What happens when a newer version of CodeIgniter framework is released?

Two things happen, independently. First, the generated app is Composer-based, so you can update the CI4 framework yourself at any time with `composer update codeigniter4/framework` without waiting for a CI Wiz release. The generated code uses standard CI4 patterns, so minor and patch version updates typically require no changes to your app code. Second, once a new CI4 version is verified stable, Ozar updates CI Wiz to use it as the base for newly generated projects. The key word is "verified stable" — CI4 ships release candidates and patch releases regularly, and not every one gets immediately incorporated. The goal is that CI Wiz always generates against a known-good CI4 version, not whatever landed in the repo yesterday.
