    Changes in rpm:

    - split imaevmsign plugin into a multibuild flavor

    Changes in rpm:

    - Add Requires: (rpm-plugin-selinux if selinux-policy)
    - harden ndb code [bsc#1269584] [CVE-2026-44605]
    - split all plugins into subpackages
      * this allows for an easy way to get rid of a plugin, it's also
        what other distributions do
    - make the imaevmsign plugin build in a multibuild flavor
    - rpm2archive: use size 0 for hardlinked files as bnew versions of
      gnu tar reject non-zero sizes [bsc#1269150]
    - backport fix for add_sysuser macro [bsc#1269571]
    - backport rpmuncompress security fix [bsc#1268747] [CVE-2026-44604]
    - switch from rpmpgp_legacy to libpgpr
      * multiple bug fixes, support for v5 and v6 signatures
    - turn on imaevm file signature support and move the imaevm code
      that needs the libimaevm library into a plugin. Put this
      plugin into a new rpm-imaevmsign subpackage. [jsc#PED-7246]
    - Fix unexpected EOF when using rpmbuild to install ELF binaries
      due to syntax error in /usr/lib/rpm/brp-strip. (boo#1259215)
    - Remove /var/lib/rpm migration scripting, retain an error if old
      location is found
    - Use systemd-tmpfiles to create & maintain /var/lib/rpm symlink
      (boo#1253139)
    - flush scriptlet notification messages in --runposttrans
      * needed to fix leaking tmp files [bsc#1218459]
      * added rpm_flushes_runposttrans provides for libzypp
