Lgtm, except for the massive amount of unrelated whitespace changes.
This makes review very hard and also seeing the real change later when browsing the history.
Could you consider reverting all the unrelated whitespace changes and maybe reformat the whole codebase with the settings you want to have within an own commit?

[leonard84]

Yeah didn't notice the whitespace change, I really need to make the reformat commit for the whole codebase.

Lgtm, except for the massive amount of unrelated whitespace changes.

Maybe this helps, if something like this happens again unintentionally:

@leonard84 Any estimations when this fix will be released?
