The new version broke mods that rely on detecting the OS to decide which libs to load. Specifically, ACE3 won't work at all now instead of just disabling parts of it that don't have a native library.
To quote the person who actually found the problem:
15:04 ***: productVersion on the newest linux release returns Windows instead of Linux, breaking some mods.
15:04 ***: there's your text
He's not willing to take time to report this, unfortunately, and I'm not sure how to demonstrate the problem clearly.
