+** 'eql', 'make-hash-table', etc. now treat NaNs consistently.
+Formerly, some of these functions ignored signs and significands of
+NaNs.  Now, all these functions treat NaN signs and significands as
+significant.  For example, (eql 0.0e+NaN -0.0e+NaN) now returns t
+because the two NaNs have different signs; formerly it returned nil.

 ** The function 'make-string' accepts an additional optional argument.
 If the optional third argument is non-nil, 'make-string' will produce
 a multibyte string even if its second argument is an ASCII character.
