 If this is the first time you’ve heard of them, you might be surprised how important they are for real-world web compat!
 [**Over 40%**](https://webstatus.dev/features/aborting) of Google Chrome page loads at least *check* if they are supported, and many popular websites including GitHub and Discord are broken without them.
 
-**XPath** is now **enabled by default** (@simonwuelker, #40212), after implementing **‘@attr/parent’ queries** (@simonwuelker, #39749), completely rewriting the parser (@simonwuelker, #39977), and landing several other fixes (@simonwuelker, #40103, #40105, #40161, #40167).

 Servo now supports `new KeyboardEvent({keyCode})` and `({charCode})` (@atbrakhi, #39590), which is enough to get [**Speedometer 3.0**](https://browserbench.org/Speedometer3.0/) working on macOS.
 
@@ -43,6 +47,7 @@ Servo’s embedding API has had a few **breaking changes**:
 
 - <code>[Opts](https://doc.servo.org/servo_config/opts/struct.Opts.html)::wait_for_stable_image</code> was **removed**; to wait for a stable image, call <code>[WebView](https://doc.servo.org/servo/struct.WebView.html)::[**take_screenshot**](https://doc.servo.org/servo/struct.WebView.html#method.take_screenshot)</code> instead (@mrobinson, @delan, #39583).
 - <code>[MouseButtonAction](https://doc.servo.org/servo/enum.MouseButtonAction.html)::Click</code> was **removed**; use <code>[**Down**](https://doc.servo.org/servo/enum.MouseButtonAction.html#variant.Down)</code> followed by <code>[**Up**](https://doc.servo.org/servo/enum.MouseButtonAction.html#variant.Up)</code>. [Click events](https://developer.mozilla.org/en-US/docs/Web/API/Element/click_event) need to be *derived* from mouse button downs and ups to ensure that they are fired correctly (@mrobinson, #39705).
+- <code>[WebView](https://doc.servo.org/servo/struct.WebView.html)::set_pinch_zoom</code> was renamed to <code>[pinch_zoom](https://doc.servo.org/servo/struct.WebView.html#method.pinch_zoom)</code>, to better reflect that **pinch zoom** is always **relative** (@mrobinson, @atbrakhi, #39868).
 
 We’ve improved **page zoom** in our webview API (@atbrakhi, @mrobinson, @shubhamg13, #39738), which includes some **breaking changes**:
