I wanted to upgrade my Mosaico extension to the latest version. There was no upgrade link on the extensions screen so I downloaded the latest release and replaced the source files. However, the version number is still corresponding to the previous files. Do I need to do anything else to notify Civi that the files have been updated? I know in Drupal you would normally run the database update, but I don't know if there is something similar in CiviCRM? I couldn't find any documentation on a manual upgrade process.
I am running CiviCRM version 4.7.28.
