We are currently still preparing for a Raspberry Pi 4 version of our software, but we have progressed into early Alpha testing. We plan to support Screenly on the Pi 4 as soon as possible, and while we have not committed to an ETA we hope this will be ready sometime in Q4 2021. We still remain very excited about the possibilities that the Pi 4 will offer.
If you are interested in being a beta tester for Screenly (paid) on the Pi 4, please submit a support ticket with the subject "Pi 4 Beta Tester" expressing your interest, and we will notify you about opportunities as they come up.
If you are looking for more information on running OSE (free) on the Pi 4, please check on the GitHub page https://github.com/Screenly/screenly-ose/issues for the latest information. Please note that we do not provide support for OSE, so it is always best to ask questions related to this on one of the OSE support platforms.
