+ o Removed features (directory authorities):
+
+ - Directory authorities no longer advertise or support consensus
+ methods 1 through 12 inclusive. These consensus methods were
+ obsolete and/or insecure: maintaining the ability to support them
+ served no good purpose. Implements part of proposal 215;
+ closes ticket 10163.
+
+ o Minor features (directory authorities)
+ - If a directory authority can't find a best consensus method in the
+ votes that it holds, it now falls back to its favorite consensus
+ method. Previously, it fell back to method 1. Neither of these is
+ likely to get enough signatures, but "fall back to favorite"
+ doesn't require us to maintain support an obsolete consensus
+ method. Implements another part of proposal 215.
