Hello,
After upgrading to the newest version 10.1.0 we found two features lost:
1) Background elements (elements of page header/footer located in page body) cannot be rendered to PDF and completely break the output document. See Test11.
2) Embedded fonts are not rendered to PDF. See Test12.
Please pay attention that both version work properly in Aspose.Words v. 4
Also you can see that watermark properties significantly changed while converting to PDF.
Best regards, Evgeniy
