How to update LibreOffice on OS X

Hi, I have a question regarding the update of LibreOffice. How can I update LibreOffice on OS X 10.10 Yosemite?
Should I uninstall currently installed version and then install the latest one? Or can I install over the existing installation without the uninstallation? Thanks.
