## Recent Changes
### 2.6.3 (March 24, 2019)
- Added image cleaner by @BrianPetkovsek which removes upscaled frames.
- Fixed some PEP8 issues.
- Exceptions in waifu2x are now caught, and script will now stop on waifu2x error instead of keep going on to FFMPEG.
### 2.6.2 (March 19, 2019)
- Removed `--model_dir` verification due to the rapidly evolving number of models added.
