Thanks @mateuszmalek - just a couple minor things to address below. Could you also add a test for the new version number (or update the test for 7.4 with 8.2?)

Thanks!

@jackofallops I've made adjustments according to your feedback.
I've also added test for 8.1 (which was missing) as well as introduced 8.2.
