+## [0.49.0](https://github.com/koxudaxi/datamodel-code-generator/releases/tag/0.49.0) - 2025-12-25
+
+## Breaking Changes
+
+  ### SchemaParseError for Invalid Schema Data
+  * Schema validation errors now raise `SchemaParseError` instead of Pydantic `ValidationError` - When parsing invalid schema data (e.g., `"minimum": "not_a_number"`), the library now raises `SchemaParseError` instead of passing through Pydantic's `ValidationError`. Users catching `pydantic.ValidationError` for schema validation failures should update to catch `SchemaParseError`. The original error is preserved in the `original_error` attribute. (#2786)
+
+  ## Bug Fixes
+
+  ### CLI Now Correctly Outputs to stdout
+  * Fixed CLI to actually output to stdout when `--output` is not specified - The `--output` argument has always documented `(default: stdout)` in `--help`, but previously no output was produced. Now works as documented. (#2787)
+
+  ## Other Notable Changes
+
+  * `generate()` function now returns `str | GeneratedModules | None` instead of `None` - Existing code ignoring the return value is unaffected. (#2787)
+  * Error message for multi-module output without directory changed to be more descriptive. (#2787)
