I don't want to release something that turns out not to work correctly, when I know that all I needed was some extra time in order to fix it. I also don't want to find myself in a situation where we go "ups" forgot add this and that.
Usually developers have a tendency to not say anything if there is a delay but I honestly prefer to let you all know now before you start wondering by tomorrow where the update is.
This means that the update is postponed and will be available as of Sunday 20.00 GMT +2.
Thanks for your patience.
