to bring PDF4NET up to date to latest technologies. This new release brings support for all .NET platforms,
a fully rewritten internal architecture making it more testable and several new features that we could not
support with the old version.
All these updates brought several breaking changes in the public API when compared to PDF4NET v5 but we're
fully supporting the customers that wish the make the transition to the new PDF4NET.
