 * The am33 port, which had not worked for several years, has been removed
   from ports.
+
+* The _BSD_SOURCE and _SVID_SOURCE feature test macros are no longer
+  supported; they now act the same as _DEFAULT_SOURCE (but generate a
+  warning).  Except for cases where _BSD_SOURCE enabled BSD interfaces that
+  conflicted with POSIX (support for which was removed in 2.19), the
+  interfaces those macros enabled remain available when compiling with
+  _GNU_SOURCE defined, with _DEFAULT_SOURCE defined, or without any feature
+  test macros defined.
