| - The {{domxref('PointerEvent.altitudeAngle','altitudeAngle')}} and {{domxref('PointerEvent.azimuthAngle','azimuthAngle')}} properties of the {{domxref('PointerEvent')}} interface are supported, providing the angle between the pointer/stylus and the screen (X-Y plane), and the rotation of the stylus over the screen relative to its x-axis, respectively. ([Firefox bug 1656377](https://bugzil.la/1656377)). | |||
| - [Text fragments](/en-US/docs/Web/URI/Fragment/Text_fragments) are now supported, allowing users to link to and highlight specific portions of text in a web page. This feature uses a particular syntax in the [URL fragment](/en-US/docs/Web/URI/Fragment) that identifies the target based on patterns in the rendered text. | |||
| Website developers can also use the existence of the {{domxref("Document.fragmentDirective")}} property (an instance of the {{domxref("FragmentDirective")}} interface) to feature check for text fragment support, and the {{CSSxRef("::target-text")}} pseudo element to select and style text that has been selected using a text fragment link. ([Firefox bug 1914877](https://bugzil.la/1914877)) | |||
| - The {{domxref('Document/caretPositionFromPoint','caretPositionFromPoint()')}} method of the {{domxref("Document")}} interface has been updated so that it can return the text node and offset for a caret position within a shadow DOM, provided the shadow root has been supplied to the method. ([Firefox bug 1914596](https://bugzil.la/1914596)). | |||
There was a problem hiding this comment.
I’d mention that it has been updated to include a third argument. Currently, it focuses on the return value, but there used to be only two arguments, which is also new.

FF131 adds support for "new shadow dom behaviour" in
Document.caretPositionFromPoint()in https://bugzilla.mozilla.org/show_bug.cgi?id=1914596Essentially this means a new option, called
optionshas been added the the api, along withx,y. The option allows a caller to supply a list of shadow roots, which allows the caret position to be resolved (or not, if not supplied).This just adds the release note.
