Version 7.3

Release 0

Read more about changes you may need to make.

  • Shell protection - added extra anti-debugging technologies.
  • Shell protection - improved runtime decryption of Shell-protected code.

Version 7.2

Release 0

  • DinkeyAdd and DinkeyRemote - these tools are now split into 3 parts: GUI front end, command-line front end and back-end library.
  • DinkeyAdd and DinkeyRemote - command-line programs and libraries now available for macOS and Linux.
