+- **feat(core): Add `ignoreSpans` option ([#17078](https://github.com/getsentry/sentry-javascript/pull/17078))**
+
+This release adds a new top-level `Sentry.init` option, `ignoreSpans`, that can be used as follows:
+
+```js
+Sentry.init({
+  ignoreSpans: [
+    'partial match', // string matching on the span name
+    /regex/, // regex matching on the span name
+    {
+      name: 'span name',
+      op: /http.client/,
+    },
+  ],
+});
+```
+
+Spans matching the filter criteria will not be recorded. Potential child spans of filtered spans will be re-parented, if possible.
