htmx 1.7.0 Release

I'm happy to announce the 1.7.0 release of htmx.

New Features

• The new hx-sync attribute allows you to synchronize multiple element requests on a single element using various strategies (e.g. replace)
  • You can also now abort an element making a request by sending it the htmx:abort event
• Server Sent Events and Web Sockets are now available as extensions, in addition to the normal core support. In htmx 2.0, the current hx-sse and hx-ws attributes will be moved entirely out to these new extensions. By moving these features to extensions we will be able to add functionality to both of them without compromising the core file size of htmx. You are encouraged to move over to the new extensions, but hx-sse and hx-ws will continue to work indefinitely in htmx 1.x.
• You can now mask out attribute inheritance via the hx-disinherit attribute.
• The HX-Push header can now have the false value, which will prevent a history snapshot from occuring.
• Many new extensions, with a big thanks to all the contributors!
  • A new alpine-morph extension allows you to use Alpine's swapping engine, which preserves Alpine state when you have entire Alpine components swapped by htmx.
  • A restored extension was added that will trigger a restore event on all elements in the DOM on history restoration.
  • A loading-states extension was added that allows you to easily manage loading states while a request is in flight, including disabling elements, and adding and removing CSS classes.
• The this symbol now resolves properly for the hx-include and hx-indicator attributes
• When an object is included via the hx-vals attribute, it will be converted to JSON (rather than rendering as the string [Object object]")
• You can now pass a swap style in to the htmx.ajax() function call.
• Poll events now contain a target attribute, allowing you to filter a poll on the element that is polling.
• Two new Out Of Band-related events were added: htmx:oobBeforeSwap & htmx:oobAfterSwap

Improvements & Bug fixes

• Many, many documentation updates (thank you to all the contributors!)

Enjoy!
