Since Sony's last update we saw the E3 Share and PS4Kit clones to the MTX Key ModChip for gamesharing, and today Sony has once again updated the PlayStation 4 Official Firmware to version 4.73 bringing the most stable OFW to date! 
While PS4 scene developers examine it to see what was changed and patched, some may want to give the PSProxy Bypass a try as it often works for a few days during Firmware transitions when the Passphrase changes.
Update: Reports of confirmations are coming in that MTX Key is blocked in PS4 Firmware 4.73, currently we're awaiting additional confirmations so if you update and try it let us know your results in the comments thanks!
Update #2: More reports are confirming with video proof Sony has blocked the MTX Key ModChip, gamesharing method and issuing bans on some PS4 consoles... more to come as it's available!
Update #3: Despite a contrary video, both the MTX Key and clones of it have been confirmed to be disabled by most rendering yet another for-profit device useless for the time being with more PSN account bans being reported!

Finally, PlayStation 4 hacker qwertyoruiop recently stated the following on Reddit, to quote:
"My 4.5x webkit works fine on 4.7x (unchanged, even!). It is. 4.06 has both a public webkit and a private working kernel exploit. My kernel exploit doesn't work on 4.70. bug is there, but exploit technique was killed"
