It has been more than a year since Apple discontinued the AirPort router lineup, but the company has just released an important security update anyway.

Apple on Thursday officially released a new update for the AirPort Express, AirPort Extreme, and AirPort Time Capsule. The new software is version 7.8.1 and it “improves the security of your base station”. The company says the software update is recommended for all Apple 802.11n Wi-Fi base stations.

Firmware update 7.8.1 improves the security of your base station and is recommended for all Apple 802.11n Wi-Fi base stations including AirPort Express, AirPort Extreme and AirPort Time Capsule.

As is par for the course, Apple isn’t providing many details about the update itself. However, considering the security focus, it might be a good idea if you’re still using an AirPort Express, AirPort Extreme, or AirPort Time Capsule to update your hardware as soon as you’re able.

Apple is planning on releasing updates for the cancelled AirPort lineup of routers for the next four years or so, after initially promising updates for five years after the discontinuation. So it’s likely this won’t be the last firmware update we see for the lineup.

Are you still using any AirPort routers?
