Which Mortis Dreadnought rules?

[hyudun]

Trying to figure out which rules are most recent and valid for the Mortis Dreadnought (not to be confused with the Contemptor-Mortis) in non-apocalypse games.

In the left corner, we have this PDF from Forgeworld - http://www.forgeworld.co.uk/Downloads/Product/PDF/s/Smupdate.pdf
In the right corner, we have the entry in Imperial Armour Volume Two - Second Edition.
I have no clue what the publications dates on either of them are.
There may even be 3rd - Nth challengers I'm not even aware of!

The points cost ARE different, as are the rules and what armies they can be taken in.

So, everyone, which rules entry trumps all others?

I think the most up to date 40k rules can be found in IMPERIAL ARMOUR VOLUME TWO SECOND EDITION - WAR MACHINES OF THE ADEPTUS ASTARTES.

Upgrades wise it works out better in this book as well :)

The base 10 points increase gives you the helical targeting array for free and the weapon options are cheaper.

I like the 30k version better. BS5 and cheaper, however it cannot take the back mounted missle launcher.

You do of course have to be playing a 30k list to use it though, or unbound.
