Question about version attribute on Diebox in CoreRPG

[huntsfromshadow]

For the fun of it, I decided to look through CoreRPG's ruleset to understand it.

I hit something I can't find a good answer for.

In the gameelements.xml I find two definitions for diebox.

<diebox version="&gt;=4">
		<frame name="diebox" offset="9,4,9,4" />
		<font expression="diceexpr" total="diemod" dieresult="dieresult"/>
		<icons secret="gmdieicon" defaultdie="die_general_icon" />
	</diebox>
	
<diebox version="&lt;4">
		<frame name="diebox" />
		<margin value="16" numbertailmargin="10" />
		<secreticon name="gmdie" />
	</diebox>

I can pretty much guess the version attribute is controlling which one is loaded.
(Confirmed by me futzing with the code).
My question is what is version 4? Is that Unity?

V4 is Unity.

Cool.
Thank you nice to confirm that.
