If you are a maintenance client of Joomstore you may have noticed we have applied 3 separate Joomla updates to your site over the past few weeks.
Joomla released version 3.4.6 on December 14 to address a security vulnerability discovered in PHP. Hackers discovered a way to exploit this vulnerability in Joomla. The issue was further addressed by Joomla with patch 3.4.7 and then 3.4.8 on Christmas eve which we applied that day.
