With the release of version 16 of ERPNext, version 14 has reached end of life as of today. This means that version 14 is no longer covered under Frappe Support and will not receive the latest bug fixes anymore. We highly recommend you to update to v16 to stay upto date with the newest features, bug fixes and avail Frappe’s Support services. Here’s the migration guide for the same and here is the one for the Frappe Framework.
If you’re on Frappe Cloud, here is a guide that will help you perform a version upgrade.

Frappe Team
