Release Notes: Apart from many bugfixes, such as fixing a multithreading problem introduced in iText 5.3.5, this release focuses on the creation of structured PDFs. It's now possible to create PDFs that are automatically tagged when using iText's high-level objects such as Document, Paragraph, PdfPTable, etc. Tagged PDF is a first step towards better support for PDF/UA and PDF/A (level A) compliance.
Release Notes: This version solves a major bug introduced in iText 2.1.5: some tagged PDF examples were broken, and in specific cases form fields weren't filled out. The code causing these bugs has been removed. Many smaller bugs have been fixed. There's also some new functionality: PdfPTable finally supports rowspan. Timestamping and OCSP are now possible with iText. There are several new methods, for instance: to skip the last footer in a PdfPTable, to set the initial leading (which is zero by default), and so on.
Release Notes: Internal changes were made to increase the readability of the code as well as the memory and CPU usage of the library. Most of the bugs reported in the last three months have been fixed. New functionality includes support for the JBIG2 format, support for actions in FdfWriter, support for the HR tag in HTMLWorker, and a method to add blank pages in PdfCopy.
Release Notes: Apart from support for JPEG2000 (both jp2 and j2k) and support for base64-encoded images in XFA forms, this release doesn't bring any new functionality. However, it fixes some bugs that were introduced in 2.0.5. The most important issue that was solved is the broken RTF functionality. Problems with PdfNameTree, PdfReader/PdfStamper, WMF images, and others were fixed.
Release Notes: You can now define a repeating footer for a PdfPTable. Lists and combo fields can now be set in the AcroFields object. There was some serious debugging activity in the area of class Table. The toolbox looks a little bit different now. There's a new tool that allows you to inspect the internals of a PDF file. In the area of RTF generation, some minor bugfixes were done.
