+- **createWebhookVerifyPayload** — Written manually. No GitHub PR exists for this change; the commit was made directly to the release branch. The change exports `createWebhookVerifyPayload` from `@webiny/sdk/webhooks` (not the root barrel, which is browser-safe).

+### Exported `createWebhookVerifyPayload` from `@webiny/sdk/webhooks`
+
+The `createWebhookVerifyPayload` function is now exported from `@webiny/sdk/webhooks`. It was previously inaccessible, making it impossible to verify webhook payloads in API-only code.
+
+It is intentionally not re-exported from the root `@webiny/sdk` barrel because it is API-only — the rest of the SDK is also safe to use in the browser and admin UI.
+
+```typescript
+import { createWebhookVerifyPayload } from "@webiny/sdk/webhooks";

+- how to upgrade Webiny from 6.4.x to 6.4.1
+

+<Alert type="info">
+
+Make sure to check out the [6.4.1 changelog](./changelog) to get familiar with the changes introduced in this release.
+
+</Alert>
+
+## Step-by-Step Guide
+
+### 1. Upgrade Webiny Packages
+
+Upgrade all Webiny packages by running the following command:
+
+```bash
+yarn webiny upgrade 6.4.1 --debug
+```
+
+Note that the command above will run upgrades for all available versions of Webiny up to 6.4.1. If there are upgrades for 6.4.1, 6.4.5, they will be ran.
+
+You can omit the version to upgrade to the latest available:
+
+```bash
+yarn webiny upgrade --debug
+```
+
+Once the upgrade has finished, running the `yarn webiny --version` command in your terminal should return **6.4.1**.
+
+<Alert type="info">
+
+If the above command fails or is not available in your setup, you can run the upgrade script directly via `npx`:
+
+```bash
+npx https://github.com/webiny/webiny-upgrades-v6 6.4.1 --debug
+```
+
+</Alert>
+
+### 2. Deploy Your Project
+
+Proceed by redeploying your Webiny project:
+
+```bash
+# Execute in your project root.
+yarn webiny deploy --env {environment}
+```
