Re: Changing the output of tooling between majors

As Eric said, a major release is not a license to make externally visible breaking changes. We are too mature a project now. I have OCD tendencies like many people here, but one must learn to live with aesthetically imperfect tool output. Internal changes are fine, external changes that are act

Re: Changing the output of tooling between majors

This adds maintenance overhead but is a potential alternative. I would only flip the flag. I would prefer to make the default "legacy" output and innovate behind a "--output-format=v2" flag. That way tools do not break or have to change to pass in the new flag. Ideally we should always version

Changing the output of tooling between majors

Hi list, I want to clarify the policy we have when we want to / going to change the output of the tooling (nodetool or tools/bin etc.). I am not sure it is written somewhere explicitly, but how I get it from the gossip over years is that we should not change the output (e.g. changing the name
