Resolution

In Sugar 11.2 (Q4 2021), Sugar upgraded from Smarty library v2.6.11 to v3.1.35. Significant changes exist between Smarty 2.x to 3.x, and the Sugar upgrader was configured to identify known incompatibilities with Smarty 3.x and make automated updates to fix the templates.

The upgrader will generate warnings whenever it has migrated a custom Smarty template and will also generate warnings if it encounters anything unusual such as outdated Smarty syntax in a PDF template.
