What is Drupal's End-of-life phase? Drupal's End-of-life (EOL) phase is the period of time when a particular version of Drupal will no longer be supported by its developers. After this period, all bug fixes and security updates will cease to be provided. This means that if you do not upgrade your website before the EOL phase, you risk security vulnerabilities and other potential issues. For instance, if your current website is running on Drupal 8, the EOL phase for this version is November 2021. This means that you must upgrade your website to either Drupal 9 or 10 before November 2021 in order to keep receiving bug fixes and security updates. Otherwise, your website will be left vulnerable to malicious attacks. Therefore, it is important to be aware of the EOL phase for your current Drupal version in order to take timely action and avoid potential risks.
