Note this does not support 1D textures, volume textures, cubemaps, or texture arrays. DDSTextureLoader is recommended for fully "precooked" textures for maximum performance and image quality, but this loader can be useful for creating simple 2D texture from standard image files at runtime.

 ## Release Notes
 
-* The alpha mode specification for DDS files was updated between the March 2013 and April 2013 releases. Any DDS files created using the ``DDS_FLAGS_FORCE_DX10_EXT_MISC2`` flag or the texconv ``-dx10`` switch using the March 2013 release should be refreshed.

 * Due to the underlying Windows BMP WIC codec, alpha channels are not supported for 16bpp or 32bpp BMP pixel format files. The Windows 8.x and Windows 10 version of the Windows BMP WIC codec does support 32bpp pixel formats with alpha when using the ``BITMAPV5HEADER`` file header. Note the updated WIC is available on Windows 7 SP1 with [KB 2670838](https://walbourn.github.io/directx-11-1-and-windows-7-update/) installed.
 
 * While DXGI 1.0 and DXGI 1.1 include 5:6:5 (``DXGI_FORMAT_B5G6R5_UNORM``) and 5:5:5:1 (``DXGI_FORMAT_B5G5R5A1_UNORM``) pixel format enumerations, the DirectX 10.x and 11.0 Runtimes do not support these formats for use with Direct3D. The DirectX 11.1 runtime, DXGI 1.2, and the WDDM 1.2 driver model fully support 16bpp formats (5:6:5, 5:5:5:1, and 4:4:4:4).
 
-* WICTextureLoader cannot load .TGA or .HDR files unless the system has a 3rd party WIC codec installed. You must use the DirectXTex library for TGA/HDR file format support without relying on an add-on WIC codec.
