Can't think of this is new but posted several times in developer preview forum and each comment has had new lines/line breaks removed so the posts are just continuous blocks of text.
To show what I mean, i started a new line for this sentence.
There should be a line space between this sentence and the previous one.
And 2 lines between this sentence and and the previous one.
If the line breaks show on this one I'm going to look stupid and feel confused...
