LGTM

We will probably release a major version for the aragonCLI cause we introduced a breaking change making ipfs optional.

We could also release a minor only with the PRs for updating apm publish.

[0xGabi]

aragon apm publish now needs confirmation so I included the --skip-confirmation flag to skip confirmation.

@sohkai What do you think about propagate content. Is this something we want to do as default on each publish? There is a new flag: --propagate-content that we might want to configure as well.

[sohkai]

@0xGabi Having that flag would be useful too, although if it prompts users by default, I think that's fine as well.

[0xGabi]

Oh ok, I thought it might break the CI. But I just realize that all checks have pass 😅

Will revert last commit then.

[sohkai]

Ah, we don't publish from the CI 😄

@sohkai Ready 👍
