When a new version of Word Press is available you will receive an update message in your Word Press Admin Screens.
To update Word Press, click the link in this message.
WARNING: The upgrade process will affect all files and folders included in the main Word Press installation.
This includes all the core files used to run Word Press.
You should do this as soon as possible after step 1. If you have caching enabled, clear the cache at this point so the changes will go live immediately.
You should make sure that you only copy the files from inside this directory, rather than replacing your entire wp-content directory.This is where your themes and plugins live, so you will want to keep them.If you have customized the default or classic themes without renaming them, make sure not to overwrite those files, otherwise you will lose your changes.(You’ll still need to click “Update Now” for major feature releases.) See Also: Configuring Automatic Background Updates Modern versions of Word Press let you update with the click of a button.(This feature was added in 2.7, so if you are using an older version, you will need to follow the steps to update manually.) You can launch the update by clicking the link in the new version banner (if it's there) or by going to the Dashboard Updates screen.
