[1.9.4] - 2023-07-25

• This is a bug-fix release for the most part, w/a heavy dose of @​telroshan
• The HX-Trigger response header now supports comma separated event names
• Submit buttons that use the form attribute now work correctly
• The changed modifier now uses the triggering element, rather than the element the hx-trigger is defined on
• hx-disable is now handled dynamically so it can be added and removed
• IE11 compatibility restored! (maybe, hard to test)
• Fixed bug with hx-on event handler cleanup
• Many smaller bug fixes, typo fixes and general improvements
