------------------
This release marks a breaking change. Now the script "tags" recorded entries in
the security groups, e.g. ``[ip-liberator] SSH John`` instead of only ``SSH John``.
That helps to identify what IP Liberator added and what was added by hand.
By default, the tag is **ip-liberator**, but can be change through the new
option ``--tag``. If the user wants the previous behavior, i.e. without a tag,
he or she must pass the option ``--no-tag``.
