I think it would be better to rename DD from 27th August 2015 and onward as DD-01 and etc. since that when they started talking about new expansion features.
**in addition to date; would make it easier for readability?
EDIT: 8th October - DD-06 - Culture and Mercenaries

Good suggestion, but rather than number them I've added some headings
