Version updates of CMS websites and PHP or updates to the database engine are collected under the generic term "updates".
Updates are required to close security-related gaps in the versioning of a CMS (Content Management System). This in turn prevents hackers from taking over a web application – and possible legal and financial consequences that arise, among other things, if the attack was identified too late and therefore not acted upon quickly enough.
With PHP or database updates, the update aims to improve (technical) functionalities of PHP versions, JavaScript libraries, TypeScript etc. as well as the connected databases and their management systems (MySQL, PostgreSQL, MariaDB, SQLite, Oracle Database, etc.) to ensure. When it comes to maintenance, on the other hand, the update refers to the content, i.e. texts and haptics.
