Howdy Folks,

We’re thrilled to announce that the beta releases of iOS 14 and macOS Big Sur include experimental support for HTTP/3! There are options to enable HTTP/3 in Safari as well as for development versions of your applications. On Friday, there is a WWDC session, Boost performance and security with modern networking <https://developer.apple.com/wwdc20/10111>, which includes more details. In the meantime, the iOS 14 beta Release Notes <https://developer.apple.com/documentation/ios-ipados-release-notes/ios-ipados-14-beta-release-notes> and macOS Big Sur beta Release Notes <https://developer.apple.com/documentation/macos-release-notes/macos-big-sur-11-beta-release-notes> contain instructions for enabling HTTP/3.

Currently, draft-27 is supported. Please try it out during these early betas and send us feedback before the general release. You can do this from Feedback Assistant <https://feedbackassistant.apple.com/> or in the #applequic Slack channel.

Cheers,

Ryan
