Well, that is easy - just read what the changes are about.
Last week many PoW networks saw a big loss in hashrate, because the China firewall started blocking dns resolition and mining traffic towards mining pools. This update handles exactly that messy situation by allowing to mine on behind the fw (use tls enabled and --dns-over-https 2). Because the update mainly addresses problems in China I tried to welcome them more by doing the change log in Chinese one single time

Ok pretty dev xD
Yes I thank the Chinese firewall, it allowed us to do more blocking solo

Yes we saw the drop in hashrate suddenly after I have been using the devil's DNS since the beginning as we call it in our country because it encrypts all even the illicitly illegal content ...
In hiveos, it's very practical and cloudflare manages that very well
The hashrate has come back quite fast... I think they search for solutions to avoid that.
