As WordPress is constantly being developed, it's important to keep yourself up to date with the software community's latest activities.
If you visit the dashboard of your own WordPress site regularly, you'll be able to stay up-to-date with WordPress news and software releases. There are widgets on the dashboard that display the latest news and announcements, and an alert always appears when there is a new version of WordPress available for download and installation.
If you prefer to visit the website, then the most important spot to visit or subscribe to is WordPress Releases. Whenever there is a new release, be it a major release, or an interim bug fix, or an upgrade, it will be at https://wordpress.org/news/category/releases/.
