htmx 1.2.0 Release

I'm happy to announce the 1.2.0 release of htmx.

New Features & Major Changes

• hx-vars has been deprecated in favor of hx-vals
• hx-vals now supports a javascript: prefix to achieve the behavior that hx-vars provided
• The new hx-headers attribute allows you to add headers to a request via an attribute. Like hx-vals it supports JSON or javascript via the javascript: prefix
• hx-include will now include all inputs under an element, even if that element is not a form tag
• The preload extension now offers a preload-images="true" attribute that will aggressively load images in preloaded content
• On requests driven by a history cache miss, the new HX-History-Restore-Request header is included so that the server can differentiate between history requests and normal requests

Improvements & Bug fixes

• Improved handling of precedence of input values to favor the enclosing form (see here)
• Moved event filtering logic after preventDefault so filtering still allows events to be properly handled
• No longer trigger after swap events on elements that have been removed via an outerHTML swap
• Properly remove event handlers added to other elements when an element is removed from the DOM
• Handle the scroll: modifier in hx-swap properly when an outerHTML swap occurs
• Lots of docs fixes

Enjoy!
