Htmx 2.0.4 has introduced several changes, including a notable modification where calling htmx.ajax without a target defaults to the body element, which raises concerns about potentially breaking existing implementations. Users have mixed feelings; some praise Htmx for bridging simple interactivity without complex frameworks, while others highlight limitations for more complex client-side state management and interactivity. There is discussion about when Htmx suffices versus scenarios that require traditional JavaScript frameworks like React or Svelte. Overall, the release emphasizes a balance between enhancing traditional server-side rendering and recognizing Htmx's limitations in highly interactive environments.
