And one more point.

In Valentina 2.0 engine we use our own system of testing.
We have HUGE number of tests (as teach Extreme Programming :-)
If I am not mistake the half of our sources -- are tests.

So I have very big hope that Valentina BETA will be quite stable.
And we will not need long time beta testing. Only to finish minor features
during that.

And this is latest result of testing from my computer

*************************************************************************
*                                FINISH
*************************************************************************
* Total  tests              : 9052
* Failed tests              : 59
* Failed tests on exception : 31
* Leaked tests              : 46

* Total  asserts            : 72661301
* Failed asserts            : 12
