# Update History:
# 2019/05/21 Updated to support version 3.1
# including patches so it works with Slackware. Since being
# forked from v2.6 the project name changed to denyhost on sourceforge
# (used for source downloads)
# and is homed on github https://github.com/denyhosts/denyhosts
# but programs still have the same name. default config file
# has moved to /etc and changed from denyhosts.cfg to denyhosts.conf
# programs have moved to /usr/sbin. Also iptables support
# has been added.
