I know the team worked hard, but to be honest I have not spotted anything that has improved. Perhaps under the hood, but not my user experience. (based on about 7 days experience)
For example . . . all settings are deleted during the install and it just took me 15 minutes to not find the Auto Browser Cleaning setting. Seems it has been removed.
And there are many other examples. i am sorry to see my beloved ccleaner has taken a wrong turn on the road to the future
