I might be wrong but I had the impression that stability declined starting with Q9
The user base on this forum grows every day, and they keep selling more new AX8's every day, with many new users. It is entirely logical that there is no decline in stability, but instead just a larger number of users, and when you have more total users, you can see more reports of possible issues, even if the total instances are proportionally less than ever.
If you have 100 people use something and 1% report a problem in 6 months, we see 1 thread about an issue. If we have 10,00 users and 1% of users report an issue, we would see 100 users complaints and think there is suddenly a big issue as now it seems 'everyone' is posting about issues
