Description

This is an umbrella for tracking planed breaking changes that are targeting for the next major version bump.

Please be aware that, in order for the breaking changes to be included in the next major version bump, the following preparations need to be done in advance:

• The old APIs need to be deprecated, 2 minor releases before the major version bump for @Public APIs, and 1 minor release for @PublicEvolving APIs

• All internal usages of the deprecated APIs should be either migrated to replacing new APIs (if any) or deprecated / removed. This ensure that we can quickly remove the APIs during major version bump without need for extra migration efforts.
