According to the article, there is a yellow checkmark for Pi 4 for Stretch (if it is upgraded to the 2019-04-08 release).
I'm curious what limitations the Pi 4 has in this state.

My understanding is that there is new code required to support the RPi4 and that code is only delivered in Buster. If you need Stretch, you'll need to run it on earlier Pi hardware. You may get it to work, but why bother with possible limitations and degraded operation? If you have software that doesn't run on Buster, it's time to move it forward (or ask the developer to do so).

Yes, I once hoped that Stretch can run on my Rpi4, so I can run some old drivers which have not caught up with Buster. But now I think I better be patient and wait for the old drivers to catch up soon.– tlfong01Aug 6, 2019 at 0:45

This makes sense but I'm curious to know why there even is a yellow checkmark, as it doesn't seem to progress very far in the boot sequence. But it's possible that I did not upgrade the Stretch install properly. Aug 6, 2019 at 2:26

could you provide a link referencing the "there is new code required to support RPi4"? I have the same understanding but I can't find where I'd originally read it.– MarcNov 4, 2019 at 17:04

1@Marc Although not RPF confirmation, I did find this: raspberrypi.org/forums/… . This was my understanding as well.– blsNov 6, 2019 at 0:11
I have just released a script that will run a Raspbian Stretch virtual machine, inside the Raspbian Buster operating system. Not sure if it will work in your case, but it is definitely something to try if you don't want to wait for drivers to catch up.
sudo apt update && sudo apt upgradeon a Pi 3 with it, it still does not boot my new Pi 4. Hmm.sudo apt update && sudo apt upgrade && sudo apt dist-upgrade- maybe they will still work after the upgrade? Worth a shot.
