with ITK 3.20, this release is compatible with ITK v4.2.0 and more recent releases. We are still actively developing RTK with both new filtered backprojection and iterative algorithms so I still encourage the use of git to be up-to-date. As usual, please report
any issue that you encounter with RTK, we are happy to help when we can. Note the l<a href="http://www.openrtk.org/RTK/project/publications.php" target="_blank" moz-do-not-send="true">ist of publications using RTK</a> on the main site: please send me the DOI
