TL;DR

Valibot now correctly infers types for array options within schema intersections, resolving a previous issue where types were incorrectly set to never.

Fixes Worth Knowing

intersect schemas now correctly infer input and output types for non-tuple array options, improving type safety and developer experience (schema composition).

TL;DR

Valibot now generates JSON Schema compatible with a wider range of environments, improving interoperability with tools that consume schema definitions (data validation tools).

Breaking

• Valibot requires peer dependency v1.4.0 or higher (minimum required version).

New

• JSON Schema generation is improved for broader compatibility (standard data format).

TL;DR

Valibot now supports validation error messages in Uzbek, improving accessibility for users in that region.

New

• Added Uzbek (uz) translations for validation errors.

Before You Upgrade

• Ensure your project uses Valibot peer dependency version 1.4.0 or higher.

TL;DR

Valibot now supports adding descriptive metadata (like titles) to schemas and validating decimal numbers, improving schema clarity and data validation capabilities.

Breaking

• NoPipe type renamed to SchemaWithoutPipe (internal type change).
• decimal action renamed to digits (affects code using this validator).

New

• Add metadata action to associate custom data with schemas (for documentation/tooling).
• Add digits action to validate strings as integers or floats (supports numeric input).

Fixes Worth Knowing

• Improved type inference for error paths (improves error message accuracy).

TL;DR

Valibot gains new input types and parsing methods, improving flexibility when defining and validating schemas, especially for complex data structures.

Breaking

• Object schema checks are less strict (schema definition).
• _stringify utility now handles custom objects (data serialization).

New

• Added parser and safeParser methods (data parsing functions).
• Introduced new input types: ContentInput, ContentRequirement, LengthInput, SizeInput, and ValueInput (schema definition).
• Added a config method (schema configuration).

Fixes Worth Knowing

• Fixed a bug in the forward method (error handling).
• Improved compatibility with various environments by relaxing object checks.
• Corrected _stringify for modified objects.

Before You Upgrade

• Review the official migration guide at https://valibot.dev/guides/migrate-to-v0.31.0/ to understand changes to object schema validation and stringification.
