Good Afternoon,

We are running 9.9.9 due to the licensing bugs in the post 3 versions of the library. So it's been awhile since we upgraded. I am looking at upgrading if there were some library improvements in newer versions. Do you have a place where changes between versions are listed? In my case, I am really interested in any changes in conversion speeds (this version is a bit slow), fixes to random conversion error bugs, and if multithreading bugs have been fixed. The PdfStandardsConverter.ToPdfA1A method slows down insanely slow after just about 100 pdfs. (we convert from pdf to pdfa).
