Is composer update enough for CodeIgniter upgrade?

I am in the process of updating my CodeIgniter framework from version 4.1.3 to 4.1.4. The process requires me to update incrementally, step by step for each version. I initially attempted to use the "composer update" command, however, it only updated the libraries and not the framework itself. As a result, I am searching for a solution to effectively update the framework to the latest version.

If composer update does not update the framework, you installed CI4 manually.
