codeigniter v4 rc for upcomming project

Kiranrs I think he just meant that the system folder will update itself automatically (via Composer) or can be swapped out entirely (via manual install) but changes in the framework to anything in app/ require you to make those changes yourself. For example there was a bug fixed recently where the Email config didn't extend BaseConfig (https://github.com/codeigniter4/CodeIgni...2776bf02ae). This means that anyone who installs via the current Release Candidate will need to make that change to their application manually in order for it to work with the core moving forward.
