@@ -4,6 +4,8 @@ changes in sbcl-1.0.16 relative to 1.0.15:
     NIL whenever we can't get a truename, as was the case before 1.0.14.
   * minor incompatible change: SB-BSD-SOCKETS:NAME-SERVICE-ERROR now
     inherits from ERROR instead of just CONDITION.
+  * new feature: SB-INTROSPECT can provide source locations for instances
+    as well. (thanks to Tobian Ritterweiler)
   * optimization: binding special variables now generates smaller code
     on threaded platforms.
   * optimization: MEMBER and ASSOC are over 50% faster for :TEST #'EQ
