CppInterOp version 1.4.0

Introduction

This document contains the release notes for the language interoperability library CppInterOp, release 1.4.0. CppInterOp is built on top of Clang and LLVM compiler infrastructure. Here we describe the status of CppInterOp 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.

CppInterOp exposes API from Clang and LLVM in a backward compatibe way. The API support downstream tools that utilize interactive C++ by using the compiler as a service. That is, embed Clang and LLVM as a libraries in their codebases. The API are designed to be minimalistic and aid non-trivial tasks such as language interoperability on the fly. In such scenarios CppInterOp can be used to provide the necessary introspection information to the other side helping the language cross talk.
