HEN 14.02A video posted on November 5 shows a HEN loading from the browser on 14.02, the firmware Sony shipped a day earlier. Its author says he won't be releasing anything.
GoldHEN 14.00The WebKit chain that covered 13.02 to 13.52 now reaches 14.00 through a GoldHEN beta released on November 3. Sony shipped 14.02 a day later with security fixes and no public method exists for it, so stay on 14.00 or lower.
FW 14.22Version 26.07-14.22.00 arrives less than two weeks after 14.20 with no visible changes. No 14.x firmware has a public exploit, so anyone on 13.60 or lower who wants homebrew should not update.
