STREAMTRADE There is just one bug reported on 2.9.1 and we have already provided a patch for that.
Of course, if there are any bug reports, we will fix that on 2.9.2, 2.9.3, and so on.
Till now, 2.9.2 is a sure thing, but you don't have to keep waiting, else you will never be able to update.
There will always be improvement and bug fixes. No software is perfect, there's always room for improvements.
