Newest change November 3, 2026

## 7.0.0

6 breaking changes, first published November 3, 2026.

- **Removed** `TypeCompiler.Compile`  

TypeCompiler.Compile is gone. Import Compile from typebox/compile instead. [github.com](https://github.com/react-hook-form/resolvers/releases/tag/v7.0.0)
- **Behavior changed**  

TypeBox's single required error is now one error per missing field, localized through the active TypeBox locale. Code that expects a single required error must handle several. [github.com](https://github.com/react-hook-form/resolvers/commit/0d4a3d24cf2caace3f42b371298a6594e79ddfb4)
- **Behavior changed**  

Error type values are now keyword names such as minLength instead of numeric ValueErrorType codes. Code that compares error types must be updated. [github.com](https://github.com/react-hook-form/resolvers/releases/tag/v7.0.0)
- **Behavior changed**  

Validation error messages use TypeBox 1.x wording, so code that matches on message text may need updating. [github.com](https://github.com/react-hook-form/resolvers/releases/tag/v7.0.0)
- **Configuration changed**  

The typebox resolver requires typebox ^1.0.0 as a peer dependency instead of @sinclair/typebox. Install typebox 1.x and remove @sinclair/typebox. [github.com](https://github.com/react-hook-form/resolvers/releases/tag/v7.0.0)
- **Signature changed** `typebox:typeboxResolver`  

Was function typeboxResolver<Schema extends TObject, Context>(schema: Schema | TypeCheck<Schema>): Resolver<Static<Schema>, Context, StaticDecode<Schema>>; now function typeboxResolver<Schema extends TObject, Context, TypeContext extends... [npmjs.com](https://www.npmjs.com/package/@hookform/resolvers/v/7.0.0)

## 6.0.0

4 breaking changes, first published October 19, 2026.

- **Removed**  

The effect-ts resolver now requires effect@^4.0.0 and no longer supports Effect v3. Schemas must be migrated to the Effect v4 Schema API. [github.com](https://github.com/react-hook-form/resolvers/releases/tag/v6.0.0)
- **Behavior changed**  

Error type values change, for example Type becomes InvalidType and Missing becomes MissingKey. Code that matches on the old type strings must be updated. [github.com](https://github.com/react-hook-form/resolvers/releases/tag/v6.0.0)
- **Behavior changed**  

Default error messages change text, for example 'is missing' becomes 'Missing key', and the received value is no longer included. Code that matches on these messages must be updated. [github.com](https://github.com/react-hook-form/resolvers/releases/tag/v6.0.0)
- **Signature changed** `effect-ts:effectTsResolver`  

Was function effectTsResolver<Input extends FieldValues, Context, Output>(schema: Schema.Schema<Output, Input>, schemaOptions: ParseOptions | undefined, resolverOptions: {mode?: 'async' | 'sync'; raw: true;}): Resolver<Input, Context... [npmjs.com](https://www.npmjs.com/package/@hookform/resolvers/v/6.0.0)

## Check your code

These are the changes. To see which of them reach your code, [scan a public repository](https://since.dev/scan.md), or have your coding agent call `check_code` with your manifest or lockfile over [MCP](https://since.dev/docs.md#mcp). [The API](https://since.dev/docs.md#api) reads every change in every version, not only the newest. On Team and up, a fix pull request opens for the changes that reach a connected repository. Nothing merges or deploys.

## Put your code on continuous management.

Scan a public repository now, or give your agent one line.

### See how out of date your code is.

[Scan a repository](https://since.dev/scan.md). Any public GitHub repository. No sign-in.

### Tell your agent what changed since it was trained.
