## [3.3.0] - 2024-02-28
### Added
- Embedded Linux support
- Apple tvOS support
- Android x86 and x86_64 support

- Crashes and undefined behavior caused by incorrect marshaling when using the IL2CPP scripting.
## [3.2.2] - 2023-11-14

### Changed
- Applied consistent code formatting.
- Updated to WebGL sub-packages from 1.0.0 to 1.0.1.
## [3.2.0] - 2023-09-14
### Changed
- Updated binaries to version 1.1.1.
- Updated WebGL sub-packages to version 1.0.0.
## [3.1.0] - 2023-08-25
### Added
- WebGL native libraries are now installed via sub-packages
- Full Apache 2.0 license text
### Changed

### Changed
- [Breaking] Reduced public API to minimum requirement.
- Added missing XML documentation for remaining public API.
- Updated KTX-Software-Unity to [1.1.0](https://github.com/atteneder/KTX-Software-Unity/releases/tag/v1.1.0)
### Removed
- Utility classes `TextureLoaderBase`, `TextureFileLoader` and `TextureUrlLoader` were moved to KtxUnityDemo project
- `TextureBase.LoadBytesRoutine` (was replaced by `LoadFromBytes` previously)
## [2.2.3] - 2022-11-18
### Fixed
- WebGL build errors (unresolved symbols during linking) due to outdated native library
## [2.2.2] - 2022-09-29
### Changed
- Marked `TextureBase.LoadBytesRoutine` obsolete in favor of `TextureBase.LoadFromBytes`
### Fixed
- Made `TextureBase.LoadBytesRoutine` public again to preserve API compatibility
## [2.2.1] - 2022-09-28
### Added
- Low-level API that gives finer control over the loading process (alternative to `TextureBase.LoadBytesRoutine`)
- `ManagedNativeArray` wrapper for efficient access of managed `byte[]` from C# Jobs
- Basis Universal texture (.basis) Editor import
- Support for loading any single image/layer/mipmap level of textures of any type (arrays, cubemaps, volumes)
- Support for discarding mipmap level chain (and import just one mipmap level)
- Support for importing Basis Universal texture types 2darray, 3d, video, cubemap (single images only at the moment)
- Many property getters on `KtxTexture` (e.g. `needsTranscoding`,`hasAlpha`,`isCubemap`)
- Experimental support for importing uncompressed KTX 2.0 textures (limited set of formats for now; #47)
### Changed
- De-prioritized texture formats `RGBA4444` and `BGR565` to avoid incorrect channel usage or low quality. Transcoding to `RGBA32` instead.
- Bumped minimum required Unity version to 2019.4 LTS
### Fixed
- Textures with alpha channel are shown blended (with checkerboard background) in the inspector now (`alphaIsTransparency` is enabled; #64)
- Avoid extra memcopy of input data by using `ManagedNativeArray` in `LoadFromStreamingAssets` and `LoadFromUrl`
- Improved texture format usage detection (linear vs. sRGB sampling)
- Loading of native library on Linux (thanks [@Blackclaws][Blackclaws] for #60)
## [2.1.2] - 2022-04-14
### Fixed
- Fix undefined variable error when building project

- Editor Import via `ScriptableImporter` (thanks @hybridherbst][hybridherbst] for #45)

### Changed

### Fixed
- Will not transcode textures with sizes that are not a multiple of four to incompatible DXT5 or BC7 formats anymore
- Re-compiled macOS native library in release mode (`MinSizeRel`; was `Debug`). Expect improved performance.
