Oct 1, 2025

October 2025: ScrollPrize/villa delivered critical bug fix and performance enhancements for rendering and inference pipelines. Addressed a rendering failure by removing an invalid 'unit' field in multiscale render configuration; added TIFF support and memory-mapped image loading to enable processing larger/high-resolution images. These changes improve stability, throughput, and scalability for high-resolution datasets, delivering business value by reducing preprocessing time and avoiding rendering outages.
