I was hit with a couple of bugs: hx-on not properly de-initializing, with a workaround in 43fffb68 and properly fixed with version 1.9.2; and elements with naked hx-trigger did not work with hx-boost, as i do for the tag inline form, fixed in 1.9.1. The other bug fixed in 1.9.1, play well with other libraries that also use the window.onpopstate, did not affect me, i believe.
