    Package        : distro-info
    Version        : 0.21+deb10u1

    This is a non-security update, enabling distro-info to continue to build
    with the distro-info-data update in DLA-3639-1, which broke some
    test-suite assumptions.

    This update also allows distro-info to support additional columns in
    distro-info-data, easing future updates.

    For Debian 10 buster, this problem has been fixed in version
    0.21+deb10u1.

    We recommend that you upgrade your distro-info packages.

    For the detailed security status of distro-info please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/distro-info
