 The 0.x prefix used in versions for this project is to indicate that breaking changes are expected frequently (several times a year). Breaking changes will increment the minor number, all other changes will increment the patch number. You can track the progress toward 1.0 [here](https://github.com/openapi-generators/openapi-python-client/projects/2).
 
+## 0.17.0 (2023-12-31)
+
+### Breaking Changes
+
+#### Removed query parameter nullable/required special case
+
+In previous versions, setting _either_ `nullable: true` or `required: false` on a query parameter would act like both were set, resulting in a type signature like `Union[None, Unset, YourType]`. This special case has been removed, query parameters will now act like all other types of parameters.
+
+### Features
+
+#### OpenAPI 3.1 support
+
+The generator will now attempt to generate code for OpenAPI documents with versions 3.1.x (previously, it would exit immediately on seeing a version other than 3.0.x). The following specific OpenAPI 3.1 features are now supported:
+
+- `null` as a type
+- Arrays of types (e.g., `type: [string, null]`)
+- `const` (defines `Literal` types)
+
+The generator does not currently validate that the OpenAPI document is valid for a specific version of OpenAPI, so it may be possible to generate code for documents that include both removed 3.0 syntax (e.g., `nullable`) and new 3.1 syntax (e.g., `null` as a type).

+Thanks to everyone who helped make this possible with discussions and testing, including:
