You can check for a new version at any time via Help->Check for Updates, just like you could in previous versions.

Server updates will still require going to the Updates page.

In-product updates are only available on Pro.

Doing so will complete the update process by replacing the current version of Pro with the new one.

Once downloaded, you will be prompted to install the update and relaunch Pro. Unlike the previous versions of Pro where you would be taken to the Updates web page, the new version will be downloaded all within Pro itself. You can elect to either install it, be reminded later or skip the version entirely. If there's a new minor version available, you will be asked when you open FileMaker Pro if you'd like to install the update. With these changes FileMaker has modernized the updating process, which should ultimately result in more users on the latest version, a goal that aligns with FMI's continued focus on security.

But that's not all - the updaters are significantly smaller in size, making downloads faster. FileMaker 15 introduced a much welcomed improvement to the updating process: you can now upgrade your FileMaker Pro directly in Pro itself, instead of needing to hunt for an updater on a separate web page.
