Release iText 7.1.0

We are pleased to announce that iText 7.1.0 is a new release for iText 7 Core and Community, focusing on PDF 2.0 support.

iText 7.1 brings new improvements, and some changes to our compatibility and licensing. The largest change being that the 7.1 release does not preserve full backward compatibility with 7.0. In order to maintain a high quality API and to facilitate future development, some changes and improvements required breaking changes. These are focused in a few areas of iText functionality and thus will only impact a select number of use cases. Read more below on what is affected and improved.

The second largest change is that we are also updating our license key library to 3.0.0 in order to reduce confusion between the separate versions of our license key libraries. pdfSweep, pdfHTML, pdfCalligraph, and pdfInvoice are all bumped up to 2.0.0, to catch any breaking changes in the API of their main dependency iText Core.

What is different in each of these new releases?


  • Backwards compatibility breaks are documented for Java and .NET.
  • Support was added for PDF 2.0 improvements and features, such as AES-256 encryption, Unicode based passwords, the new tagged PDF tag set and namespaces, and associated files. iText 7 already supported industry standards, such as PAdES digital signatures, which have been incorporated in PDF 2.0.
  • The logging mechanism was improved in .NET.

License key library 3.0.0 for Java - for .NET

  • The license key library can now handle iText 5 and iText 7 licenses in parallel.
  • Add-ons are now also registered in PDF metadata.
  • For volume-based commercial licenses, all usage can now be logged.
