As new capabilities are developed, the Portsdown evolves through major changes to take advantages of updates to the operating system and features. Older versions cease to be updated, but unlike "Windows" they don't stop working. Just tighten the screws in the lid, don't connect them to the internet and keep putting them on the air!

Portsdown 2020 is based on the RPi Buster operating system. There is no routine software update available from Portsdown 2019, which was based on the older Stretch operating system, but you can build (or buy from the BATC shop) a new SD Card and simply fit it in place of the old card to get the new features.
