Symfony 5.0.0 is going to be released in a few days. It contains all new features from 4.4. But for the first time ever, Symfony 5.0.0 will come with new components that are marked as experimental:
- String, a component for object-oriented strings management with an abstract unit system (nicolas-grekas, hhamon, gharlan) #33553
- Notifier, a component that sends notifications via one or more channels (email, SMS, ...) (fabpot) #33687
