However, versions upto 4.2.0 were licensed under the business-friendly LGPL.  From 2.1.7 the version jumped to the 4 series, one of the main changes was a renaming of the packages.  These two versions are available in several repositories on github, see for example: [iText 4.2.0](https://github.com/ymasory/iText-4.2.0) and [iText 2.1.7](https://github.com/hwinkler/itext2).  The jars can be downloaded from [Maven Central.](https://mvnrepository.com/artifact/com.lowagie/itext/2.1.7). iText 2.1.7 and iText 4.2.0 are available under a ![business friendly license](https://github.com/Vedenin/useful-java-links/blob/master/img/business-friendly.png?raw=true). The book iText in Action 2nd Edition, from Manning, was written around the time of these LGPL versions.  If you are making any contributions to iText please make them to these LGPL repositories on GitHub.
