This post outlines what's going on (although it's a little out of date): https://htmx.org/essays/the-fetchening/ https://htmx.org/essays/the-fetchening/ Basically the core API will remain nearly identical, but we're moving the internals to fetch() which will allow us to support streaming responses, take advantage of the async infrastructure in JS to simplify things, etc. Hopefully most htmx users won't notice much different when they upgrade.
