HFW 4.86.1 Released for PS3

From a hacking point of view, Firmware 4.86 doesn’t seem to affect much since the kernel wasn’t changed at all.
Joonie has confirmed that FW 4.86 doesn’t come with any kernel changes and released HFW 4.86.1 (Link)

This, in turn, prompted Joonie to state that an update to PS3HEN should be expected soon so that you could hack your noCFW (min FW of 3.60+) PlayStation 3 console. Furthermore, Joonie has released HFW 4.86.1 which is exactly the same as OFW 4.86 but with a modification to the web browser making it vulnerable to exploits employed to hack your console. This means that all PlayStation 3 consoles are still hackable as the current firmware is still vulnerable to current exploits!
However, if you can get by with spoofing your firmware version and staying on an older firmware, you should probably do so for now as some homebrew utilities may not function correctly as offsets might need to be updated. Updates to popular homebrew utilities and CFWs may not take long similar to what happened when Firmware 4.85 was released last August.
