Version 11 Stable is released recently and now hosted at upstream/master branch.
if you are interested in testing and reporting bugs.
Simply run to upgrade Frappe/ERPNext from frappe-bench equivalent directory, those who switched to staging branch during Beta.
bench switch-to-master
bench update --requirements
bench update --patch
You may switch back to master branch by doing bench --site your-site-name switch-to-master followed by bench update --patch && bench migrate or simply bench retry-upgrade
Note: Beta Version 11 is out of Beta and it is available at master branch and develop branch started with Version 12 development.
