Harlequin Core 13.2r0 Release Notes

This page applies to Harlequin v13.2r0 and later; both Harlequin Core and Harlequin MultiRIP.


Harlequin Release Notes are now published directly to our website.

Harlequin v13.2r0 is the second major release since HQN v13.0r0. This release consolidates work of HQN v13.0r0 and v13.1r0. We also responded to many customer issues including compatibility and other issues that required Core changes, as you can see in the "Harlequin Core v13.2r0 change details" table (below).

Nonetheless there was time for some new developments. Harlequin v13.2r0 introduces:

  • A change to the HMR user interface to help operators manage very long separation names.
  • Updating LDK components for Windows 11 support.
  • HVD optimizations to help identify reusable objects in jobs that are not constructed particularly well.
  • Improvements to RIP farm.

Alerts and guidance

  • A new version of the HMR plugin kit 20.3r3 is also now available to accompany Harlequin v13.2r0.
  • The updated LDK components v8.3 for Windows 11 support will be installed. LDK components identify as v8.31 on Windows 11, macOS, and Red Hat.
  • The drop-dead date for HMR v13.2 watermark RIPs has been set to July 1, 2023.

Windows 11 support guidance

While Global Graphics have been testing Windows 11 with Harlequin Core SDK and MultiRIP v13.2r0, we have found no platform specific issues; however, the number of machines for automated and performance testing for this platform is currently limited but expanding.

Microsoft officially released Windows 11 on October 4, 2021; support for LDK licensing was scheduled to be introduced after that. We are aware that many customers have upgraded to Windows 11 (or sometimes found it difficult to avoid upgrading); therefore we are announcing support for this platform from 13.2 onwards subject to the following guidance:

  • Upgrading from Windows 10 was phased in by Microsoft and some PCs shipped with earlier version, thus you should ensure that you are using 21H2 build 22000 or later.
  • That your hardware met the minimum requirements for Windows 11 (as defined by the Microsoft downloadable benchmarking application being successfully run).
  • Should you find an issue, where possible please repeat the steps to reproduce it on Windows 10.

Windows 2022 Server note

Global Graphics is not yet ready to sign off Harlequin Core as being formally supported under Windows 2022 Server. This will be completed for v13.xrx available in 2022. Also note that the Server version 2022 is based on Windows 10 and succeeds Windows Server 2019. 

Red Hat Linux

Global Graphics is moving from Red Hat Linux 6+7 to 7+8.x during 2022. Customers have been asking to leverage various features of Red Hat 8.5 and the yet unreleased Red Hat 8.6. We intend to support Red Hat 7 and Red Hat 8 for Harlequin 14, as Red Hat 6 is now in “extended support”.

Known issues

  • Mac ARM compilation is as yet unsupported, though the Makefile implies that it's an option.
  • Recent installs of MSVS2019 do not include the Windows 8.1 SDK. OEMs wishing to build for this OS can retrofit it. See "Updates to supported platforms and compilers" (below).
  • Harlequin Core SDK Installer can fail on Red Hat Enterprise Linux (RHEL) Server 8.1. Global Graphics opened a case (02603280) with Red Hat and are looking for workarounds for support of Red Hat 8.x.
  • In testing Ubuntu 20.4, LE-secured v13.2r0 customizations install OK; however, at the end, the installer says it was unable to run the LDK tool but it created the files on disk. It shouldn't - and doesn't - create an LDK folder. This would be ignored as a workaround.
  • HQN-384531 - Bad output (that is, missing objects) may occur with HVD for some jobs; there may also be a loss of reuse.  This problem was originally reported for HVD with PDF/VT-2 jobs.  However it can happen for other jobs with an XRef object or an XObject with GGSL_Opaque tag (when we have /OptimizedPDFTestOpaqueHint false).  We do not expect this to occur with the combination of /OptimizedPDFPositionIndependent true, and /OptimizedPDFIgnorePatternPhase true.
