That’s right. The free office suite LibreOffice is designed to be compatible with documents saved by Microsoft Word. One of the most common features of Microsoft Word (other than the basic word–processing functions) used in business is called Track Changes.
The Track Changes function is used when multiple people have input — at least temporary editing rights — to a Word document.
This might occur when members of a team are working on documentation. Another example would be preparing a letter or other document for approval and issue by a second party, e.g. drafting a letter for the boss.
Track Changes allows the document itself to track deletions, additions, formatting changes, and other such changes to the document.
In my own experience in the corporate world, we used Track Changes during internal contract reviews. Various functional groups would edit their appropriate portions of a document and submit them to the lawyers who handled the final consolidation of the comments and edits.
One trap with Track Changes is that it keeps all the changes in history, even if they were approved or cancelled. Although you can display the net effect of the document changes, hiding the changes themselves, you really don’t want to do that when you are negotiating changes.
Always make the final edits in a virgin, untouched copy of the document. Otherwise, the "other side" could Show Markup (Show Changes) and see the alternative edits and comments that you really wouldn’t want to share during negotiations.
Microsoft Word is the dominant word processor in the business world. However, LibreOffice is an upcoming, free, open-source office suite that includes its own word processor.
LibreOffice Writer was designed for word processing. It was also designed to be compatible with other common word processors, and able to read and write their files.
In my testing, LibreOffice 5.2.2 includes compatibility with most (I didn’t test all) functions of Microsoft Word 2013, including the Track Changes function.
At this point, I think that Microsoft Office 2013 is the final version that I am likely to purchase. LibreOffice seems to be a much more cost-effective solution for me.
