Version 3.6.0 - Unpoly

Targeting fragments

Unpoly-specific pseudo selectors like :main or :layer can now be used in a compound target, e.g. :main .child.
Targeting :main will no longer match in the region of the interaction origin. It will now always use the first matching selector in up.fragment.config.mainTargets.
Fix a bug where following a navigation item outside a main element would focus the <body> instead of the main element.

Performance improvements

Unpoy now uses the native :has() selector where available. Unpoly's polyfill for :has() will remain included for the time being. It will be removed as Firefox' :has() support has reached the majority of users (available on Nightly now).
Improve performance of many element lookups, by finding elements via CSS selectors (vs. filtering lists with JavaScript).

Support for structured data markup

Structured data in script[type="application/ld+json"] elements is considered a meta tag that will be updated with history changes.
script[type="application/ld+json"] elements in are now preserved in new fragments with up.fragment.config.runScripts = false.

Bugfixes and minor improvements

CSP nonces embedded into attribute callbacks now work with Content-Security-Policy-Report-Only.
When the X-Up-Validate header value exceeds 2048 characters, it is now set to :unknown. This is to prevent web infrastructure from rejecting an overly long request line with an 413 Entity Too Large error.
Fix a bug where up:assets:changed would be emitted for every response when configuring up.fragment.config.runScripts = false.
up.form.isSubmittable() now returns false for forms with a cross-origin URL in their [action] attribute.
up.util.contains() now works on NodeList objects.
You can now configure which elements are removed by up.fragment.config.runScripts = false.

Upgrading

If you're upgrading from an older Unpoly version you should load unpoly-migrate.js to polyfill deprecated APIs. Changes handled by unpoly-migrate.js are not considered breaking changes.
