Update CHANGELOG and set version to v0.21.2

macOS AppleClang does not provide OpenMP by default with XCode.
Use LLVM's OpenMP to fix compile errors of mgard with OpenMP (default).

-Build cache signing
--------------------
-
-By default, Spack will add a cryptographic signature to each package pushed to
-a build cache, and verifies the signature when installing from a build cache.
-
-Keys for signing can be managed with the :ref:`spack gpg <cmd-spack-gpg>` command,
-as well as ``spack buildcache keys`` as mentioned above.
-
-You can disable signing when pushing with ``spack buildcache push --unsigned``,
-and disable verification when installing from any build cache with
-``spack install --no-check-signature``.
-
-Alternatively, signing and verification can be enabled or disabled on a per build cache
-basis:
-
-.. code-block:: console
-
-    $ spack mirror add --signed <name> <url>  # enable signing and verification
-    $ spack mirror add --unsigned <name> <url>  # disable signing and verification
-
-    $ spack mirror set --signed <name>  # enable signing and verification for an existing mirror
-    $ spack mirror set --unsigned <name>  # disable signing and verification for an existing mirror
-
-Or you can directly edit the ``mirrors.yaml`` configuration file:
-
-.. code-block:: yaml
-
-    mirrors:
-      <name>:
-        url: <url>
-        signed: false # disable signing and verification

@@ -287,13 +250,87 @@ To significantly speed up Spack in GitHub Actions, binaries can be cached in
 GitHub Packages. This service is an OCI registry that can be linked to a GitHub
 repository.
 
+A typical workflow is to include a ``spack.yaml`` environment in your repository

+
+A GitHub action can then be used to install the packages and push them to the

+The first time this action runs, it will build the packages from source and

+The build cache entries appear in the GitHub Packages section of your repository,
+and contain instructions for pulling and running them with ``docker`` or ``podman``.
