v0.7.0 (2020-01-23)

• BREAKING CHANGE: The http and bytes dependencies have been updated. They now match the tokio 0.2 ecosystem.

• BREAKING CHANGE: The Resource trait's api_version, group, kind and version methods are now API_VERSION, GROUP, KIND and VERSION associated consts of &'static str type.

• BREAKING CHANGE: The *List resource types like PodList and NodeList have now been combined into a single generic k8s_openapi::List<T> type. The API response types that contained these list types have been updated accordingly.

• BREAKING CHANGE: The optional parameters of create and replace operations are now emitted as a single common type - k8s_openapi::CreateOptional and k8s_openapi::ReplaceOptional respectively.

• BREAKING CHANGE: The response types of create, delete, delete-collection, list, patch, replace and watch operations have now been combined into generic CreateResponse<T>, DeleteResponse<T>, DeleteResponse<List<T>>, ListResponse<T>, PatchResponse<T>, ReplaceResponse<T> and WatchResponse<T> types respectively.

• BUGFIX: v1.16's k8s_openapi::apliextensions_apiserver::pkg::apis::apiextensions::v1::JSONSchemaPropsOrArray, JSONSchemaPropsOrBool and JSONSchemaPropsOrStringArray types are now generated correctly, just like their v1beta cousins.

• FEATURE: Added support for Kubernetes 1.17 under the v1_17 feature.

• FEATURE: A new k8s_openapi::ListableResource trait has been added to connect a resource type like Pod to its corresponding list type like PodList. Currently the trait only has one member - an associated const LIST_KIND that is the same as the list type's Resource::KIND.

Here are some demonstrative examples of the API changes:

• Pod::delete_namespaced_pod used to return DeleteNamespacedPodResponse. It now returns DeleteResponse<Self>.
• Pod::delete_collection_namespaced_pod used to return DeleteCollectionNamespacedPodResponse. It now returns DeleteResponse<List<Self>>.
• Pod::list_namespaced_pod used to return ListNamespacedPodResponse which had an Ok(PodList) variant. It now returns ListResponse<Self>, which has an Ok(List<Self>) variant.

Combining these response types has reduced the compile time and memory usage of the Rust compiler when compiling this crate. Notably, the compiler's memory usage now peaks at ~3 GiB from its earlier ~5 GiB, making it easier to use with environments limited to 4 GiB RAM, like CI VMs and Raspberry Pi's.

Corresponding Kubernetes API server versions:

• v1.8.15
• v1.9.11
• v1.10.13
• v1.11.10
• v1.12.10
• v1.13.12
• v1.14.10
• v1.15.9
• v1.16.6
• v1.17.2

v0.6.0 (2019-10-18)

• BREAKING CHANGE: Updated url dependency, and thus the re-export, to v2. The re-export is only used internally by code-generated API functions and is not part of any public signatures, so it is only a breaking change for you if you were also using it for your own code.
