Could we explicitly list in changeset which field-types and which arguments are impacted, preferably between the 1st and 2nd paragraphs. I know that CalendarDay - { format } changes, and presumably there's a few other cases that we should call out so that devs can easily scan their code for places they might need to change things.

[Vultraz]

Done.

[timleslie]

Righto, have looked through all the code and I think it's all 👍

The only remaining change I think we should make is that all the changesets should be major. If someone does a patch update of the list-plugins package for example, it will possibly break if they haven't also updated their fields package.

[Vultraz]

Also done.

[timleslie]

Looking good 👍
