Abstract
First published by the W3C in January of 2018, ActivityPub has been the protocol that binds the Fediverse together. The hard-won experience of hundreds of developers, who have taken the words of the spec and turned it into a living network, is spread across forums, blog posts, chat rooms and toots. The W3C has authorized a new release of the specification, with updated text, examples, and clarifications. This talk will cover what's coming with ActivityPub 1.1 and what you need to know to get ready for it.

Evan is the Research Director at the Social Web Foundation. He first engaged with the Fediverse when launching the identi.ca project in 2008. He co-authored OStatus and ActivityPub, and chaired the Social Web Working Group at the W3C from 2014 to 2018. Today, he maintains the ActivityPub and Activity Streams specifications, leads efforts to bring end-to-end encryption and private groups to the Fediverse, and builds infrastructure like tags.pub to make the Fediverse better and more interesting. He wrote the book "ActivityPub: Programming for the Social Web" (O'Reilly Media, 2024) to help developers understand and use the protocol.
