I'd really like to merge this PR, however I would need some documentation for this similar to what is here: https://github.com/joomla-framework/database/blob/3.x-dev/docs/v1-to-v2-update.md
Can you please add a file with a few lines to describe this? Thank you!

Can you also check if you got everything from #311 covered in your PR as well? Then I would close the other PR.
