Introduction

This document contains the release notes for the automatic differentiation plugin for clang Clad, release 0.9. Clad is built on top of Clang and LLVM compiler infrastructure. Here we describe the status of Clad 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, this document applies to the next release, not the current one.
