Version 7.4

Release 0

Implemented Demo Software Keys: 'virtual dongles' that can be used in place of a physical Dinkey Pro or Dinkey FD device for evaluation copies of your protected software.
Shell protection - Lock Dongle to Computer feature now works correctly for Shell-protected DLLs.
Shell protection - other performance improvements and minor bug fixes.
Improvements to machine ID calculation for Lock Dongle to Computer feature and software keys.
DinkeyAdd - GUI now allows disabling extra anti-debugging and anti-piracy protections added in version 7.3.0. It may be necessary to disable either of these in rare cases.
Linux DinkeyAdd and DinkeyRemote - front-end programs now search more intelligently for back-end libraries.
Runtime - fixed bug with evaluating very complex algorithms with nested composite variables.

Version 7.3

Release 0

Shell protection - added extra anti-debugging technologies.
Shell protection - improved runtime decryption of Shell-protected code.
DinkeyAdd - now supports DAPF files in JSON format as well as the existing binary format. DinkeyAdd API updated to support reading and writing JSON DAPF files. DinkeyAddCmd has a new command-line option for converting DAPF files between JSON and binary formats.
DinkeyRemote - now supports DRPF files in JSON format as well as the existing binary format. DinkeyRemote API updated to support reading and writing JSON DRPF files. DinkeyRemoteCmd has a new command-line option for converting DRPF files between JSON and binary formats.
DinkeyServer for Linux - improvements to auto-detection of DinkeyServer by protected software.
Runtime code - fixed issues with 'lock dongle to computer' feature on Windows 10 and macOS.
.NET Shell protection - improved memory management at runtime.

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.
DinkeyServer - fixed issue under macOS Yosemite and newer where the viewer could crash displaying network users.
Windows GUI programs now resize correctly under different DPI settings.
PDF protection - text search functionality added to protected PDFs.
OS X runtime - fixed leak of Mach ports that could cause problems if checking the dongle frequently.
Runtime protection API - implemented DONT_RETURN_FD_DRIVE API flag.
Runtime protection API - added support for 64-bit Filemaker.
Runtime code - fixed issue with network users and spawning child processes. Previously, if a child process inherited handles from the parent, it could prevent the network user being freed correctly when the parent process terminated.
Shell protection for native DLLs - if the shell starts a network user, the user is now freed when the DLL is unloaded. Previously the user was not freed until the calling process terminated.
DinkeyWeb - superceded by Smartsign, deprecated and removed from the SDK. DinkeyWeb 7.2.0 files are available on request: contact our support team to request these files.

Version 7.1

Release 1

Runtime code - changes to support detection of the flash drive part of a Dinkey FD on macOS El Capitan. Prior to this release all Dinkey FD protection checks on El Capitan would return error 598.
