EmbarkStudios/cfg-expr/pull/25) added `Clone` for `Expression`. Thanks [@gdesmott](https://github.com/gdesmott)!
## [0.7.2] - 2021-03-16
### Added
- [PR#23](https://github.com/EmbarkStudios/cfg-expr/pull/23) added a `PartialEq` implementation for `Expression`, primarily for cases where an `Expression` is stored in a type that itself requires `PartialEq`. This is only a simple syntactical equality check. Thanks [@gdesmott](https://github.com/gdesmott)!

## [0.7.1] - 2021-02-17
### Fixed
- Fixed support for the `uclibceabi` environment added for one target in rust 1.50.0.

## [0.7.0] - 2021-02-12
### Changed
- Updated the builtin target list to Rust 1.50.0. Again, somewhat of a breaking change as many targets were removed or changed.

### Fixed
- Update smallvec to fix an [advisory](https://rustsec.org/advisories/RUSTSEC-2021-0003)

## [0.6.0] - 2021-01-04
### Changed
- Updated the builtin target list to Rust 1.49.0, this is somewhat of a breaking change, as rustc now considers all `android` targets to have the `gnu` environment, where previously, it was unspecified.

## [0.5.1] - 2020-12-15
### Changed
- Updated the builtin target list to Rust 1.48.0

## [0.5.0] - 2020-10-20
### Changed
- Updated the builtin target list to Rust 1.47.0

## [0.4.1] - 2020-06-04
### Fixed
- Removed `dbg!` prints accidentally left in.

## [0.4.0] - 2020-06-04
### Added
- [PR#9](https://github.com/EmbarkStudios/cfg-expr/pull/9) added the optional `targets` feature, which allows matching the various `target_` predicates against a [`target_lexicon::Triple`](https://docs.rs/target-lexicon/0.11.0/target_lexicon/struct.Triple.html).

### Changed
- [PR#9](https://github.com/EmbarkStudios/cfg-expr/pull/9) changed the `Arch`, `Vendor`, `Os`, and `Env` types to no be longer enums, and are instead thin wrappers around strings. This allows for custom targets where one or more components of the target triple are not built-in to rustc. Resolved [#8](https://github.com/EmbarkStudios/cfg-expr/issues/8).
- Changed `ParseError` to remove the lifetime and just keep an owned string of the expression that failed to parse.
- Updated the list of built-in rustc targets to 1.43.1.

## [0.3.0] - 2020-04-05
### Changed
- [PR#7](https://github.com/EmbarkStudios/cfg-expr/pull/7) changed `Expression::eval` to take a `Logic` trait, to enable evaluation of 'unknown' predicates. Thanks [@sunshowers](https://github.com/sunshowers)!

## [0.2.1] - 2020-03-30
### Fixed
- [PR#6](https://github.com/EmbarkStudios/cfg-expr/pull/6) fixed nested predicate evalution. Thanks [@sunshowers](https://github.com/sunshowers)!

## [0.2.0] - 2020-02-05
### Added
- Added `targets::rustc_version` which can be used to retrieve the version string of the the rustc used to generate the list of targets.

### Changed
- `targets::ALL` now uses the built-in targets for rustc 1.41.0

## [0.1.0] - 2020-01-09
### Added
- Initial add of all the things
