Harlequin Core v13.2r3 Release Notes


Harlequin Release Notes are now published directly to our website.

Harlequin Core v13.2r3 is a minor release since v13.2r2. This release consolidates the work of v13.2r0, 13.2r1, and 13.2r2.

Where performance enhancements indicate % values or time improvements, they are sometimes specific to job types and configuration; they are not cumulative.

Alerts and guidance

This release is for Harlequin Core SDK only; Harlequin MultiRIP (HMR) was not provided.

HQN-385112 - We have deprecated OptimizedPDFCompactMemory for 13.2r3, and will be removing it in 14.0.

Now functions as documented: 

Fix crash when running customers performance test suite file

Integrate ZLib-ng into Harlequin Core for all platforms.

Improved performance of decompression.

Affects performance: This has a variable effect on performance, for example jobs that achieve a lot of re-use using HVD benefit less from this because images are often only decompressed once. Jobs with one large image at high resolution that were highly compressible benefit more, up to 200% of the decompression operation the RIP must perform.

HVD: Performance: limited implementation of - avoid unnecessary compositing for 100% pure black objects

Improve slow reading of very large xref Tables with a large number of sections

Minor performance improvement for files resaved by the MAKO library


Add Zlib-ng license & copyright to all relevant documents

updated the relevant areas of documentation

Fix slowdown due to image store caching memory build up

optimize when encountering rectfill with extra trailing moveto
