+* Update Dart analyzer version to 0.40+ and update minimum Dart version

+  declared in a file from ever being documented, similar to using `@nodoc`
+  (#2369, #2368, #2266, #2355)
+* Some template interface refactors preparing for mustache changes to drop
+  use of dart:mirrors. (#2371, #2370)
+* Add an feature to allow declaring a `DartdocOption`'s value to be a glob.

+  no libraries. (#2360, #2327)

+  intermediate private classes (#2358, #2290, #2094, #2354, #1623)
