Stepper.Setup syntax error on 1.53.3

[Electroguard]

Normally my policy is "if it aint broke, leave it alone".
But was eager to upgrade to 1.53.3 for the wonderful new interface benefits.
Unfortunately, when testing after, it stops with a syntax error at STEPPER.SETUP
I tried just omitting the channel number (which was the original problem), but it wasn't that.
This was its first firmware upgrade since the multi-channel STEPPER.SETUP was fixed, so I don't know whether the problem has crept in with this latest 1.53.3, or perhaps snuck in previously.

The stepper is not included by default in the firmware.
You must use a version that includes STP in the name

edit: I just updated the 1.53.4 with the STP

Thanks again.
