In the most recent release notes on contextgarden it is said:
	"This was the first version that separates between a 'mark ii' and  
'mark iv' version."
I guess I missed something important, but I am ignorant on the terms  
"mark ii" and "mark iv" version.
Searching contextgarden did not reveal an explanation to me.
I would appreciate if someone can point me to some reading stuff.
