Introduction

This document contains the release notes for the interactive C++ interpreter
Cling, release 0.4. Cling is built on top of Clang and
LLVM compiler infrastructure. Here we
describe the status of Cling in some detail, including major
improvements from the previous release and new feature work.

Note that if you are reading this file from a git checkout or the main
Cling web page,
this document applies to the next release, not the current one.
