It seems that the new Wiki interprets a line-feed as beginning of a new paragraph. Before only two LFs where interpreted as paragraph separators. I liked the former interpretation because it allowed to split a paragraph into lines, where each sentence or each part of a sentence is on an individual line. This is better for all the line-oriented Diff-tools. Also code like <haskell> class C a where method :: a instance C Int where method = bla </haskell> is formatted with strange indentation as class C a where method :: a instance C Int where method = bla
