Thanks for the info - I understand with open source projects resources are often limited, however I would like to point out that the release notes for 3.18.1 link to the upgrade docs, not the update docs you pointed me to.
I’m not sure where the update docs are linked from, however I think the best thing would be if they’re added to the overall manual. I’ll have a look and see if there’s some way I can contribute or suggest that approach.
Cheers, Steve
