Hi guys,

First of all I am sorry, but I was a really busy with other things in the past year.
I didn't have enough free time to keep track on CFO related stuffs.

Now, It seems that I can spend more time on CFO. I can't make big promises.
I still don't get too much time for this, but I hope it will be enough to fix those
bugs and the regressions.

If it is OK for you I will on this topic.
