Updating Modules

Most contributed modules will receive periodic updates that fix security issues, fix issues with the module's functionality, add new features, or all three. It's a good idea to regularly check for new versions of the module's you're using and update them when newer versions are released.

The process of updating a module is very well described in the User Guide - read chapter 13.6: "Updating A Module".

If you are using Composer to manage your site, read 3.5. Using Composer to Download and Update Files.
