【Encountered Issues: Problem Phenomenon and Impact】
I don’t know which version everyone is using. I see that the newer version is 6.5.5, but I’m hesitant to use version 7.0.
LTS versions are all fine. If you want more stability, I recommend 6.1.X and 6.5.X.
I am currently using version 6.5.3, I can try 6.5.5.
6.5.5, the larger the last number, the fewer issues with this major version.
This year, version 7.5 LTS will be released. If you are in a hurry, use 6.5.5 first; otherwise, wait a bit longer.
6.5.x or 6.1.x maximum subversion
I recommend the latest version 6.5.
Personally, I think it’s better to go directly to v7.1.1. After all, we will eventually need to upgrade to version 7, and applying for a major version upgrade is relatively difficult.
The BMW 7 Series is not well-received.
Wait a few days to upgrade to 7.1.2.
You can upgrade to V6.5. After we upgraded to 6.5, it became much more stable than before.
What was the original value? Explain in detail where it is unstable.
What was the original version?
Today you ignore me, but tomorrow you’ll find me out of your league, hohoho~ 
I’ve been waiting for a long time, and version 6.5.6 still hasn’t been officially released.
There is a 4.0.13 version, it’s too old.
It seems that 6.5.5 is still the most common.
