LibreOffice has long since moved on from being an offshoot of the OpenOffice project. It's now the go-to alternative to Microsoft Office, enjoying regular development and a constant tweaking to keep it up to date, stable and secure.
While LibreOffice lacks the bells and whistles of rival freebie Kingsoft Office Suite Free and its Office-inspired ribbon interface, it has the major advantage of offering a full set of office applications, including database, drawing package and mathematical tool on top of the requisite word processor, spreadsheet and presentation tool found in most free office suites.
Scratch behind the slightly dated user interface and you'll find a suite capable of meeting most people's needs, making this zero-cost alternative to Office a valuable tool to have in your armoury. Ever-improving support for third-party file types (including both new and classic Office formats) means you're not cutting yourself off from industry standards while cross-platform support means you can run LibreOffice on Windows, Mac or Linux without having to retrain yourself to a new way of working each time.
