We’ve talked about the end of life of Drupal 8 since it was first announced, and now it is actually here. If your current website still runs on Drupal 8, there is no better time than now to make the upgrade.
What does end of life mean?
Fortunately, it does not mean everything will stop working all of a sudden. However, it will only be a matter of time before something goes wrong. This is because once the end of life is reached, the community no longer maintains the code, bugs are not fixed, vulnerabilities are not identified or removed, compatibility is not updated.
