For details see:

In July 2018, 'squid 4' was "released for production use", see:
https://wiki.squid-cache.org/Squid-4
"The features have been set and large code changes are reserved for later versions."
I've tested almost all 4.x-versions and patch series before with good results.
Right now, 4.4 is running here with no seen problems together with
'squidclamav', 'squidguard' and 'privoxy'.
I too would declare this version stable.
Best,
Matthias
