It also contains a number of HomePod-related fixes:

There are also a long list of security fixes for a wide array of vulnerabilities, ranging from a Bluetooth issue that could be leveraged to execute arbitrary code, to a FaceTime bug that could allow an attacker to trigger FaceTime calls on remote iPhones and iPads.
The recommended way is to tap Settings > General > Software Update and carry out the update from there. You will need Wi-Fi access and your battery to be charged above 50 percent, or the device will need to be connected to a charger (although I recommend that devices are connected to a charger during the update process no matter what the battery charge level).
Alternatively, if you have Automatic Updates enabled (you can find this setting in Settings > General > Software Update) then you can just wait for it to come in when it’s ready.
Or, if you like doing things the long, hard way, you can connect the iPhone to a PC or Mac running iTunes and do the upgrade from there (keep in mind that this makes the download much bigger).
