-We are going to experiment with our development process, getting away

-validation stages. At any particular time we might have anywhere from
-1 to 6 projects in flight each of which continuously pulls from master,
-but does not push back to master until the code is ready to be
-deployed to production. The point at which a project is ready to be
-deployed then takes roughly the place of the QA phase of our old cycle
-mode. At this time, we will do a PR, and go through a series of

-The main goal with this change is to reduce the latency from feature

-throughput by making more efficient use of QA time and reducing idle
-cycles. We expect people to participate in more than one project

-settings and speed work, which are in branches of prod. We will merge
-these back to prod and then master this week. We have 3 other projects
-that are in master, the excel API, the server side SDK and the MIC
-administration and enforcement components. These we hope to stabilize
-as soon as possible so that we can merge them to prod and deploy them
-along with the rest. Once we have all this, prod and master should be
