Hey all,

We have just wrapped up RC1 and I have a burndown chart [1] of 
blueprints [2] for the Stein cycle to share. I sent a similar email 
after we released Rocky last cycle [3]. I generated data for this chart 
throughout the cycle using a script I have proposed to add to the 
nova-specs repo [4].

Comparing final numbers to Rocky
--------------------------------
Max approved for Rocky: 72
Max approved for Stein: 49
Final completed for Rocky: 59
Final completed for Stein: 29

Our completion percentage of approved blueprints in Rocky was 81.9% and
in Stein it was 59.2%.

We had a significant drop in completion percentage from last cycle. We 
approved many more blueprints than we completed. Comparing the release 
note prelude from Rocky [5] to Stein [6], I think we had an increase in 
larger and more complex user-impacting features implemented this cycle 
than last cycle. Throughout the cycle, we also had the placement 
extraction happening, which was a substantial amount of work not 
represented by a blueprint. Finally, many of the approved blueprints 
which were not completed were also larger and more complex features 
(NUMA-aware live migration, SRIOV live migration, cross-cell resize, 
detach/attach of root volume, just to name a few).

I think we completed an impressive amount of work this cycle and I'm 
proud of how many user-impacting features we released.

Cheers,
