HTTP/3 is on, and it is ours: the fastest web protocol, built from scratch

Floati now speaks HTTP/3, the newest and fastest way browsers talk to the web, and it is an implementation we wrote from the ground up rather than borrowed. HTTP/3 is what most helps pages load on flaky wifi and mobile connections, where the older protocol stalls whenever a single packet is lost. Turning it on safely was the hard part: on networks that quietly block it (some offices, hotels and mobile carriers) Floati notices within about a second, drops back to the older protocol, and then stops trying the blocked path across the whole network, so you never wait. All of that detection happens on your device, with no extra traffic and nothing written to disk. Everything from the last release stays on too: the site name hidden from your network, cross-site cookie tracking shut down, and every certificate checked against the public record on your own machine.

What changed 3 changes

Networking	HTTP/3 by default, written from scratch. The protocol that keeps a page loading smoothly when the connection drops the odd packet (instead of stalling like the older one) is now on for every secure site that offers it. Floati's implementation is its own, built from the ground up, not a copy of an existing engine.
Networking	It never leaves you waiting on a network that blocks it. Some networks silently drop the kind of traffic HTTP/3 uses. Floati gives the new protocol about a second to answer, falls back to the older one the moment it does not, and then remembers that this network blocks it and stops trying, across every site, until you move to a different network. The check runs entirely on your device, sends no extra probes, and keeps nothing on disk.
Privacy & Shields	All the privacy from before, still on. The name of the site you open stays encrypted from your network where the site supports it, a tracker embedded on two different sites can no longer join up your visits through its cookie, and Floati checks on its own that every certificate was published to the public transparency record that catches forged ones.
