Since their previous update last month, today Sony pushed a PS4 System Software / Firmware 4.55 Update (confirmed as non-mandatory at this time by @VultraBabe) live which appears to be another of their infamous stability updates to 'improve the quality of the system performance' which may fix the WiFi issue and patch exploit holes. :eyerolling:

Download: PS4 Firmware 4.55 Update (US) / PS4 Firmware 4.55 Update (EU) / PS4 Firmware 4.55 Update (UK) / PS4 Firmware 4.55 Update (AU/NZ) / PS4 Firmware 4.55 Update (JP)

:alert: We'll update this article once we catch word on whether the JailbreakMe PS4 WebKit Userland Exploit, PS4 4.50 Kernel Read / Write Exploit or the Rumored Brazilian PS4 4.50 GameSharing Method is confirmed to be patched in OFW 4.55... until then, as usual it's recommended not to update your PlayStation 4 console.

Changelog via PS4Firmware.com: Main features in version 4.55 update
  • This system software update improves the quality of the system performance.

Nothing new ? Of course there is ! It is not the usual 4.55 BPF UAF kexploit, but a backport of the 5.05 BPF Double Free kexploit ! Now 4.55-5.07 use same webkit exploit and same kernel exploit !
Cheers to @Centrino, @DarkElementPL, @guido970, @Jeff and @simobuoncuo in the PSXHAX Shoutbox for sharing the news this morning! <3

if this update is non-mandatory i doubt it patches any exploit, if it did why why would sony not have it being mandatory? makes no sense

It isn't mandatory at this time, eventually it will be though... usually in a few days or week tops, you can tell by monitoring the ps4-updatelist.xml, specifically:
Code:
<force_update><system level0_system_version="04.508.000" level1_system_version="04.508.000"/></force_update>
