python-openapi/openapi-schema-validator (openapi-schema-validator)

v0.9.0

Compare Source

Features

• Enforce properties required flag #​290

Fixes

• OAS 3.1/3.2 discriminator is annotation-only #​279

Backward incompatibilities

• OAS31Validator and OAS32Validator no longer use discriminator-driven schema selection for oneOf, anyOf, or allOf.
• For OpenAPI 3.1 and 3.2, discriminator is now treated as a hint/annotation and does not change validation outcome.
• Validation results may change for schemas that previously relied on discriminator-based narrowing or on discriminator mapping resolution errors during validation.

v0.8.1

Compare Source

Features

• Speed up validate() with validator caching and optional schema-check fast path #​273

v0.8.0

Compare Source

Security

• Harden validate defaults for remote $ref resolution #​270

Backward incompatibilities

• By default, validate uses a local-only empty registry to avoid implicit remote $ref retrieval. To resolve external references, pass an explicit registry. Set allow_remote_references=True only if you explicitly accept jsonschema's default remote retrieval behavior.

v0.7.3

Compare Source

Features

• Support official OAS 3.2 dialect and set it as default #​263
• Add optional ecma-regex backend for strict OpenAPI pattern validation #​267

Fixes

• Fix OAS 3.0 byte format validation to enforce strict base64 #​265

v0.7.2

Compare Source

Features

• OAS 3.1 dialect registration and validator discovery #​262

v0.7.1

Compare Source

Features

• Add OpenAPI 3.2.0 support (OAS32Validator) #​256

v0.7.0

Compare Source

Features

• OAS30 strict validator #​251

Fixes

• Ignore readOnly/writeOnly set to False #​248
• Discriminator handling for non-object instances #​249
• Narrower handling around unresolved refs #​250

Breaking changes

• OAS30Validator with schema type string only accepts str (before accepted both str and bytes) #​251
• Added support for Python 3.12, 3.13 and 3.14 #​205 #​247
• Dropped support for Python 3.8 and 3.9 #​205 #​246
