I sent a similar email after Pike was released [1] and these are our 
blueprint burndown chart results for Queens [2].

Comparing to Pike, the trends are similar, with the overall numbers 
down. Things ramp up until the spec freeze, then tail off, with a little 
spike toward the end to get things in by feature freeze.

Comparing final numbers to Pike

Max targeted / approved for Pike: 76 / 69

Max targeted / approved for Queens: 65 / 53

Final completed for Pike: 50

Final completed for Queens: 42


Within targeted/approved/completed, the relative numbers are about the 
same and our percentage of approved / completed is actually better in 
Queens (72% completion percentage of approved blueprints in Pike 
compared to 79% completion percentage of approved blueprints in Queens). 
So while we targeted fewer blueprints in Queens, we did a better job of 
actually completing them. To me, this indicates some level of stability 
with the things we've been working on over the last several releases, 
particularly with respect to cells v2 and placement. It likely also 
means there are just fewer people / organizations trying to contribute, 
which isn't a surprise to me with the maturity of OpenStack. This can be 
both a good thing a bad thing, but I'm not going to try and get into 
that here.

We can talk about this and more during the PTG when we go through our 
Queens retrospective [3].
