Background/Context

This ADR is a response to the approval of RFC 0003-folio-breaking-changes. This RFC was the product of the FOLIO Technical Council Subgroup on Breaking Changes.

Assumptions

That a breaking change, and its impact on versioning, is understood within the definitions laid out by semantic versioning practices.

Constraints

N/a

Rationale

The FOLIO Technical Council Subgroup on Breaking Changes was charged with determining the appropriate mechanisms for communicating breaking changes during the development and release processes.

In discussing this issue, it became apparent that a shared understanding of what does or does not constitute a breaking change, within the context of FOLIO development, was needed in order to provide further guidance on the topic.

Decision

The determination that any change is or is not breaking should be consistent with the guidelines laid out in the 0003-folio-breaking-changes RFC

Implications

Pros
- Development, devops, operations, and release management professionals contributing to the FOLIO project can utilize a common understanding of what does or does not constitute a breaking change.
Cons
- Some practices currently in effect may be inconsistent with the guidance laid out in RFC 0003-folio-breaking-changes. These practices will need to change, and there may be a switching cost to this change.
