Deprecating an entire component
The duration and schedule for deprecating an entire component maps directly to the duration associated with the highest API tier of an API exposed by that component. For example, a component that surfaced APIs with tier 1 and 2 could not be removed until the tier 1 deprecation schedule was met.
| API tier | Duration |
|---|---|
Tier 1 |
Stable within a major release. They may be deprecated within a major release, but they will not be removed until a subsequent major release. |
Tier 2 |
9 months or 3 releases from the announcement of deprecation, whichever is longer. |
Tier 3 |
See the component-specific schedule. |
Tier 4 |
None. No compatibility is guaranteed. |
