Package: optipng Version: 0.7.5-1 Severity: wishlist As reported at https://blog.codinghorror.com/zopfli-optimization-literally-free-bandwidth/ , Zopfli can produce Deflate-compatible streams appreciably smaller than zlib, at the cost of significantly slower compression time. Please consider adding support for this in optipng, as a new, higher optimization level (e.g. -o8). (A corresponding low-level option should exist to use Zopfli, which -o8 should enable along with the various filter options.)
