Joomla 3.6 support. Joomla 3.6 has changed the location of the logs directory. This version addresses this change.
Workarounds for Joomla issues regarding caching and email sending.
Preparation for Admin Tools 4. Due to the way Joomla updates worj you will need to install this version first. The update site definition will be replaced with the one for Admin Tools 4 so you'll be notified when it's released and be able to update to it with one click. If you do not install Admin Tools 3.8.4 you will NOT be able to update to Admin Tools 4 through Joomla's extensions updater.
Despite our policy of only allowing installation on the latest Joomla! release, this version will run on Joomla! 3.0, 3.1, 3.2, 3.3, 3.4, 3.5 and 3.6 to mitigate the major security issues discovered in Joomla! in October and December 2015. We VERY STRONGLY advise you to update to the latest released version of Joomla! at all times. Admin Tools' support for old versions of Joomla! is only meant to be a temporary workaround while you're working on the update of your site.
Please note that we will only provide full support for the latest Joomla! version. Some features –like the Change administrator directory– may not work at all in older Joomla! versions. We've thoroughly tested the security critical Web Application Firewall features against older releases of Joomla! and found them to be working properly.
This version requires PHP 5.3.4 or later (e.g. 5.3.29 which is twenty five versions newer than PHP 5.3.4), 5.4, 5.5 or 5.6. Please note that PHP 5.3 is obsolete since August 2014 and we're going to stop supporting it without warning in future versions of our software. We'd like to remind you that Joomla! 3.4 does not currently support PHP 7. You need Joomla! 3.5 to run Joomla! and Admin Tools on PHP 7.
Note: there is no such thing as PHP 6. PHP versions jumped from 5.6 to 7.0. Why? Well, it's a long story. TL;DR: It doesn't have to make sense, just accept it.
