What breaks

After the end of support date, function apps on PowerShell 7.4 continue to run, but security patches and updates are no longer provided and customer support for PowerShell 7.4 is discontinued. Microsoft states that running function apps on an unsupported runtime or language version may lead to issues and degraded performance. Apps on a Linux Consumption plan must first upgrade to the Flex Consumption plan before upgrading to PowerShell 7.6.
