> 
> 
> This is the Marlin-renderer 0.9.4.3 release providing few bug / enhancement fixes in the MarlinRenderingEngine:
> - Update DPQS to latest OpenJDK 14 patch
> - Improve cubic curve offset computation
> 
> 
> The Marlin-renderer 0.9.4.2 release provides a single long-standing bug fix in the MarlinRenderingEngine: 
> - JDK-8230728, https://bugs.openjdk.java.net/browse/JDK-8230728.

> 
> Special Thanks to Vladimir Yaroslavskiy that provided me up-to-date DPQS 19.05 with many variants, improving almost-sorted datasets. We are collaborating to provide a complete Sort framework (15 algorithms, many various datasets, JMH benchmarks) publicly on github:
