Back in September, when Apple was releasing new software on a semi-regular basis, the company also released updates to older versions of both iOS and watchOS.

And now the company is following up with another update for the latter. Apple on Wednesday officially released a new version of watchOS 5.3.2, this one specifically meant for the Apple Watch Series 4. The update is meant for owners of older iPhone models that cannot update to iOS 13, which means they will be able to continue to use their Apple Watch Series 4 with the older iPhone.

Apple’s original release of watchOS 5.3.2 was meant for the Apple Watch Series 1, Series 2, and Series 3.

Some Apple Watch Series models are able to upgrade to watchOS 6, which his the latest version of the smartwatch operating system to date. However, to run that software you need an iPhone that can also run iOS 13. That is a pretty lengthy list, sure, but some iPhone owners have decided to hold onto their aging handsets rather than upgrade.

If you own an iPhone 5s or iPhone 5c, for instance, you can’t get an official update to iOS 13. As such, Apple released iOS 12.4.2 for those handsets, and others. With both iOS 12.4.2 and watchOS 5.3.2 installed on the devices, owners should still be able to keep using their iPhone and Apple Watch pair without any major issues.

The updates include performance improvements, as well as bug fixes. watchOS 5.3.2 is available now for the Apple Watch Series 4.
