Hello

Is it normal that FAC 6.6.9 has more known issues that 6.6.8, which in turn has more known issues thank 6.6.7, which in turn has more known issues than 6.6.6?

From what I understand, normally each new patch should fix known issued from the previous version, right?

That is a good question. But the thing is that when a software version is released, it does not come out with a list of bugs. They are found along the way. 
When 6.6.6 comes out, it inherits some known bugs that are still being fixed and new ones that were found very close to or when this version was locked for release.
The same goes for 6.6.7. Inherited bugs from 6.6.6, and also the list is being updated as some unknown bugs were found to exist. on those versions.
At the end, there are multiple bugs fixed from one version to the other, but there might also be others found and ready to be fixed.
Seeing the list means that the product is being heavily tested and always improving. :)
