+# Changes to Clojure in Version 1.8
+
+## 1 New and Improved Features
+
+### 1.1 Direct Linking
+
+*This feature is a work in progress, subject to change.*
+
+Direct linking can be enabled with -Dclojure.compiler.direct-linking=true
+
+Direct linking allows functions compiled with direct linking on to make direct
+static method calls to most other functions, instead of going through the var
+and the Fn object. This can enable further optimization by the jit, at a cost
+in dynamism. In particular, directly-linked calls will not see redefinitions.
+
+As of 1.8.0-alpha3, clojure.core is compiled with direct linking by default
+and therefore other namespaces cannot redefine core fns and have those
+redefinitions seen by core code.
+
+Functions declared as dynamic will never be direct linked.
+
