CodeIgniter v4.0.3 released

Thank you Lonnie and framework and user guide dev. team! Working with CI4 has been great so far!
but, I'm new here, how do I update version 4.0.2 to the latest version 4.0.3, is there anyone who can help me, because I'm working on my project in the previous version now.

If you are using composer (if not you definitely should) all you have to do is to execute command: "composer update" and that's it!
