## [0.18.0](https://www.npmjs.com/package/@alkdev/typebox/v/0.18.0)

Changes:

- Function `Type.Intersect(...)` is now implemented with `allOf` and constrained with `unevaluatedProperties` (draft `2019-09`)
- Function `Type.Dict(...)` has been deprecated and replaced with `Type.Record(...)`.
- Function `Type.Strict(...)` now includes the `$schema` property referencing the `2019-09` draft.

### Type.Intersect(...)

TypeBox now targets JSON schema draft `2019-09` for expressing `Type.Intersect(...)`. This is now expressed via `allOf` with additionalProperties constrained with `unevaluatedProperties`. Note that `unevaluatedProperties` is a feature of the `2019-09` specification.

### Type.Record(K, V)

TypeBox has deprecated `Type.Dict(...)` in favor of the more generic `Type.Record(...)`. Where as `Type.Dict(...)` was previously expressed with `additionalProperties: { ... }`, `Type.Record(...)` is expressed with `patternProperties` and supports both `string` and `number` indexer keys. Additionally, `Type.Record(...)` supports string union arguments. This is analogous to TypeScript's utility record type `Record<'a' | 'b' | 'c', T>`.

## [0.17.7](https://www.npmjs.com/package/@alkdev/typebox/v/0.17.7)
