Ya...they fixed the glitches.
They fixed some of the glitches.
Some of them. There's several important ones (quad core support especially - bug
introduced in version 1.1) that they never fixed.
I don't know what QA means but I do know that they should have been able to fix all the glitches by now....
QA = Quality Assurance = Testing.
Also, why should they have been able to fix all the glitches by now? Because you say so? Well, I say you're wrong. And having actually done coding myself, I can state that hunting down bugs is a difficult and time consuming process.
