Red is versioned as major.minor.micro
While this is very similar to SemVer, we have our own set of guarantees.
Major versions are for project wide rewrites and are not expected in the foreseeable future.
Anything in the redbot.core module or any of its submodules which is not private (even if not documented) should not break without notice.
Anything in the redbot.cogs module or any of it's submodules is specifically excluded from being guaranteed.
If you would like something in here to be guaranteed, open an issue making a case for it to be moved.
Breaking changes in Red will be noted in the changelog with a special section.
Breaking changes may only occur on a minor or major version bump.
A change not covered by our guarantees may not be considered breaking for these purposes, while still being documented as a breaking change in internal documentation for the purposes of other internal APIs.
