 ```
 
+- **feat(core): Return client from init method (#12585)**
+
+`Sentry.init()` now returns a client directly, so you don't need to explicitly call `getClient()` anymore:
+
+```js
+const client = Sentry.init();
+```
+
+- **feat(nextjs): Add `deleteSourcemapsAfterUpload` option (#12457)**
+
+This adds an easy way to delete sourcemaps immediately after uploading them:
+
+```js
+module.exports = withSentryConfig(nextConfig, {
+  sourcemaps: {
+    deleteSourcemapsAfterUpload: true,
+  },
+});
+```
+
+- **feat(node): Allow to configure `maxSpanWaitDuration` (#12610)**
+
+Adds configuration option for the max. duration in seconds that the SDK will wait for parent spans to be finished before
+discarding a span. The SDK will automatically clean up spans that have no finished parent after this duration. This is
+necessary to prevent memory leaks in case of parent spans that are never finished or otherwise dropped/missing. However,
+if you have very long-running spans in your application, a shorter duration might cause spans to be discarded too early.
+In this case, you can increase this duration to a value that fits your expected data.
