Hash Tables usable on live?

[MateoSoetsu]

So I've been browsing the new hashtable feature in the beta and I was wondering, If I edit a map using the new beta editor will the map be playable on live? If I edit my map to use hashtables will it no longer be playable on live?

Also there has to be someone very knowledgeable and skilled to make a Hashtable Tutorial for GUI soon! I'd +rep that.
