api versioning strategy, when to break things?

hey folks, im grappling with api versioning lately. were at a point where we need to make some breaking changes to our core api, and im weighing the pros and cons of different versioning strategies. url path versioning like v1, v2, header versioning, and query parameter versioning. what are your experiences? when did you decide it was time to introduce a new major version, and what was your rollout strategy to minimize disruption for existing users? im looking for practical advice here.
