"We are issuing this interim public draft as it sets out a number of changes made in response to comments received on the Last Call draft. Items under consideration for change for Candidate Recommendation include the name of the font-height-override-before and font-height-override-after properties. "
Most of the draft is cleaned up, but there are some new and re-organized sections. Block areas and Inline areas have been restructured and expanded, while "Properties for Links" has become Properties for Dynamic Effects Formatting Objects and now includes sections which used to follow it.
