Hello Linux Geeksters. As you may know, LibreOffice is an open-source popular Office Suite application, running on Linux, Windows and Mac OS X. The latest version available is LibreOffice 4.1.4, which has been recently released. For a list of changes and enhancements, see the official release notes.
