 =================
  * The -N, --force-nocopy option now also works if you used previously
    "sync" commands without it.
- * When saving the content file keep a copy of the previos one adding
-   the ".backup" extension.
  * Added a new -F, --force-full option that forces a full sync reusing
    the hash data present in the content file.
    This may be useful when using an old content file like the backup
