* new upstream release, fixes
  * CVE-2007-1099: dropbear dbclient insufficient warning on hostkey
    mismatch (closes: #412899).
  * dbclient uses static "Password:" prompt instead of using the server's
    prompt (closes: #394996).

  Standards-Version: 3.7.2.2.
* debian/README.Debian: ssh -> openssh-server, openssh-client; remove

  installing the openssh-server package.
