Sweet! @johlju - I'll trade you: Can you review this one for me? It would be good to get this in after I complete the move to the new CI pipeline. #299

[johlju]

Yep, better to get thios one in after the module is converted.

@PlagueHO You could have re-targeted this PR against master instead of closing (where you edit the PR title). I open a new one since I can't re-open this one.

[PlagueHO]

I didn't actually close it - it closed automatically when the dev branch was deleted 😢

[PlagueHO]

Which is why I don't have a "reopen" button:

😁

[johlju]

Yep, need to re-target all PR's before removing the dev branch. 🙂 It's in the "Steps" 😉

[johlju]

No worries. But sad for those other PR's that might have been open, they won't know why it was closed. :/

[PlagueHO]

I'll go through and comment on them. I've already commented on the ones that weren't flagged as abandoned.

[PlagueHO]

Doh! Must have missed that step - I think I forgot where I was in the process a few times.
