## [0.25.9](https://www.npmjs.com/package/@sinclair/typebox/v/0.25.9)

Updates:

- [282](https://github.com/sinclairzx81/typebox/pull/282) TypeBox now supports custom types. These types require the user to specify a custom `[Kind]` string on the type. Custom types can be registered via `Custom.Set('<Kind>', (value) => { ... })` which allow the TypeCompiler and Value API's to make use of user defined validation logic.
