* Security fix. Thanks Matt B!
* Changed what we consider to be private addresses to a smaller range of addresses. See current range at: http://docs.wordfence.com/en/How_Wordfence_handles_Private_Addresses
* Fixed a warning about an undefined value which appeared after we added referer blocking in 5.3.2.
