Comment(by pramsey):

 Using this simple case to compare 2.0 and 2.1, and 2.0 is stably correct
 and 2.1 is variably correct and incorrect.
 {{{
 SELECT t1.gid As t1_gid, t2.gid As t2_gid
  , ST_DWithin(t1.geog, t2.geog,100)
  , ST_Distance(t1.geog, t2.geog) As dist
 FROM test_geogs As t1 CROSS JOIN test_geogs As t2;
 }}}
