<ul>
<li>Undeclared required keys now retained in variant runtime validation
- When combining <code>--read-only-write-only-model-type</code>
request/response variants with <code>--schema-validator-type</code>
runtime validators, generated models now keep runtime validation rules
for required keys that are not declared as properties (for example keys
required via additionalProperties or if/then/else), whereas these rules
were previously dropped from the variant models. Regenerated Request and
Response models therefore enforce stricter validation and may reject
payloads that the previously generated validators accepted (<a

<h2>0.80.0</h2>
<h2>Breaking Changes</h2>
<h3>Code Generation Changes</h3>
<ul>
<li>Python union annotations preserve unsupported member types - When
generating from Python input models, unions containing members such as
<code>Callable</code> retain each member type and the original union
order instead of repeating the first non-null type. Regenerated
annotations change for the affected unions and nested containers. (<a
href="https://redirect.github.com/datamodel-code-generator/datamodel-code-generator/issues/3947">#3947</a>)</li>
<li>Optional nested factories require a callable empty constructor -
With <code>--use-default-factory-for-optional-nested-models</code>, an
optional child with required constructor fields, including inherited
fields, keeps its normal <code>None</code> or <code>UNSET</code> default
instead of receiving a factory that fails when called without arguments.
(<a
href="https://redirect.github.com/datamodel-code-generator/datamodel-code-generator/issues/3953">#3953</a>)</li>
<li>Safe frozen set items use native Pydantic hash generation - Safely
hashable frozen Pydantic v2 models used as set or frozenset items rely
on the native hash in place of the explicit identity-hash assignment.
Mutable models and models outside the supported safe cases retain the
previous generated hash behavior. (<a
href="https://redirect.github.com/datamodel-code-generator/datamodel-code-generator/issues/4025">#4025</a>)</li>
<li>GraphQL msgspec typename fields retain separate inherited slots -
For affected GraphQL inheritance collisions, generated models keep
inherited synthetic typename slots separate from colliding child user
fields, which receive distinct Python names while retaining their wire
aliases. Python attribute names in these affected hierarchies can differ
from earlier output. (<a
href="https://redirect.github.com/datamodel-code-generator/datamodel-code-generator/issues/4045">#4045</a>)</li>
<li>Constrained root aliases retain their validation - With
<code>--use-root-model-type-alias</code>, constraints are retained in
the alias where supported; affected roots otherwise use a
<code>RootModel</code> class instead of an unconstrained alias.
Unconstrained aliases retain their prior form, and an existing custom
root-alias template keeps its selection and remains responsible for its
own constraints. (<a
href="https://redirect.github.com/datamodel-code-generator/datamodel-code-generator/issues/3962">#3962</a>)</li>
<li>Eligible compound property names use string key types - Eligible
string alternatives in <code>propertyNames</code> generate inline
constrained string key types instead of nested-model keys. This changes
ordinary key annotations for affected schemas; custom schema runtime
validators remain conditional on <code>--schema-validator-type
pydantic-v2</code>. (<a
href="https://redirect.github.com/datamodel-code-generator/datamodel-code-generator/issues/3970">#3970</a>)</li>
<li>Opt-in schema validators enforce undeclared required names - With
<code>--schema-validator-type pydantic-v2</code>, required property
names absent from generated fields are checked against the raw object
input, including applicable pattern intersections. Payloads missing
those required names are rejected where the previous validators accepted
them; this fix does not add a validator when the option is disabled. (<a
href="https://redirect.github.com/datamodel-code-generator/datamodel-code-generator/issues/3988">#3988</a>)</li>
<li>Mapped allOf roots retain compatible constraints - For affected
<code>allOf</code> roots with an outer format or type mapping,
compatible numeric or string constraints are preserved while constraints
incompatible with the mapped runtime type are omitted. Regenerated
annotations change for these roots and avoid applying incompatible
constraints to date, UUID, or other mapped values. (<a
href="https://redirect.github.com/datamodel-code-generator/datamodel-code-generator/issues/4043">#4043</a>)</li>
