Oxygen 4.9.7 RC 1 Now Available
This release focuses on stability and PHP 8.3 compatibility, resolving a number of warnings and deprecated notices across core elements and templates.
Fixes include issues with undefined array keys and variables in elements such as Icon Box and Social Icons, as well as improvements to template handling where null values could trigger warnings.
We’ve also addressed element duplication behaviour to ensure nicenames correctly match element IDs when copying or importing content.
You’ll find the full changelog below. As always, please report any issues you encounter by opening a support ticket at https://oxygenbuilder.com/support/.
