2.59.6

(fix): Add domain-specific event properties (e.g. AssistantMessage, ChatMetadata, AudioOutput) and UnknownMessage to the generated WebSocket client interface. Previously, these events were only available on the concrete class, forcing consumers to downcast from the interface type to access them.

2.59.5

(fix): Skip mock server test examples with empty string path parameters. An empty path parameter causes the mock server to register a collapsed URL (e.g. /v0/tools/version/1) while the SDK client sends a double-slash URL (e.g. /v0/tools//version/1), resulting in a 404 from WireMock.

(fix): Fix dynamic snippet generation for literal types when generate-literals (or experimental-readonly-constants) is enabled. Inline literal properties now correctly omit the value (relying on the = new() default initializer), and named literal alias types emit new TypeName() instead of a raw string, preventing CS0029 compilation errors.

(fix): Fix file upload request properties declared as list<file> generating a single FileParameter field instead of List<FileParameter>.

2.59.4

(fix): Add GetSingle() fallback to JsonElementComparer number comparison. When two JSON numbers differ as decimals but match as singles, they represent the same float32 value and are now considered equal. This fixes mock server test failures for fields declared as format: float where C#‘s System.Text.Json serializes System.Single with a shorter decimal representation than the original JSON string (e.g. 0.10722749680280685 vs 0.1072275).
