+  Python
+  * Removed Python 2.x support.
+  * Pure python descriptor_pool.AddSerializedFile() will always build the
+    file and return FileDescriptor which is same with python c++ extension
+  * type errors thrown by MergeFrom now report fully qualified class names
+  * Protobuf python generated code are simplified. Some platforms that uses
+    "is"("is not") to compare the enum or descriptor's label/type may fail,
+    should use "=="("!=") instead.
+
+  C++
+  * Generated code now uses the c++11 standard integer types int{32,64}_t and
+    uint{32,64}_t
+  * Reduce memory usage of the DescriptorPool type.
+  * Moved the zero-argument New() method on messages to the base class (internal
+    optimization).
+  * Unused return values marked with `PROTOBUF_MUST_USE_RESULT` are now
+    correctly attributed.
+  * Demotes PrintPath log for maps in MessageDifferencer down from WARNING to
+    INFO.
+  * Make sure FullMessageName() is always private.
+  * Fix race condition in EnumDescriptor.
+  * Remove MessageLite::GetMaybeArenaPointer.
