M language and SSAS commands - reference materials and documentation

[Stachu]

Does anyone know where I can find documentation on cube commands in M language? I work with SSAS cubes.

I only found that website - https://msdn.microsoft.com/en-us/library/mt211003.aspx, and there is no documentation on e.g.

Cube.AddAndExpandDimensionColumn

Cube.Transform

Cube.AddMeasureColumn

Google also doesn't help

basically I need something similar to that:

but I cannot find latest version anywhere - can someone help please?

EDIT: it seems August 2015 is the latest version. Any plans to update it?
