Codeigniter project breaks with PHP 8

ok, I will update my CI4 version then. Thanks for the feedback guys

---

Hello, sorry to bother again. I was reading the documentation to update from version 4.0.4 (the one I have) to the latest one but am a bit confused on how it should be done (never upgraded versions before). Can you please help on the steps needed to upgrade? In the documentation they describe many changes but would not know how to implement them manually. Or should I just reinstall CI4 from scratch? Thanks

Basically, copy the changes from /vendor/codeigniter4/ to your project while keeping your own changes intact. The upgrade documentation should list the files that have been changed.
