<p>This document contains the release notes for the LLVM Compiler Infrastructure,
release 14.0.0. 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 <a class="reference external" href="https://llvm.org/releases/">LLVM releases web site</a>.</p>
<p>For more information about LLVM, including information about the latest
release, please check out the <a class="reference external" href="https://llvm.org/">main LLVM web site</a>. If you
have questions or comments, the <a class="reference external" href="https://lists.llvm.org/mailman/listinfo/llvm-dev">LLVM Developer’s Mailing List</a> is a good place to send
them.</p>
<p>Note that if you are reading this file from a Git checkout or the main
LLVM web page, this document applies to the <em>next</em> release, not the current
one. To see the release notes for a specific release, please see the <a class="reference external" href="https://llvm.org/releases/">releases
