HTTP/3 for Web Developers.
HTTP/3 is the latest evolution of the HTTP protocol and provides some exciting new features ont op of those that HTTP/2 brought to us. So the main =update we have is a change from using TCP to use QUIC and UDP. This allows HTTP/3 to handle 'head of line blocking' much better than HTTP/2 and only pause the single stream that has lost a packet, allowing other streams to continue downloading. This is great for environments where your internet connection is a bit sketchy!
There are also improvements to the initial handshake speed and also to switching between different networks.
For Web Devs these changes should all be transparent with no changes to the way we configure our websites, unlike when we moved to HTTP/2 and this required some explicit setup in order to use (for say push or different code splitting options)
HTTP/3 is enabled in the Safari already, and currently behind a flag in Chrome/Firefox/Edge. Feel free to turn these on to test out HTTP/3 yourself!
