Ghostscript/GhostPDL 9.56.1

on GitHub

Important: This release includes the new PDF interpreter (implemented in C rather than PostScript). It is both integrated into Ghostscript (now ENABLED by default), and available as a standalone, PDF only, binary. See https://ghostscript.com/pdfi.html for more details.
This also bundles the latest zlib (1.2.12) which addresses a security issue (CVE-2018-25032)
