Apple has just released iOS 10.3.2 to the public, following around a month and a half of beta testing that began shortly after iOS 10.3 came out. It's available as an over-the-air update or through iTunes for any devices that run iOS 10: the iPhone 5 and newer, the fourth-generation iPad and newer, the iPad Mini 2 and newer, both iPad Pros, and the sixth-generation iPod Touch.

Like the intervening iOS 10.3.1 update, the release notes for 10.3.2 only say that it "includes bug fixes and improves the security of your iPhone or iPad," which suggests that the release is primarily focused on security updates.

According to Apple's security update page, it fixes quite a wide range of bugs that affect everything from the iPhone 5 on up: one in the AVEVideoEncoder, one in CoreAudio, two in iBooks, one in IOSurface, two in the kernel, one Notifications bug, one in Safari, four SQLite bugs, one TextInput problem, a whopping eight WebKit-related fixes that address an even larger number of vulnerabilities, and an update to the certificate trust policy. As with any update that fixes a large number of bugs, you should patch as soon as you can to prevent exploits of the now-public vulnerabilities.
