Today, Sony updates the new firmware of PS Vita-3.63. There seems no big change. The changelog is “This system software update improves the quality of the system performance.”
For HENkaku user, please do not update your PS Vita to 3.63. As HENkaku is only accessible when you are in PS Vita 3.60. If you update console to the latest firmware, there will no way to hack your console again or downgrade it.
There is also good news that VHBL, custom themes, and the whitelist trick still work on 3.63.
