htmx 4.0: a Fetch-Based Rewrite, Built-In Morphing Swaps, and Explicit Attribute Inheritanceinfoq.com

htmx 4.0 replaces XHR with fetch (enabling streaming), adds built‑in morphing swaps via idiomorph, introduces hx‑partial for multi‑target updates, makes attribute inheritance explicit with a :inherited suffix, renames several attributes/events, adds a 60 s request timeout, and ships under npm's `next` tag with a CLI upgrade checker.
