How do I update a module manually?
Updating a module is usually two steps:


Replace the files with the new version you downloaded, for example via FTP.
Run update.php (it is not always needed, but run it to check if updates are needed).


When updating, it can be a good idea to try the update on a local development environment to check that nothing breaks, and do a backup before the live update. Some updates are minor and won't need this.

Views, which stores a lot of configuration in the database and has recently undergone major changes, is one of those modules where you usually want to test it out before upgrading.
