Re: Documentation Updating...

Hello,

I would use the approach 3b. This seems to be the best solution for me since 
it shows clearly when a member is present without those <since> <removed> 
<again-since> <removed again> tags. In addition it would be similar to the 
way microsoft has it's documentation organized. Each Member in MSDocs has 
a "Available in:" note on the bottom.

But is this checking if a member can be removed or not necessary? In my 
opinion marking the member with short <avaliable_in> tags would be enough.

Kind Regards,
Valentin S.
