The latest FileOpen Client for Adobe Acrobat/Reader on Macintosh, Build998, has been released and can be installed from https://plugin.fileopen.com
This build incorporates a new print dialog and augments the data sent to the PermissionServer in the client/server print-control interaction.
It also includes changes to enable operation in Protected Mode, which is currently in preview for Acrobat/Reader.
Installation of the new Client does not require uninstall of the previous version.
