As a website owner, you should at the very least login to your WordPress website once a month. When you do you will notice some highlighted messages that say that there is a new version of WordPress and to update now. Also you might see notation on plugins that should be updated as well as themes.
Yes! Once a month visit your website and do some updating. It is important to update the WordPress core because the developers who work on WordPress are constantly improving the system and patching up vulnerabilities. The same goes for plugins and themes.
I find that a lot of WordPress website owners neglect their websites. Months sometimes years have gone by without logging in and cleaning house. The problem here is that the longer you wait for updates the more susceptible your site is for hacking. Also, longer spans between WordPress versions can mess up a website when updated. You will also find that over a long period of time some plugins will stop working or be in conflict. It is best, in this case to backup your data and files before doing and update. If all goes well, great. If the site breaks then it will be necessary to install a new version of WordPress and then import the data and files to the new installation.
