+## 2.0.1 - 2026-04-13
+* fix: replace @JsonProperty with @JsonIgnore on request getter methods
+* Request objects across multiple endpoints used @JsonProperty annotations
+* on getter methods, which caused Jackson to inadvertently serialize request
+* fields into the JSON body when these objects were used in contexts that
+* triggered serialization. Replacing with @JsonIgnore ensures these request
+* POJOs are not accidentally serialized as JSON bodies — parameters are
+* instead passed as query/path parameters via the HTTP layer.
+* Additionally, refactors RetryInterceptor to instantiate a fresh
+* ExponentialBackoff per retry cycle rather than reusing a shared instance,
+* preventing potential state leakage across concurrent or sequential requests.
+* Key changes:
+* Replace @JsonProperty with @JsonIgnore on all getter methods in GetAggregationCountRequest, GetAuthorsRequest, and GetBreakingNewsRequest
+* Refactor RetryInterceptor to create a new ExponentialBackoff instance per retryChain() invocation instead of holding a shared instance
+* 🌿 Generated with Fern
