+                    The RTS linker can now unload object code at
+                    runtime (when using the GHC API
+                    <literal>ObjLink</literal> module.) Previously,
+                    GHC would not unload the old object file, causing
+                    a gradual memory leak as more objects were loaded
+                    over time.
