If you are not using a package manager such as homebrew to manage your odd-box installation, you can either manually download new versions from the github release section or use the built in command for doing the same: odd-box --update
odd-box --update
Note: Should you have an older configuration file than V2, you can upgrade it automatically thru the odd-box --upgrade-config ./my-config-file.toml.
odd-box --upgrade-config ./my-config-file.toml
