r552:    * The "reverse hangover" release.
   * dh_strip: better documentation, removed extraneous "item" from SYNOPSIS.
     Closes: #162493
   * dh_strip: detect and don't strip debug/*.so files.
   * Note that 4.1.11 changelog entry was incorrect, dh_perl worked fine
     without that change, but the new behavior is less likely to break things
     if dpkg-gencontrol changes.
   * Various improvements to debhelper(1).
