+1 Thanks Mihai for preparing the report. One minor detail: I noticed that some of the "traditional metrics" that we normally include in the report (number of non-committer commits per month, number of active reviewers per month) are missing; I think it'd be nice to include them in the final version of the report, to keep logging the trend around these figures.
