This is a recommended update for anyone using WordPress as it addresses several security issues.
Anyone who has my monthly maintenance package has already been updated. If you are responsible for updating your own site and you use WordPress, please check to make sure you are updated.
Remember to back up your site and before you attempt the upgrade, and if you have any site customizations make sure that they are compatible with the new version before migrating!
Keeping your site updated is important for security. It also makes the internet a safer place for you and your readers.
