Released:November 6th, 2012
This update fixes some bugs introduced in the past, particularly where the content filter backup and the regular backup are concerned. It turns out that any custom images uploaded to the contentfilter and any custom black/white lists were not part of the back ups.
It is recommended that all NetSentron’s be updated to 3.3.8 before updating to the 4.x series of NetSentron because of these issues. If you do not have any custom images or customer black/white lists, then you can safely upgrade to 4.x using 3.3.6 or newer.
