Required version: 3.12 and above

A Few Words from the Author

• Upgrade. I recommend having two system instances: a production instance and a separate test instance. On the test instance, you can periodically refresh the database from the production system and run the upgrade there to make sure everything works, review new features, and identify anything that has stopped working for you.

• Move/delete third-party files, directories, and other items from the userside directory. It must contain only the distribution files of the system itself and files created by the system during operation. UserSide modules (usm) also must not be stored there. Use separate directories for them, for example `/opt/userside`. Third-party files in the userside directory may be deleted during the upgrade.

• Run the installer to upgrade the system:

sudo -u www-data php userside_install.phar install

• Do not forget to update all modules to their latest versions.
