IText 5.3.5、導入マルチ スレッドの問題を解決するなど、多くのバグ修正から離れてこのリリース構造化 Pdf の作成に焦点を当てます。IText の文書、段落、PdfPTable などの高度なオブジェクトを使用する自動的にタグ付けされた Pdf を作成することが可能になりました。タグ付き PDF は、PDF/UA と PDF/A (レベル A) コンプライアンスのサポートが改善への第一歩です。

Major feature enhancements, Major bugfixes
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.
このリリースの大きな一部 pdf ファイルを解析します。それは特別なエンコーディングと外国の言語のサポートを追加します。解析エラーを修正し、無効な PDF 構文を読み取るときの iText より寛大に。さらに、iText 2 GB より大きい Pdf を生成できるようになりました。このリリースの PAdES の実装については、java.awt iText グーグル人造人間とゲームの使用を容易にするために依存関係を削減、いくつかのギャップを塗りつぶします。

major release
A large part of this release involves PDF parsing. It adds support for special encodings and foreign languages. It fixes parsing errors and makes iText more tolerant when reading invalid PDF syntax. Furthermore, iText is now able to generate PDFs larger than 2 GB. This release fills some gaps regarding the implementation of PAdES, and reduced the dependency on java.awt to ease the use of iText on Google Android and GAE.
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.
Functionality was added that allows you to completely remove an optional content layer (OCG). This is mainly a maintenance release that fixes all bugs reported on the mailing list since June 6.
Some functionality that was needed in XML Worker 1.0.0 was introduced. For instance, high level interfaces (Indentable, Spaceable) and a WritableDirectElement class were introduced. The logging that was introduced in 5.1.0 was changed so that it works the same way other logging frameworks do. A simple System.out logger, SysoLogger, is now provided. Some bugs were fixed to solve PDF reading and parsing problems, to solve problems with list symbols, and to avoid ClassCastExceptions when reading/manipulating existing OCG layers.
