Just wanted to inform that after version 14 release, fixes will not be backported to version 12.
If you are using version 12 or older, it is recommended to upgrade to version 13 or version 14 to get regular bug fixes, performance improvements and minor features.
While upgrading you might want to checkout following migration guides.
This involves changes you’d have to make in your Frappe Apps to make them compatible with the latest releases of Frappe.
Note: Please upgrade one major version at a time (multiple major version upgrade is not supported)
eg. If you are on version 12 and want upgrade to version 14, make sure to first upgrade to v13 and then to v14.
