where can find v11.9.1 configuration manual

[gd123294813]

Hello, everyone!
where can find v11.9.1 configuration manual.
I have a switch that doesn't work in the v12 environment, but it works fine in the v11 environment.

in v11 MEPLHAA script:
{"c":{"o":0,"l":2,"i":0},"a":[{"0":{"r":[{"g":4,"v":0}]},"1":{"r":[{"g":4,"v":1}]},"t":1,"b":[{"g":12,"t":1,"i":0}],"s":0}]}

in v12 MEPLHAA script:
{"c":{"io":[[[4],2],[[12],6]],"l":2},"a":["t": 1,{"0":{"r":[[4]]},"1":{"r":[[4,1]]},"b":[[12],[12,0]]}]}
The fault symptom:
the switch button can‘t work.

So I want to read the version 11 configuration instructions about MEPLHAA Script, but I can't find any information about the configuration instructions except for the firmware for version 11.

The current version in use: https://github.com/RavenSystem/haa/releases/tag/11.9.1
