LibreOffice vs OpenOffice
LibreOffice is the successor to OpenOffice.org, commonly known as OpenOffice, which had its last major update in 2014. (There have been occasional minor updates since then, but OpenOffice has a history of leaving security issues unfixed so all users are strongly recommended to upgrade to LibreOffice, which is more actively maintained.)
LibreOffice adds many extra features and improved Microsoft Office compatibility, and has regular releases with security updates. Learn more about the history of OpenOffice and LibreOffice here, and check out this comparison:
