I'm thrilled to announce the first release candidate for Starlette 1.0.</p> <p>Starlette was created in June 2018 by Tom Christie, and has been on ZeroVer for years. Today, it's downloaded almost <a href="https://pypistats.org/packages/starlette";>10 million times a day</a>, serves as the foundation for FastAPI, and has inspired many other frameworks. In the age of AI, Starlette continues to play an important role as a dependency of the Python MCP SDK.</p> <p>This release focuses on removing deprecated features that were marked for removal in 1.0.0, along with some last minute bug fixes. It's a release candidate, so we can gather feedback from the community before the final 1.0.0 release soon.</p> <p>A huge thank you to all the contributors who have helped make Starlette what it is today. In particular, I'd like to recognize:</p> <ul> <li><a href="https://github.com/lovelydinosaur";>Kim Christie</a> - The original creator of Starlette, Uvicorn, and MkDocs, and the current maintainer of HTTPX.

href="https://github.com/koxudaxi/datamodel-code-generator/compare/0.56.0...0.56.1";>https://github.com/koxudaxi/datamodel-code-generator/compare/0.56.0...0.56.1</a></p> <h2>0.56.0</h2> <h2>Breaking Changes</h2> <h3>Code Generation Changes</h3> <ul> <li>Generated default field syntax changed - Fields with structured defaults (dicts, lists, model references) now use <code>Field(default_value, validate_default=True)</code> instead of <code>default_factory=lambda: TypeAdapter(...).validate_python(...)</code> or <code>default_factory=lambda: Model.model_validate(...)</code>. This produces simpler, more readable code but changes the generated output format. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3050";>#3050</a>)</li> <li>TypeAdapter import removed from generated code - Generated models no longer import <code>TypeAdapter</code> from pydantic since <code>validate_default=True</code> handles validation natively. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3050";>#3050</a>)</li> <li>Default value handling for model-referencing fields rewritten - Fields with defaults referencing Pydantic models (BaseModel, RootModel, type aliases) now generate <code>Field(<raw_value>, validate_default=True)</code> instead of <code>default_factory=lambda: Model.model_validate(...)</code>, <code>default_factory=lambda: TypeAdapter(...).validate_python(...)</code>, or <code>default_factory=lambda: Model(...)</code>. Empty collection defaults changed from <code>default_factory=list</code>/<code>default_factory=dict</code> to <code>Field([], validate_default=True)</code>/<code>Field({}, validate_default=True)</code>. The generated code is semantically equivalent under Pydantic v2 but textually different, which will break snapshot tests or tooling that matches exact output. <code>pydantic.TypeAdapter</code> is no longer imported in generated code. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3070";>#3070</a>)</li> <li>Default values for model-referencing fields now use <code>validate_default=True</code> instead of <code>default_factory</code> lambdas - Fields with structured defaults (dicts, lists, or scalars referencing Pydantic models/RootModels) previously generated <code>default_factory=lambda: ModelName.model_validate(value)</code> or <code>default_factory=lambda: ModelName(value)</code>. They now generate <code>Field(value, validate_default=True)</code>, producing simpler but different output. Empty collection defaults changed from <code>default_factory=list</code>/<code>default_factory=dict</code> to <code>Field([], validate_default=True)</code>/<code>Field({}, validate_default=True)</code>. Users who regenerate code will see different output. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3071";>#3071</a>) Before: <pre lang="python"><code>count: CountType | None = Field(default_factory=lambda: CountType(10)) items: dict[str, Item] | None = Field(default_factory=dict, title='Items') </code></pre> After: <pre lang="python"><code>count: CountType | None = Field(10, validate_default=True) items: dict[str, Item] | None = Field({}, title='Items', validate_default=True) </code></pre> </li> <li>Default values for fields referencing models now use <code>validate_default=True</code> instead of <code>default_factory=lambda:</code> - Fields with structured defaults (dicts/lists) that reference Pydantic models previously generated <code>default_factory=lambda: Model.model_validate(...)</code> or <code>default_factory=lambda: TypeAdapter(Type).validate_python(...)</code> patterns. They now generate the raw default value directly with <code>validate_default=True</code> (e.g., <code>Field({'key': 'val'}, validate_default=True)</code> instead of <code>Field(default_factory=lambda: Model.model_validate({'key': 'val'}))</code>). This changes the generated code output and may affect users who depend on the exact generated code structure, pin generated output in tests, or use custom post-processing. The runtime behavior should be equivalent for Pydantic v2 users. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3072";>#3072</a>)</li> <li><code>TypeAdapter</code> import removed from generated code - Generated code no longer imports <code>pydantic.TypeAdapter</code> for default value handling. Code that previously used <code>TypeAdapter(...).validate_python(...)</code> in default factories now uses inline defaults with <code>validate_default=True</code>. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3072";>#3072</a>)</li> <li>Integer and boolean discriminator values now supported in generated Literal types - Discriminator fields previously only generated string literal values. They now support <code>int</code> and <code>bool</code> discriminator values (e.g., <code>Literal[1]</code> instead of <code>Literal['1']</code>), which changes generated code for schemas using integer discriminator mappings. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3072";>#3072</a>)</li> </ul> <h3>API/CLI Changes</h3> <ul> <li><code>ValidatedDefault</code> and <code>WrappedDefault</code> classes removed - These internal classes were exported from <code>datamodel_code_generator.model.base</code> and have been removed. Code importing these types will break: <pre lang="python"><code># Before (broken) from datamodel_code_generator.model.base import ValidatedDefault, WrappedDefault </code></pre> (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3050";>#3050</a>)</li> <li><code>SUPPORTS_WRAPPED_DEFAULT</code> and <code>SUPPORTS_VALIDATED_DEFAULT</code> class variables removed - These flags were removed from the <code>DataModel</code> base class. Custom model classes that override these variables will see attribute errors. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3050";>#3050</a>)</li> <li>Internal types <code>ValidatedDefault</code> and <code>WrappedDefault</code> removed - The <code>datamodel_code_generator.model._types</code> module was deleted and <code>ValidatedDefault</code>/<code>WrappedDefault</code> are no longer exported from <code>datamodel_code_generator.model.base</code>. Code that imports or subclasses these types will break. The <code>SUPPORTS_WRAPPED_DEFAULT</code> and <code>SUPPORTS_VALIDATED_DEFAULT</code> class variables were removed from <code>DataModel</code> and its subclasses; custom model classes referencing these attributes will need updating. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3070";>#3070</a>)</li> <li>Removed <code>WrappedDefault</code>, <code>ValidatedDefault</code> classes and <code>SUPPORTS_WRAPPED_DEFAULT</code>, <code>SUPPORTS_VALIDATED_DEFAULT</code> class variables - The <code>WrappedDefault</code> and <code>ValidatedDefault</code> classes from <code>datamodel_code_generator.model._types</code> (re-exported via <code>datamodel_code_generator.model.base</code>) have been deleted. The <code>DataModel</code> class variables <code>SUPPORTS_WRAPPED_DEFAULT</code> and <code>SUPPORTS_VALIDATED_DEFAULT</code> have also been removed. Code that imports or references these will break. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3071";>#3071</a>)</li> <li>New <code>--allow-remote-refs</code> / <code>--no-allow-remote-refs</code> CLI option and <code>allow_remote_refs</code> config field - Remote <code>$ref</code> fetching over HTTP/HTTPS now emits a deprecation warning by default. Pass <code>--allow-remote-refs</code> to suppress the warning, or <code>--no-allow-remote-refs</code> to block remote fetching entirely. In a future version, remote fetching will be disabled by default. Users relying on remote <code>$ref</code> resolution should add <code>--allow-remote-refs</code> to their invocations to avoid the deprecation warning and prepare for the future default change.

Users catching specific <code>httpx</code> exceptions from remote ref resolution will need to catch <code>SchemaFetchError</code> instead.

(<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3050";>#3050</a>)</li> <li>Default value handling for model-referencing fields rewritten - Fields with defaults referencing Pydantic models (BaseModel, RootModel, type aliases) now generate <code>Field(<raw_value>, validate_default=True)</code> instead of <code>default_factory=lambda: Model.model_validate(...)</code>, <code>default_factory=lambda: TypeAdapter(...).validate_python(...)</code>, or <code>default_factory=lambda: Model(...)</code>. Empty collection defaults changed from <code>default_factory=list</code>/<code>default_factory=dict</code> to <code>Field([], validate_default=True)</code>/<code>Field({}, validate_default=True)</code>. The generated code is semantically equivalent under Pydantic v2 but textually different, which will break snapshot tests or tooling that matches exact output. <code>pydantic.TypeAdapter</code> is no longer imported in generated code.

This produces simpler, more readable code but changes the generated output format. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3050";>#3050</a>)</li> <li>TypeAdapter import removed from generated code - Generated models no longer import <code>TypeAdapter</code> from pydantic since <code>validate_default=True</code> handles validation natively. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3050";>#3050</a>)</li> <li>Default value handling for model-referencing fields rewritten - Fields with defaults referencing Pydantic models (BaseModel, RootModel, type aliases) now generate <code>Field(<raw_value>, validate_default=True)</code> instead of <code>default_factory=lambda: Model.model_validate(...)</code>, <code>default_factory=lambda: TypeAdapter(...).validate_python(...)</code>, or <code>default_factory=lambda: Model(...)</code>. Empty collection defaults changed from <code>default_factory=list</code>/<code>default_factory=dict</code> to <code>Field([], validate_default=True)</code>/<code>Field({}, validate_default=True)</code>. The generated code is semantically equivalent under Pydantic v2 but textually different, which will break snapshot tests or tooling that matches exact output. <code>pydantic.TypeAdapter</code> is no longer imported in generated code. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3070";>#3070</a>)</li> <li>Default values for model-referencing fields now use <code>validate_default=True</code> instead of <code>default_factory</code> lambdas - Fields with structured defaults (dicts, lists, or scalars referencing Pydantic models/RootModels) previously generated <code>default_factory=lambda: ModelName.model_validate(value)</code> or <code>default_factory=lambda: ModelName(value)</code>. They now generate <code>Field(value, validate_default=True)</code>, producing simpler but different output. Empty collection defaults changed from <code>default_factory=list</code>/<code>default_factory=dict</code> to <code>Field([], validate_default=True)</code>/<code>Field({}, validate_default=True)</code>. Users who regenerate code will see different output. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3071";>#3071</a>) Before: <pre lang="python"><code>count: CountType | None = Field(default_factory=lambda: CountType(10)) items: dict[str, Item] | None = Field(default_factory=dict, title='Items') </code></pre> After: <pre lang="python"><code>count: CountType | None = Field(10, validate_default=True) items: dict[str, Item] | None = Field({}, title='Items', validate_default=True) </code></pre> </li> <li>Default values for fields referencing models now use <code>validate_default=True</code> instead of <code>default_factory=lambda:</code> - Fields with structured defaults (dicts/lists) that reference Pydantic models previously generated <code>default_factory=lambda: Model.model_validate(...)</code> or <code>default_factory=lambda: TypeAdapter(Type).validate_python(...)</code> patterns. They now generate the raw default value directly with <code>validate_default=True</code> (e.g., <code>Field({'key': 'val'}, validate_default=True)</code> instead of <code>Field(default_factory=lambda: Model.model_validate({'key': 'val'}))</code>). This changes the generated code output and may affect users who depend on the exact generated code structure, pin generated output in tests, or use custom post-processing. The runtime behavior should be equivalent for Pydantic v2 users. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3072";>#3072</a>)</li> <li><code>TypeAdapter</code> import removed from generated code - Generated code no longer imports <code>pydantic.TypeAdapter</code> for default value handling. Code that previously used <code>TypeAdapter(...).validate_python(...)</code> in default factories now uses inline defaults with <code>validate_default=True</code>. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3072";>#3072</a>)</li> <li>Integer and boolean discriminator values now supported in generated Literal types - Discriminator fields previously only generated string literal values. They now support <code>int</code> and <code>bool</code> discriminator values (e.g., <code>Literal[1]</code> instead of <code>Literal['1']</code>), which changes generated code for schemas using integer discriminator mappings. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3072";>#3072</a>)</li> </ul> <h3>API/CLI Changes</h3> <ul> <li><code>ValidatedDefault</code> and <code>WrappedDefault</code> classes removed - These internal classes were exported from <code>datamodel_code_generator.model.base</code> and have been removed. Code importing these types will break: <pre lang="python"><code># Before (broken) from datamodel_code_generator.model.base import ValidatedDefault, WrappedDefault </code></pre> (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3050";>#3050</a>)</li> <li><code>SUPPORTS_WRAPPED_DEFAULT</code> and <code>SUPPORTS_VALIDATED_DEFAULT</code> class variables removed - These flags were removed from the <code>DataModel</code> base class. Custom model classes that override these variables will see attribute errors. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3050";>#3050</a>)</li> <li>Internal types <code>ValidatedDefault</code> and <code>WrappedDefault</code> removed - The <code>datamodel_code_generator.model._types</code> module was deleted and <code>ValidatedDefault</code>/<code>WrappedDefault</code> are no longer exported from <code>datamodel_code_generator.model.base</code>. Code that imports or subclasses these types will break. The <code>SUPPORTS_WRAPPED_DEFAULT</code> and <code>SUPPORTS_VALIDATED_DEFAULT</code> class variables were removed from <code>DataModel</code> and its subclasses; custom model classes referencing these attributes will need updating. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/3070";>#3070</a>)</li> <li>Removed <code>WrappedDefault</code>, <code>ValidatedDefault</code> classes and <code>SUPPORTS_WRAPPED_DEFAULT</code>, <code>SUPPORTS_VALIDATED_DEFAULT</code> class variables - The <code>WrappedDefault</code> and <code>ValidatedDefault</code> classes from <code>datamodel_code_generator.model._types</code> (re-exported via <code>datamodel_code_generator.model.base</code>) have been deleted. The <code>DataModel</code> class variables <code>SUPPORTS_WRAPPED_DEFAULT</code> and <code>SUPPORTS_VALIDATED_DEFAULT</code> have also been removed. Code that imports or references these will break.
