Today is the second Tuesday of the month, which means that it's Patch Tuesday, the day that Microsoft releases new updates for all supported versions of Windows. This month, every version of Windows 10 for PCs got cumulative updates, and even supported versions of Windows 10 Mobile got updates as well.
Of course, it's not uncommon for Windows 10 Mobile to be updated in parallel with PCs, but that hasn't been the case over the last couple of months.
PCs on the Windows 10 Fall Creators Update, or version 1709, will receive KB4093112, which brings the version number to 16299.371 and can be manually downloaded here. Here's what got fixed:

There's also one known issue to be aware of:
| Symptom | Workaround |
|---|---|
| Windows Update History reports that KB4054517 failed to install because of error 0x80070643. |
Even though the update was successfully installed, Windows Update incorrectly reports that the update failed to install. To verify the installation, select Check for Updates to confirm that there are no additional updates available. You can also type About your PC in the search box on your taskbar to confirm that your device is using the expected OS build. Microsoft is working on a resolution and will provide an update in an upcoming release. |
Windows 10 Mobile devices never actually got an update to Redstone 3, so they're not on build 16299. Instead, they'll be getting the latest feature2 cumulative update, which is build 15254.369, and that includes the same fixes and improvements as today's update for version 1703.

If your PC is somehow still on Windows 10 version 1511, you'll see KB4093109, and the build number will be 10586.1540. This update is not available for phones, as Windows 10 Mobile version 1511 is unsupported. You can manually download the update here, and it contains the following fixes:

While the changelog for the 1511 update was modest, PCs still on the original version of Windows 10 got a longer list of changes. Those devices will see KB4093111, which brings the build number to 10240.17831, and can be manually downloaded here. Here's what's fixed:

NlpVerifyAllowedToAuthenticate: AuthzAccessCheck failed for A2ATo 0x5. This can be due to the lack of claims and compound support in NTLM

Obviously, you shouldn't need to manually install any of these updates, unless you're actively trying to block your machine from installing a newer version of Windows 10. You should be able to go to Settings -> Update & security -> Windows Update -> Check for updates, and the service will download the cumulative update that's appropriate for your machine.
