iText is a library that contains classes to generate and manipulate documents in the Portable Document Format (PDF). Document manipulation includes splitting, merging, and filling out forms (AcroForms, static and dynamic XFA forms).

Changes

This release brings the long-awaited support for PAdES-LTV (this will be part of the upcoming PDF-2 standard), improves the code for parsing PDFs for images, fixes most of the bugs which were reported since the previous release, and makes iText more tolerant towards PDFs which weren't created correctly.
