Release Notes

bigskysoftware/htmx (org.webjars.npm:htmx.org)

v2.0.4

• Calling htmx.ajax with no target or source now defaults to body (previously did nothing)
• Nested shadow root fix
• The htmx:trigger event now properly fires on the synthetic load event
• The synthetic load event will not be re-called when an element is reinitialized via htmx.process()
• Boosted <form> tags that issue a GET with no or empty action attributes will properly replace all existing query
  parameters
• Events that are triggered on htmx-powered elements located outside a form, but that refer to a form via theform
  attribute, now properly cancel the submission of the referred-to form
• Extension Updates
  • preload extension was
    completely reworked
    by @​marisst to be compatible with hx-boost, not cause side effect, etc. Thank you!
  • response-targets was updated to not use deprecated methods
  • A small fix to
    ws to avoid an error when closing in some cases
  • The head-support extension was updated to work with the sse extension
