0.7 beta 20/02/2018
- Drag webpack kicking and screaming into the current decade and put up on github for others to play with
- Add support for OptiPNG which seems to work better than pngcrush, so OptiPNG is the default if both are installed
- Remove support for htmlcrunch as it's no longer maintained (website doesn't exist)
- Don't strip JPG files of additional metadata to preserve EXIF tags etc.
