How to downgrade ?

Maybe you could read this, Issue #3953

Please stop suggesting downgrading on every other issue (not calling names, not suggesting that you do that, but as while collective), it generates a lot of noise for subscribers.
This issue, and many others, specifically target latest release and issues within that release. Reverting back to other version makes no sense here and does not help fixing those issues.

I don't want to downgrade, but I have no choice because the issue still exists after 10 versions have passed
