      The document abstract

WebSub provides a common mechanism for communication between publishers 
of any kind of Web content and their subscribers, based on HTTP web 
hooks. Subscription requests are relayed through hubs, which validate 
and verify the request. Hubs then distribute new and updated content to 
subscribers when it becomes available. WebSub was previously known as 
PubSubHubbub.

conforming implementations of PubSubHubbub 0.4 
<https://superfeedr-misc.s3.amazonaws.com/pubsubhubbub-core-0.4.html>. 
During CR's testing phase we will gather feedback on how completely this 
goal was met.
