- Added more checks on the integrity of screen's configurations ("config.txt") and remove implicit order dependencies;
- Added new API to allow users to retrieve variants of their LE licenses.
V3.0.0 – February 2021
- A new licensing policy was implemented. Unless you are using LDK licensing, you will require a new license string. Please contact your technical representative if you did not receive one.

ScreenPro Version 2.0 introduces the following new features and functionality:
- PrintFlat functionality now available for Mirror/Pearl.
- Cross Web Calibration to correct for banding or density non-uniformity
- Web calibrations can now be applied to Screen sets.
- Performance improvements
- For Mirror/Pearl in ScreenPro Core Technology.
- For Chameleon Screens in the ScreenPro application
- Licensing option to be able to screen with up to 16 instances in the ScreenPro application.
- Quality Improvements
- 16 Bits Per Pixel (bpp) input support in Desktop and Command line application.
- Alphanumerical Colorant names are now supported.
- Mirror/Pearl now supports 256 input channels.
- New PassThrough screening method allows the user to test pre-screened content from the application and the SDK.

- Sample application now includes examples of the IOHandler feature.
- Command line application has been extended with additional arguments:
- Mirror/Pearl configuration file updated to new format: Tom's Obvious, Minimal Language (TOML) to improve readability and extendibility.
V1.8.0 – April 2018
- Extra ink limiting and screen quality improvements for MirrorPearl
- Support for 16 screen levels in MirrorPearl
- 16 bits per pixel input support for ScreenPro DLL

V1.7.0 – December 2017
- The user can now add/remove custom destinations in the Preferences->Output Settings dialog.
- Custom routines can be used when reading screen tile data (potentially allowing diskless operation).
See the ScreenProRegisterIOHandler(…)
- For the Mirror, Pearl and Chameleon screen types it is now possible to optionally specify an X and a Y offset respectively. Both are integer values and default to zero. This is useful when screening a large image in separate bands and screening each band separately, so that the X and Y offsets for each tile correspond to the X and Y position respectively of the top-left hand corner of the tile in the original image.
- The Windows command line application now accepts optional -X and -Y arguments for specifying the X and Y offset values respectively.
- The Linux command line application also accepts -X and -Y arguments.
- The maximum number of colorants is now limited to 16.
- Processing TIFF and PDF files concurrently would occasionally fail due to file locking issues.
(This solution has necessitated a reduction in logged clrip process output.)
- File names containing tilde characters would be written into JDF output files incorrectly.
- In some circumstances color strategies with a space in their name might not be found if referenced from a JDF.
V1.6.0 – November 2017
