-NVIDIA Texture Tools version 2.0.5
- * Fix error in single color compressor. Fixes issue 66.
- * Detect mismatch between CUDA runtime and driver, and disable CUDA in that case.
- * Fix cmake files when compiling NVTT as a shared library.
- * When linking nvtt dynamically on unix, link all libraries dynamically.
- * Select fastest CUDA device.
-
 NVIDIA Texture Tools version 2.0.4
  * Fix error in RGB format output; reported by jonsoh. See issue 49.
  * Added support RGB format dithering by jonsoh. Fixes issue 50 and 51.
