Is iPad Mini 2 still getting software updates?

Sorry, but no, with the exception is point updates ( security updates ) under iOS 12.

iOS just got another point/security update to iOS 12.4.9.

Still quite an array of third party apps still supporting iOS 11 and 12, so I wouldn't worry too much, just yet.

Best of Luck to You!

A first generation iPad Air can only be updated to iOS 12.4.9.

Apple ended major update support for iPad mini2 in September 2019, however, security “point” updates have since continued - the most recent being released a few days ago. An iPad Mini2 cannot be updated to iPadOS 13 (or any later major versions of iPadOS) as the internal hardware does not meet the minimum technical requirements (CPU and RAM) for newer versions of iOS/iPadOS.

Some App developers have dropped support for iOS versions preceding iOS 13.x for technical reasons (often because APIs or software libraries upon which they rely have been updated in the new version of iPadOS, making their App incompatible with earlier versions). 

Whilst many App titles remain compatible with your iPad mini2, if you want or need to access to Apps requiring the most recent versions of iOS, you’ll need to consider replacement of your iPad with a newer or current model that supports iPadOS13/14.

I hope this information provides helpful clarity as to your available options - and the limitations of your existing iPad.

No, not beyond Last: iOS 12.4.9
