Let's see how to update your Drupal site between 8.x.x minor and patch versions. For example, from 8.1.2 to 8.1.3, or from 8.3.5 to 8.4.0. I hope this will help you.
If you are upgrading to Drupal version x.y.z
x -> is known as the major version number
y -> is known as the minor version number
z -> is known as the patch version number.rajamohamed Sat, 03/24/2018 - 10:31
