On my report page, I get a warning about Unsupported Release of modules or themes.
but when I click the "available updates" link, the next page tells me that all my projects are up to date.
I've tried clearing my cache and running cron but I get the same result.
Apparently this is a known bug that I missed in my searches. Unfortunately, the link to the bug below doesn't include any info on how to find out WHICH modules are unsupported. :( So, I have no way to figure out which things I need to upgrade or remove.
Where can I find a list of the unsupported modules in my installation?
