This is literally one of the biggest jailbreak news in the last few years as it will enable jailbreaking newer versions of iOS on devices such as iPhone X for years to come. Unfortunately, I am out of luck as I have an iPhone XS :(
It is now possible to experiment with HTTP/3 thanks to some collaboration between Cloudflare and Google Chrome teams.
And of course, this site is HTTP/3 enabled for those who use Google Chrome Canary builds (at least for now).
It seems that Safari received support for USB/Lightning or NFC based FIDO2-compliant security keys in iOS 13.3 beta.
This makes using 2FA security keys much easier on iOS devices. Finally, I will be able to use NFC based security keys on my iOS devices.
Google experiments with new networking stack called Snap to replace TCP/IP on datacenters.
I wonder if this will end up as a draft somewhere like previous examples such as SPDY or QUIC. Of course, it is much harder to implement such a thing on the wild compared to a controlled environment such as a datacenter. However, this might spark some extra research in this area.
