Design Documents for Supported Features

Supported proposals describe extensions implemented and released as fully supported features of the library. A fully supported feature has a high-quality implementation. If the proposal impacted the public API of the library, it should have provided updates to a publicly available documentation about the library, including internal documentation if necessary. A fully supported feature is regularly tested.

Proposals that appear in rfcs/supported may be retained indefinitely to provide insight into the design of existing features.
