# Changelog

* pf-badhost goes portable! Supported OS now include:
	* OpenBSD
	* FreeBSD
	* DragonflyBSD
	* NetBSD
	* MacOS

* Improved customizability -- Added a "User Configuration Area" 
  to the script to allow users to easily enable features and/or 
  add custom lists or rules to their blocklist

* IPv6 subnet aggregation support added

* Added IPv4 and IPv6 Bogon filters

* Be extra paranoid -- have ftp(1) output to stdout to allow it 
  to drop all disk/filesytem pledges, which creates a stronger 
  form of unveil (unveil returns ENOENT, whereas pledge will 
  kill ftp(1) if it tries to access the disk) 

* Script now calculates total number of IP addresses contained 
  within the blocklist, and prints the result.

* Numerous correctness and error handling improvements

* Rewrote IPv6 address validator as POSIX regular expression

* Removed Perl as a mandatory dependency

* Geoblocking now pulls data directly from ARIN, APNIC etc
