Dropping tcp_wrappers support

tcp_wrappers support is being dropped from all packages and the package removed from [core]. This is due to upstream not having released a new version since April 1997. Additionally, newer daemons and applications are inconsistent in their support for libwrap, leading to confusion as to whether an application supports the library.

If you currently use /etc/hosts.allow or /etc/hosts.deny for security or logging purposes, you will need to adjust accordingly and use another tool such as iptables, or other firewall helper programs.

Additionally, the denyhosts package will be dropped as it depends on tcp_wrappers to enforce the banned hosts list. A useful alternative is fail2ban.
