Release date: April 14, 2021

This release of pdfRender brings a lot of performance improvements and few bugfixes that make PDF to image conversion faster and smoother than ever before. BMP and PNG conversion have been significantly improved, and revisions to the processing of Type1 fonts have reduced memory allocation.
