    Package        : distro-info-data
    Version        : 0.51+deb11u11

    This is a routine update of the distro-info-data database for Debian LTS
    users.

    It updates the EoL date for bookworm and adds Ubuntu 26.10 Stonking Stingray.

    For Debian 11 bullseye, this problem has been fixed in version
    0.51+deb11u11.

    We recommend that you upgrade your distro-info-data packages.

    For the detailed security status of distro-info-data please refer to
