3.2.1 If you do not use use-package to configure Casual

Before installing Casual, you should update all of your existing Casual packages. This is most easily done via the package menu buffer ((emacs)Package Menu) . After updating your packages, install the casual package.

Migrate your existing Casual packages from 1.x to 2.x by running the following commands:

M-x load-library casual
M-x casual-upgrade-base-to-version-2

Any Casual v1.x packages that have been superseded by this package will be uninstalled.

While not necessary, it is recommended to run M-x package-autoremove to purge any dangling dependent packages. Cautious readers can choose to audit any packages that are targeted to be removed.
