This graph is a history of commits and state changes to /trunk/phase3 between r47450 and r92475 since June 1, 2009 and before July 18, 2011. (Prior commits and state changes were subject to mass operations that obfuscated the data). Not included: checkins that span /trunk/phase3 and some other directory.
The "newly new" psuedo-state is a plot of new revisions added in a given week. The "reviewed" psuedo-state is all revisions that transition from "new" to some other state in a given week.
