I'd like to use iTextSharp for PDF manipulation. I need it to run under medium trust (webserver) and to be free of charge (sice this is a very small project), therefore there is not much competition.
Unfortunately, since I need it for a commercial project, I cannot use the AGPL introduced with version 5.0. Do you know if I may use the 4.x versions using the LGPL? Or is their license automatically updated to the APGL?
