If you installed IntelliJ IDEA using the Toolbox App, it will suggest you to update the IDE when a new version is available. In this case, you have to download new versions of the IDE and install them manually as described in Standalone installation. If IntelliJ IDEA does not have HTTP access outside your local network, it will not be able to check for updates and apply patches.

To open this tab manually, select Help | What's New in IntelliJ IDEA. When IntelliJ IDEA updates to a new major release, it opens the What's New in IntelliJ IDEA tab in the editor with information about the changes, improvements, and fixes. However, sometimes patch updates are not available, and a new version of IntelliJ IDEA must be installed. Updates are usually patch-based: they are applied to the existing installation and only require you to restart the IDE. By default, IntelliJ IDEA is configured to check for updates automatically and notify you when a new version is available.
