The first one, I can fix my downgrading PHP to 8.4, but CP 2.6.0 is fully compatible with PHP 8.5. I tested it. There might be edge cases, but this plugin is targeted towards developers anyway, so I’m sure we can bump PHP to 8.5.
And the second one, the highlighted link points to a 404 page.
I could fix this myself, if you pointed me to the right repository.
