It is not. Original SE version has been been superceded by MDx model a few years back (easy way to tell them apart is the Ethernet input on the later).This product is on sale right now. You can get it with or without the SE revision. So it doesn't matter that the original came out a while ago. it is a current product.
What we see here is basicly a 2011 design. The SE model had the SMPS replaced with a linear PSU and USB input added back in 2015, but was identical otherwise.
