+### v2.15.11 (2016-09-08):
+
+On we go with our monthly release cadence! This week is pretty much all
+dependency updates and some documentation changes, as can be expected by now.
+
+Note that `npm@4` will almost certainly be released next month! It's not final
+what we'll end up doing as far as LTS support goes, but the current thinking is
+that, considering how small and resource-constrained our team is, support for
+`npm@2` will be reduced to essentially maintenance, so we can better focus on
+`npm@3` as the new LTS version (which will go into `node@6`), and `npm@4` as our
+next main development version.
