In the spirit of supporting the community, Baron asked for a table-of-contents blog post that encapsulated all of the recent Oracle 5.6 DMR posts. 
I agree with Baron, a huge amount of information came out today, and this Development Milestone Release (DMR) does have some great features. So below is a list of all of the related blog posts around the 5.6.5-m8 DMR. Hopefully this makes it easier for everyone to find their related information.
