I just received this message from Apple. They've clearly flagged me as a member of the Retro-Rebellion!

Dear Daniel,
On 30 June 2018, Apple will implement changes to continue to ensure your financial data is protected when you make purchases on the iTunes Store or App Store.
Our records show that you may be accessing the store from an older version of iOS, macOS or Apple TV software:
iOS 4.3.5 or earlier
macOS 10.8.5 or earlier
Apple TV Software 4.4.4 or earlier
To be able to change your payment information with devices running the software listed above, you'll need to update to a more recent software version.
Learn More.
Regards,
iTunes Support Team

So, we won't be able to update our credit card details on a pre-Mountain Lion Mac? This would be the first time Apple have ever notified me of feature loss due to running older software. Normally things just silently stop working. How thoughtful. Thanks Apple!
