Good question. Fleming Maxwell etc. are large milestones. We have internally focused on project planning in the last few weeks, for many reasons, this is one of them. I have posted internally the following message which was well received (it was part (addendum) of a larger message, thanking the team for their work in the last 2-3 weeks.
"Just add, for clarity. we are not en route to Fleming as a target. We are en-route to launch!. Fleming like all deliverables will fall out of the project plan. So please think we are en-route to launch and we will all be guided by the project in terms of Fleming/Maxwell/Beta and many other deliverables.`
In short, we will deliver many more components than just Fleming, Maxwell, Beta etc. and will get these from effective project planning. Think of these named releases as significant releases we will market like crazy.
@Nadia there is spearheading management of that and so far is transforming the team’s focus, moral and visibility of upcoming work. So yes Fleming will come before Maxwel, but will be much more clear from the plan and each of these releases will have utility (i.e. you will be able to do stuff with them 
) Fleming will be slightly more than a routing node from home that has almost no utility. It will have some utility and the plan will tell us what we can give you, the community, in terms of nodes from home with utility.
To be clear, I am pushing very hard and the teams are working at a pace (and most of them happier) than I have not seen for a while, in providing that utility. The big issue for us is that I am not wishing to have Fleming as less than alpha 2, but more. In saying that we will be clear what all that means and test it is possible right now. I think this weeks dev update will allow you to see all of this more clearly (as we will) as we release the Gantt representation of all the work, tasks and critical path to launch. Fleming etc. will all become much clear that way.
