+* BREAKING CHANGE: Internal signature changes to ChangesListSpecialPage
+ and subclasses. It should only break if you call buildMainQueryConds
+ (changed to buildQuery with new signature) or doMainQuery (new
+ signature). Subclasses are likely to call at least doMainQuery
+ (possibly both), but other classes might too, because they were
+ public.
+
+ Also, some related hooks were deprecated, but this is not yet a
+ breaking change.
