Keeping your WordPress installation up to date is a mandatory if you would like to preserve your website bugfree and also secured with the most recent security fixes and updates from the WordPress team.
When a new update is available you will be usually informed for it at the dashboard of your WordPress admin area.
It is important that before you perform the actual update of your WordPress platform you ensure that a full backup of the current web-site is performed. If you are not quite sure how this can be achieved please check our Backing up your website manually tutorial.
The first and most probably the easiest way is to use the provided update tool in your WordPress admin area. In order to access the web interface of the update too you will need to navigate to Dashboard->Updates.
At that page you will be presented with the available updates for your WordPress platform and also for the Plugins and Themes your website is using.
In order for the update process to be initiated you will need to click on the Update Now button. Once you do that you will be redirected to the page where information regarding the update process will be presented and once the update is finished you will be redirected to the Dashboard of your WordPress admin area with a successful update message.
The second and a bit harder way is to manually perform the update of the platform by replacing all of the current files of your WordPress installation with the files for the new version of the platform. Bellow we will outline the process in points.
