@@ -29,6 +29,26 @@ we should rename this section to "Unreleased" -->
 The following changes only apply when using `sentry-cli` via the npm package [`@sentry/cli`](https://www.npmjs.com/package/@sentry/cli):
 
 - Drop support for Node.js <18. The minimum required Node.js version is now 18.0.0 ([#2985](https://github.com/getsentry/sentry-cli/issues/2985)).
+- The type export `SentryCliReleases` has been removed
+- The JavaScript wrapper now uses named exports instead of default exports ([#2989](https://github.com/getsentry/sentry-cli/pull/2989))
+. You need to update your imports:
+  ```js
+  // Old (default import)
+  const SentryCli = require('@sentry/cli');
+
+  // New (named import)
+  const { SentryCli } = require('@sentry/cli');
+  ```
+
+  For ESM imports:
+  ```js
+  // Old
+  import SentryCli from '@sentry/cli';
+
+  // New
+  import { SentryCli } from '@sentry/cli';
+  ```
