* Can now extract files from .afa version 3 archives
* Can now extract files from .flat files
* Includes recursively extracting .flat files contained in other
archive formats
* Added option to extract images only
* Now converts images to PNG format by default
* WebP format also supported
Because the table of contents is encrypted in .afa version 3 archives,
the support is a bit limited. Only known file types can be extracted and
they do not retain their original filenames (they are given numbered
filenames instead).
