Buildah version 1.18.0 Release Announcement

We’re pleased to announce the release of Buildah version 1.18.0 which is now available from GitHub for any Linux distro. We are shipping this release on Fedora 32 & 33 and RHEL 8.4. This will also be shipped on CentOS, openSUSE and Ubuntu in the near future. In addition, container images will be available at https://quay.io/repository/buildah/stable and https://quay.io/repository/containers/buildah.

The Buildah project has continued to grow over the past several weeks, welcoming several new contributors to the mix. This release features the notable enhancements: Short name aliases for container image names can now be declared and used more securely, the pull policy to use with the buildah pull command can now be specified, a few speed improvements to the build process were created, and a number of bug fixes.

• Short name aliases can now be declared and used in a more secure manner. For more details see this blog post.
• The --policy option has been added to buildah pull allowing the user to specify the pull policy to use when pulling. The valid values are: missing, always and never. See (buildah-pull(1)](https://github.com/containers/buildah/blob/main/docs/buildah-pull.md) for details.

This release comprises changes made for v1.17.0 through v1.18.0.
