| Introduction |
| ============ |
| |
| This document contains the release notes for the LLVM Compiler Infrastructure, |
| release {{env.config.release}}. Here we describe the status of LLVM, including |
| major improvements from the previous release, improvements in various subprojects |
| of LLVM, and some of the current users of the code. All LLVM releases may be |
| downloaded from the [LLVM releases web site](https://llvm.org/releases/). |
| |
| For more information about LLVM, including information about the latest |
| release, please check out the [main LLVM web site](https://llvm.org/). If you |
| have questions or comments, the [Discourse forums](https://discourse.llvm.org) |
| is a good place to ask them. |
| |
| Note that if you are reading this file from a Git checkout or the main |
| LLVM web page, this document applies to the *next* release, not the current |
| one. To see the release notes for a specific release, please see the |
