Yes I know. They are only for release notes and also encouraging someone posts that or newer version.
Be ware that processors are the heart of every SoC design and all of the ESL Softwares from Mentor, cadence, synopsys, carbon and etc will be meaningless without them. Processor designing is the most challenging job in Electronic engineering and Today's companies are moving to TLM-2 based models for rapid virtual prototyping. EDA companies' providing Processor designing tools are not really mature for creating every abstract levels and moving from one level to the other should be done manualy though some companies are trying to automate them.
