Buildah version 1.42.0 Release Announcement

We’re pleased to announce the release of Buildah version 1.42.0, which is now available from GitHub for any Linux distro. We are shipping this release on Fedora 42 and Fedora 43. Buildah will also be shipped on CentOS, OpenSUSE, and Ubuntu soon. 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 notable changes:

• The meaning of --pull now emulates Docker’s --pull=always
• Destination locations for several commands that now end with a /. are treated as directories.
• The --imagestore option can now be used when configuring storage.
• The --transient-store option stores metadata about containers under the storage state directory. See the buildah (1) man page for details.

This release comprises changes made for v1.42.0 and will be included in Podman v5.7.
