htmx 1.8.0 Release

I'm happy to announce the 1.8.0 release of htmx.

NOTE: This was a big release with some changes to very touchy code that is hard to test (e.g. history support) so please test thoroughly and let us know if there are any issues.

New Features

• The hx-replace-url attribute was introduced, allowing you to replace the current URL in history (to complement hx-push-url)
• m is now a valid timing modifier (e.g. hx-trigger="every 2m")
• next and previous are now valid extended query selector modifiers, e.g. hx-target="next div" will target the next div from the current element
• The HX-Location response header now implements client-side redirects entirely within htmx
• The HX-Reswap response header allows you to change the swap behavior of htmx
• The new hx-select-oob attribute selects one or more elements from a server response to swap in via an out of band swap
• The new hx-replace-url attribute can be used to replace the current URL in the location bar (very similar to hx-push-url but no new history entry is created). The corresponding HX-Replace-Url response header can be used as well.

Improvements & Bug fixes

• Boosted forms now will automatically push URLs into history as with links. The response URL detection API support is good enough that we feel comfortable making this the default now.
  • If you do not want this behavior you can add hx-push-url='false' to your boosted forms
• If htmx is included in a page more than once, we do not process elements multiple times
• When localStorage is not available we do not attempt to save history in it
• hx-boost will boost anchor tags with a _self target
• The load event now properly supports event filters
• The websocket extension has had many improvements: (A huge thank you to Denis Palashevskii, our newest committer on the project!)
  • Implement proper hx-trigger support
  • Expose trigger handling API to extensions
  • Implement safe message sending with sending queue
  • Fix ws-send attributes connecting in new elements
  • Fix OOB swapping of multiple elements in response
• htmx now properly handles anchors in both boosted links, as well as in hx-get, etc. attributes
• Many, many documentation updates (thank you to all the contributors!)

Enjoy!
