Playstation 3 Firmware 4.11 Released February 16, 2012

A not yet required release has quietly been phased into the Playstation 3 update program in the form of Firmware Update 4.11.  When I say quietly I mean very quietly, there is no notification of the update during Playstation Network login.  The only way you would know the update was there would be to check the Firmware Update program manually.  No patch notes were included with the update, so it is unclear what, if anything the update is supposed to do or fix.

From what I have researched, the firwmare is not required to access the Playstation Network in the United States, but it is required to use the Playstation Network in other nations.
