+** O(1) compilation of `case' and related expressions
+
+Guile now optimizes chains of eq? comparisons to constants, resulting in
+O(1) dispatch time, regardless of the length of the chain. This
+optimization is also unlocked in many cases for `match' expressions with
+many similar clauses whose first differentiator are constants.

+* Incompatible changes
+
+** `copy' read-option removed
+
+This read option would include a copy of the source expression in the
+source-properties of each subexpression. This option has always been
+off by default and lost most of its use value with the switch to a
+compiler in Guile 2.0.
