As described in http://stackoverflow.com/questions/38571244/which-output-format-of-libre-office-can-i-use-to-track-the-history-of-my-files I generated a simple FODT file.
When I change
Hello World. to
Hello World!, meta-data and the text itself changes. Additionally wsome strange config items change on every save what is there meaning?
It would be also nice to find a way to avoid the change on every save: How to avoid .fodt file attributes changing on every save?
