For many years I have been successfully creating my documents in Writer/Calc using a now old version of OpenOffice.org 3.3.0 on Windows. I would like to update to a latest release version. There are two issues that I have:
1) Should I go with OpenOffice or LibreOffice?
2) If I go with LibreOffice (or even the latest OpenOffice), will I still be able to use my documents without problems?
