 Treelite Release Notes 
 ======================
 
-## Current
-BREAKING CHANGES
+## 0.30 (03/23/2018)
+**Major re-factoring of the backend code**
+* New code generator, based on Abstract Syntax Trees (AST)
+  * Build AST first
+  * Iteratively transform AST
+  * Finally convert AST into C/JAVA program
+* Improved abstraction and modularity (no more spaghetti code!)
+  * It's now much easier to "edit" tree prediction logic: you'd just need to
+    operate on a tree graph. Re-factoring was a worthwhile investment for
+    future research.
+    For instance, we could create a new node type in AST representing an AVX
+    operation. A group of conditional nodes can be converted into the AVX node
+    with equivalent semantics.
+* Support for Java: see example at
+  https://github.com/hcho3/treelite-java-example
+
+**BREAKING CHANGES**
 * Prediction library generated by previous versions are NOT compatible with
   the current version. You will have to run `export_lib()` or `compile()`
   again.
