## [Unreleased] - ReleaseDate
## [0.3.0] - 2020-12-17
## [0.2.0] - 2020-12-14
### Fixed
- [PR#9](https://github.com/EmbarkStudios/spirv-tools-rs/pull/9) Fixed bug in the compiled optimizer that resulted in no output. Thanks [@khyperia](https://github.com/khyperia)!

## [0.1.1] - 2020-11-18
### Added
- [PR#4](https://github.com/EmbarkStudios/spirv-tools-rs/pull/4) added more clear compile errors if neither of the `use-*-tools` features are enabled for either `spirv-tools` or `spirv-tools-sys`.

### Changed
- [PR#4](https://github.com/EmbarkStudios/spirv-tools-rs/pull/4) made `use-compiled-tools` the default feature for `spirv-tools-sys`. This would only affect direct consumers of `spirv-tools-sys`.

## [0.1.0] - 2020-11-13
### Added
- Added initial implementation, which includes the assembler, validator, and most of the optimizer, which meets the current needs of rust-gpu.
