new version 2.02 is available: http://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/pdftk-2.02-src.zip
Hey, this would be a great upgrade! 1.4.4 is over three years old ;) Thanks
Because pdftk depends on a gcj-feature which no more supported in Fedora I have retired this package for F20+. So no new version of pdftk will be available on Feodra.
