-###### Auto-generated view transition names
-
-The `view-transition-name` CSS property supports two new values, to avoid having to invent unique names for elements that participate in a view transition:
-
-* `match-element` - Generates a unique ID that's based on the element's identity.  This value is useful in single-page apps where the element that's animated with a view transition is being moved in the DOM.
-
-* `auto` - Generates a unique ID that's based on the element's `id` attribute.  This value only takes the `id` attribute into account, and ignores the type of element.  This approach enables a view transition to work across multiple pages of an app, where elements with the same `id` attribute may be of different types.

-###### Ignore `letter-spacing` in cursive scripts
-
-Per specification, the browser now ignores the `letter-spacing` CSS property when rendering cursive scripts, to avoid breaking words.
-
-If possible, the browser may apply letter spacing by translating the extra space into cursive elongation or compression.  If the text cannot be expanded without breaking cursive connections, the browser treats each word as a single typographic unit for letter spacing.
-
-Proper cursive elongation or compression varies, based on:
-* Script.
-* Typeface.
-* Language.
-* Word location.
-* Line location.
-* Implementation complexity.
-* Font capabilities.
-* Calligraphic preferences.
-
-Proper cursive elongation or compression may involve shortening:
-* Ligatures.
-* Swash variants.
-* Contextual forms.
-* Elongation glyphs.
-
-Avoid applying the  `letter-spacing` property to cursive scripts, unless you can accept non-interoperable results.

-See [letter-spacing](https://developer.mozilla.org/docs/Web/CSS/letter-spacing) at MDN.

-###### Call stacks in crash reports from unresponsive web pages
-
-When a webpage becomes unresponsive due to JavaScript code running a very long computation, such as an infinite loop, the Javascript call stack is recorded and included in the crash report that's sent to the Reporting API server endpoint that's configured by the website.
