The complete change history is available in the GitHub repo: https://github.com/openjdk/guide/commits/master

You can also see history for individual files: https://github.com/openjdk/guide/commits/master/src/changePlanning.md

Adding the date was suggested in a previous thread. To me it serves as a way to at least get an impression of how current some information is. In this case it also serves as a tag on the document to refer to in discussions where the version number was previously used. Since the date is kept up to date automatically it's a more convenient way to tag the document.
