Is it possible to have some examples of the commit message format? I see you use "style/XXX" where XX is changed file or module. I am not sure if this is what is missing, sorry for any miscommunication here. I Will also dig more into gitcop to see what I can find.

This PR will not pass tests until the 0.2 code commit lands AFAIK.

I see you have figured it out, but you are right, having an example in the guidelines would certainly be nice (issue #48).

Since I saw that #46 passed with the other changes I will go ahead and merge it even though it's failing.

Thanks you! :)

Oh 😮, only the PR title had the correct format, not the commit. Oh well...

[dirvine]

Ah yes I spotted that just after the merge. Oh well not to worry. Sorry chap, I ended up rebasing (hard) locally and could not get back to the commit. At least I now know. Next time though it will all be good.

[hobofan]

Yup, better luck next time :)
