Is there an issue with debug mode in 2.4? We've recently updated and now find that in debug mode we sometimes don't get the expected stack trace on error.

With a 500.twig file in place it displays that, otherwise we get the default Internal Server Error summary view.

Is this something that broke in the recent update?
There is a bug in the current release that's been fixed for the next one where PHP Errors/Warnings/Notices won't have the full stack trace shown even if the site is in devMode.
