+Driver version is read from [scripts/CLI_VERSION](https://github.com/microsoft/playwright-java/blob/main/scripts/CLI_VERSION) and can be found in the upstream [GHA build](https://github.com/microsoft/playwright/actions/workflows/publish_canary.yml) logs. To update the driver to a particular version run the following commands:
+
+```bash
+cat > scripts/CLI_VERSION
+<paste new version>
+^D
+./scripts/download_driver_for_all_platforms.sh -f
+./scripts/generate_api.sh
+./scripts/update_readme.sh

+ *   }

+ *
+ * <p> Playwright will be re-testing the node with the selector {@code .status} until fetched Node has the {@code "Submitted"} text. It
+ * will be re-fetching the node and checking it over and over, until the condition is met or until the timeout is reached.
+ * You can pass this timeout as an option.
+ *
+ * <p> By default, the timeout for assertions is set to 5 seconds.
