Is RPi4 USB boot now released as operational or is it still in beta?

The beta phase has ended, the code is available with apt, but there has not been an Announcement (AFAIK), and you still have to do some configuration:

Thank you - there seem to be a multitude of threads about this topic and I found it difficult to find a clear status.

It is available in the stable software channel (with apt), but the RasPiOS image has not been updated to support it yet, so you need to manually configure it and also update RasPiOS itself to support it. Because of that, one of the engineers said it could still be considered beta. They are working on a new image with full support, but it works great now if you don't want to wait.

Here is a more recent post of mine describing how to set it up and configure it.

I have tested it with several SSD models and a Samsung BAR Plus 64GB USB 3.1 flash drive. The Samsung flash drive worked well and was faster than an SD card, but it can't compare to the performance of an SSD. Even my SP A55 budget SSD clobbers the performance of the Samsung flash drive (or any micro SD card).
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups, and where is that annoying music coming from?

Again, my thanks for another helpful reply.

I’m keen to get to SSD boot but I think I’ll wait until it’s all packaged.
